Ride Engineering 23.5mm Offset Split Triple Clamps (2021 Honda CRF450R)

I have been looking for some added stability and comfort from my 2021 Honda CRF450R test machine since I got it and although my suspension setting has evolved/improved over time, I still need some compliancy from this machine. I have been working with Adrian over at Ride Engineering on some split triple clamps for over a year now and we finally have come up with a feel that I think is better than stock. I have yet to test any other competitors clamps back to back as Ride Engineering is one of only a couple aftermarket companies that are making different offset clamps. I have tried a 24mm offset on the 2020 Honda CRF450R and really liked how it made the Honda have a “slower” feeling chassis. Slower in this sense was a good thing for the Honda as it calmed the chassis down on rough tracks for me. So in order to get some added chassis compliance, I tested Ride Engineering’s 23.5 offset clamp for the new generation Honda CRF450R and here is what I took away from the test. 

Stats:

The Ride Eng. 2021 CRF450R/RX Split Triple clamps are available in Red or Black, come in two offsets and cost $649.90. Custom colors available for $100 additional if you want a custom set. The Ride clamps save you 10oz. in weight and come in 22mm offset or the new 23.5mm option. A Showa steering damper option is available without drilling your frame so no need to stress on that. The bar position on 22mm offset is 8mm forward of stem hole allowing a 5mm or 11mm bar position, with Ride Engineering’s one piece bar mount ($104.95), also available in 7/8” version. The bar position on 23.5mm is 9.5mm forward of stem hole allowing a 6.5mm or 12.5mm bar position with Ride Eng.’s one piece bar mount (I preferred mine set at 12.5mm). Note: Stock OEM bar mounts will fit and affect the numbers above by 2mm (3mm or 13mm on 22s & 4.5mm & 14.5mm on 23.5s).   

How Do The Ride Engineering 23.5’s Affect The 2021 Honda CRF450R?: 

I will be quite honest with you… We went through a couple of versions before I felt that it was good enough to sell to the public. The first couple versions didn’t have the compliancy I needed nor did we have a different offset yet that I preferred. The first thing that I noticed with the Ride Engineering 23.5mm offset clamps is that it took away some of the dreaded vibration that the 2021 CRF450R has through the bars. Once I pulled out onto the track and started to accelerate I could feel less harmonics/vibration coming through the Pro Taper bars. What I wanted from the 2021 Honda CRF450R (as well as from the Ride clamps) was a calmer entrance in/through corners, less oversteer, better straight line stability, and increase in front tire tracking. 

I got all of this with the new 23.5 Ride Engineering setting! With my fork set at 2-3mm in the clamps as well as a rear shock sag measurement of 105mm I had a CRF450R that was less harsh feeling through my hands. Now the Honda didn’t quite give that sting through my arms on flat landings and gave the front end an increased flex feeling. Diving into ruts that start to get hooked, didn’t give me the front end knifing (oversteer) that I experienced at times with a 22mm offset. We call this cornering stability in the testing world and the new 23.5mm setting gave me increased cornering stability. Let’s face it, we all love the way the Honda corners, but sometimes it can corner too good and cause some in consistencies in your cornering technique. This 23.5mm offset Ride clamp still gives you that easy to lean front steering feel of the Honda, but improves area 2-3 (mid-exit) in corners.
Straight line comfort has also been improved thanks to losing some rigidity up near the head tube area. When testing the Honda CRF450R I never could have suspected that the OEM clamp was some of the problem when it came to getting a harsh feeling. Hitting square edge and braking bumps with the 23.5 Ride clamps gave me less harshness and improved my fork feel. The fork now seemed to move more in the stroke and had a slightly softer feel to it, which was nice, but also forced me to adjust my fork setting somewhat. With the Ride 23.5 clamps, I had to stiffen up my fork setting one click and slow the fork don one click also. Doing this gave me a better front tire feel when leaning on throttle. I ended up getting better front tire tracking (when stiffening/slowing the fork) when cutting across rough sections of the track. Once I figured that I could go stiffer with my setting it actually brought up the performance/comfort feel of the Honda CRF450R. The stock torque specs of 15 ft. lbs. on the top clamp and 12 ft. lbs. on the bottom clamp is recommended, but if you end up purchasing a raw/silver clamp, you can go to a 14/11 setting. 

So what’s the negatives? Honestly for a vet rider like myself, there aren’t too many… I do know that this isn’t a cure all for the rigidity issues of the CRF450R, but it does help a noticeable amount. When I let another Honda rider/owner try my test bike with the clamp, he immediately thought his OEM clamp was too stiff feeling. The negative for me is that you may have to adjust your suspension (to compensate for the softer feeling clamp) a little after installation, but to me having to do some minor clicker adjustments isn’t too much to ask for added comfort. Plus, y’all are Honda owners. You’re used to tinkering on your bikes right? I know I am when I ride this machine. This Ride Engineering 23.5mm offset split clamp will eliminate some of the tinkering you’re doing at the tracks most days by 40%, so you can ride more and be a test rider less. 

If you do end up getting the red colorway, please try to cover your clamps up with a towel or something when your bike is siting in the pits. The sun will fade the anodizing over time, so bring an EZ-UP or a towel to cover up your investment. These clamps are sexy looking so take care of them! If you’re a C rider worried about if you will lose that cornering ability of your Honda, have no fear, adding these clamps to your machine will not negatively affect how easy the Honda will lay over in corners. In fact, it might help you improve your corners as the CRF450R will setting into the corners better with this 23.5 offset.

Ride Engineering Split Triple Clamps (KTM/Husqvarna)

The stock KTM/Husqvarna clamps are too stiff for me! What about you? Well, if you’re here reading this, chances are they might be too rigid for you as well!  It’s odd because most other manufacturers OEM clamps are on the soft side, but the Austrians had something more rigid in mind when making these stock clamps. So in search of other options besides an X-Trig ROCS or a KTM Factory Edition clamp, I went out and tried Ride Engineering’s new split clamp. When Ride Engineering set out to build the KTM clamps, they’ve been designed with four goals in mind: 1) Optimize body position: (Bar position 3mm back from stock). Ride Engineering also offers optional offset for their bar mounts providing 4 bar positions as measured from the stem hole: 6mm forward, 9mm forward, 15mm forward & 18mm forward (using stock bar mounts your positions are either 7mm or 17mm forward); 2) Flex: this new split design made from 2024 aluminum is said to provide better comfort; 3) Improve the handling with a new gull wing design; 4) Place the upper pinch bolts in the front and allows for different aftermarket handguard mounts. Each set comes with a frame mounted hour meter relocation bracket so that you can retain your OEM hour meter. So how did they perform on the track? We break it down for you here. 

The stock KTM triple clamps are stiff natured and can make your orange bike feel rigid/harsh. My goal for this test was to find less front end vibration through the bars, more front end comfort, as well as try to get a more precise front end feel through corners, without getting added rigidity on hard pack/rough straights. Basically get a more compliant KTM 450 SX-F, but that is sometimes tough to do right? The good news is that this is exactly what I found with the Ride Engineering Split Clamps. The Ride Engineering clamp on the KTM 450 SX-F provided enough flex on small bumps, which gave me less of a stiff feel through the bars, yet was also stiff enough to give me a positive front wheel lean angle through flat corners. The Ride Engineering clamp is most noticeable when diving deep into a rut where there is a huge load put on the front end, forced by the rider. The chassis positivity through this area is much better than the stock clamps. The stock clamps have a tendency to give the rider a rigid feel when weighting the front end (although slightly more positive feeling), deflection on de-cel bumps and vibration that is not very friendly. The Ride Engineering clamp gives the front end more tire contact patch feel because it allows the front end to absorb more of what the track is offering the rider. Going firmer on the triple clamp can give a rider more positivity at times, when leaning into a corner, but in this case, I felt like I could get into a corner much easier with the Ride clamps. Straight line stability is improved because of the bump absorption character of the Ride clamp and vibration is also down which gives the bike a tighter, less clapped out feel. Also do yourself a favor and get rid of those stock Neken handlebars. Buy some Pro Taper EVO bars and thank me later!

Compared to a factory KTM clamp (that comes on the Factory Edition) the Ride Engineering clamp does have a little more flex to it than the KTM FE clamp. The two share the same split design, but offer different flex characters on the track. The KTM FE clamp does have a slightly firmer feel, which does help area 2 of corners when pushing your front tire/front end hard while banking off of ruts. The KTM FE clamp does give a little more positivity in that area, but in all other areas of the track the Ride Engineering split clamp just has more comfort.  I tried the Ride Engineering Split Clamps with the stock mounts and the rider triangle of the bar mount position on the clamp wasn’t an issue for my 6’0 frame. I also have tried the Ride Engineering bar mounts, so if you’re taller and looking for more room, you might want to look into a set of the two piece bar mounts from Ride as well.

A lot of back to back testing went down against the KTM Factory Edition clamps in order to figure out how much flex was too much or too little.

Ride Engineering offers two offsets (22mm and 20.5mm), comes in four colors (black, orange, silver, LE blue) and redesigned with a 90mm span to accept the stock bar mounts and mounting hardware. The $689.90 price tag is also not as steep as some of the other clamps in its class and to me Ride Engineering is one of the few aftermarket chassis part companies that actually test their own products. To have an owner that rides his own parts, then makes an educated decision on if it’s better than stock, is pretty damn cool.

Ride Engineering 22mm Triple Clamp and One Piece Bar Mount (Suzuki RM-Z450)

Ride Engineering’s 2020 Suzuki RM-Z450 22mm offset triple clamps (stock is 21.5mm) are anodized black, are 4.5 ounces lighter than stock and grip the fork 12mm higher up than the stock clamp. The one-piece bar mounts feature 12mm posts instead of 10mm for much-needed additional strength. The bar mounts retain the stock height and can be adjusted plus or minus 3–5mm and 5-10mm spacers are available for bar-height adjustment. Finally, soft poly cones isolate the bar post from the triple clamps, which provide additional plushness for your hands. The clamps come equipped with a steering stem and a tapered bearing pressed on, so they are ready to install once you unbox them.

The Suzuki RM-Z450 doesn’t need much help through corners, but it does need a little help in between each corner. The stock RM-Z450 is a little rigid feeling, can get a little twitchy on de-cel bumps and give the rider some oversteer when trying to load the front end on flat corners. It needs a little more stability and less of a harsh feel around the track. This is where the 22mm Ride Engineering Triple Clamps and one-piece bar mounts come into play. The clamping zones where the Ride Engineering lower clamp grip the fork leg are 12mm higher than stock. What this does is provide a different fulcrum point that allows the fork to get some additional flex. What this does is translate the RM-Z450 into a slightly more forgiving ride without sacrificing the cornering characteristics.

The 22mm offset helps settle the RM-Z450 into area 1 of corners for me as well as my test riders. With the fork set at 5mm up in the clamp the RM-Z450 now drops into a rut without that off throttle front end wiggle and the RM-Z450 now has an increase in cornering stability. Cornering stability comes into play when the rut is hammered and chopped out. The 22mm clamps provide more comfort in those conditions slightly more and allows the Suzuki to settle better. 

The adjustability of the bar mounts allows a wide range of riders the ability to dial in their cockpit area as well. For Ride Engineering weight savings and a more forgiving feel are always the goal and they seemed to accomplish this with this Suzuki set up. The Ride Engineering bar mount cones come in three durometers, which allow you to dial in the degree to which the bar mounts will give under loads. The softer the cone, the more movement you get, which increases comfort, but also can feel disconnected when you push into corners very hard. Naturally, some faster riders DO NOT like the bar mounts flexing and they prefer the stiffest of the bar mount cones, but I am more of a medium, more flex type of cone guy. 

The Ride Engineering RM-Z450 triple clamps offer some real performance value ($549.99 clamps and $104.95 for the mounts) and are offered in a cool blue and black anodized look. An investment like this should offer some sort of performance advantage on the track, not just look pretty. The Ride Engineering clamps/mounts offer a change in the handling and to me it was mostly for the better. I say “mostly” because I did feel like the Ride Engineering clamps will fade if you leave your bike in the pits, under the sun too long. Make sure to cover up your front end with a towel so that the sun is not beating directly onto the clamps anodizing.

Ride Engineering Full Performance Linkage (Husqvarna FC450)

Getting that comfortable feel as well as increased track toughness can be somewhat hard to find on the Husqvarna FC450. At least for me anyway. I can go to tracks that are soft and tighter and be completely happy with the Husqvarna and then go to a fast/choppy track that has more flowing corners and be confused on why this bike feels so different. I know a couple companies have been making different linkage ratios for the Husqvarna and KTM’s, but I wanted to try Ride Engineering’s performance linkage system on the FC450 to see if it actually improves upon the ride comfort on choppy tracks. 

 You might be saying to yourself, well what about the KTM Keefer? I do similar negative feelings on the KTM that I do on the white bike, but the Husqvarna does seem like it’s slightly more forgiving at times on rougher tracks. As you may already know this link also can work on the KTM, so if you’re on an orange bike, this test could also apply to you. I will be doing a full review on a couple different linkage systems (Ride Engineering/REP) on the KTM in the coming weeks, just to see if I can feel a difference between each. 

So what exactly am I looking for here? Why is there a need for a different linkage ratio on this machine? Why didn't the R&D team at KTM/Husqvarna choose the ratio that Ride Engineering came up with in the first place? I will give you some insider knowledge on the R&D process a little before we dive into this test. Sometimes when OEM R&D teams test suspension, often there is a few linkages that the test riders have to weed through to see which one works best for a wide range of riders on said bike. Setting up a bike for the masses is not easy to do and most of the time the OEM’s choose a setting that is more of a “comfort setting” than a performance setting to offset the stiffness of the chassis. Comfort is needed on any new production motocross bike and getting a suspension spec that coincides with the correct linkage ratio as well as frame stiffness can be tricky. Not every bike benefits from an aftermarket linkage ratio, so don’t think you need a linkage on every bike on the dealer floor. If you’re happy with the feeling that you get when you ride your machine then try not to overthink it. JUST GO RIDE! If you feel what we are describing in this test then possibly a linkage could benefit you. If you DO NOT feel the things we are explaining in this test, you can simply disregard it and move on to something else you want to add to your FC450.   

What I Want Out Of The Rear Of The Husqvarna 2020 FC450?

The rear of the Husqvarna FC450 feels somewhat rigid on acceleration chop and I can feel like my rear end is dancing around when hard on the throttle out of rough corners. I spent some days searching for some added traction/comfort by changing sag settings, spring rates and clickers, but came up empty handed. I also tried a WP Pro Component shock and that just exacerbated my problem a little more on acceleration, creating a firmer feel out of corners. Even though I had more hold up and less fade with the Pro Component shock, I wasn't happy with my acceleration feel. 

What Did I Get Out Of The Ride Engineering Performance Linkage? 

Ride Engineering recommends that you go up a spring rate with their linkage, but I wanted to try it with the stock 45 N/m spring rate as well as a 48 N/m. The Ride Engineering pull rods are 1.3mm longer than the stock rods and the knuckle is more progressive, so it ramps up different than the stock knuckle. Once installed and the sag was set to 104mm, I immediately felt slightly more comfort out of the rear of the bike on acceleration, but also noticed it being a little low for my liking in that area. On steeper jump faces or flat landings I felt like the shock bottomed and felt empty on high speed compression. After increasing the high speed compression, it helped a little on jump faces as well as helped the empty feel on slap down landings, but it hurt acceleration traction. I installed the heavier 48 N/m spring on, reset my sag, jumped back out on the track and was quickly greeted with a firmer feel, but the firm feel didn't translate into a harsher rear end like the stock linkage/spring had. 

The rear of the Husqvarna stayed up in the stroke more out of corners, but also had a freer feeling to it, which increased my rear end traction. Another positive to the heavier rear spring/Ride Engineering linkage combo was that the control of the Husqvarna was better when hitting de-cel bumps at speed. At times with the stock shock/link, the Husqvarna would ride too low and have a sudden kick to the rear end that left me with a sensation of less control leading into corners. With the heavier rear spring and Ride link the initial braking bump feel was firmer, yet the FC450 moved less when getting to the fifth, sixth, and seventh braking bump into corners. I could hold on the throttle a little longer because I had more control as well as better action of the rear end. If there was a negative to the heavier spring/Ride Engineering link, I would have to say that it can make the Husqvarna a slightly slower cornering bike on initial lean, but to me I didn't mind the slight slower turn in feel. I know some of you may not like that, but if you find that this is bothering you then simply run your sag at 103mm and this can help initial turn in. 

Like I mentioned above, I tried the WP Pro Component shock with the Ride Link set up and it gave me a similar feeling that the stock shock/Ride link set up did, but with even more hold up when ridden aggressively (of course that has something to do with the valving as well). I liked that with the Ride Engineering knuckle/rod set up of the FC450 felt less firm on acceleration and yet still had more control on de-cel bumps. 

This Ride Engineering Performance Link is $449.90 and is available over at ride-engineering.com and fits current Husqvarna/KTM models. 

If you’re a KTM owner and looking for a little comparison, stay tuned for a REP/Ride Engineering Performance Link comparison as both companies make a different knuckle ratio for the white and orange machines. Will I be able to feel the difference? Find out soon! 

Ride Engineering Performance Link (KTM 125SX)

My son loves riding his 2020 KTM 125SX, but comments all the time on how he feels like the KTM sits taller than his Yamaha YZ125. When I watch him ride I notice that the rear end of his 125SX kicks him in his ass when hitting braking bumps and when that happens, it makes the front end dive too much on corner entry. He only weighs in at around 115 pounds, so going down a spring rate on the shock was a must, but to me, the bike still looked unbalanced on de-cel.

I called up Adrian at Ride Engineering and asked what he had for the KTM 125SX and we both agreed to try a rear link to see if that would help balance out the bike. This Ride Engineering link lowers the back of the KTM 125SX chassis by 7mm to try and improve the ride balance. I set the sag at 103mm with the Ride Engineering link versus the usual 105mm of sag that we were running on Aden’s KTM. Just know that you might have to adjust your air pressure setting on your AER fork to get the right front end feel, since you’re dropping the rear of the bike with the new link (more on that below).

For this test I had two KTM 125SX machines. One was set up for my son, with his softer shock spring and one was just a bone stock KTM 125SX with the sag set for me at 105mm. We started later in the day at a couple tracks on separate days to make sure the track was nice and broke in before we started to make our changes. Doing this ensures that the track doesn't change too much from each change we made to the orange machines. With the Ride Engineering link I noticed better tracking/acceleration coming out of choppy corners and slightly more stability off-throttle. I really liked that the link helped the ride attitude of the KTM when leaning, under throttle, on choppy terrain. I had more trust in the KTM when loading the chassis hard on throttle. I didn't get near as much kicking coming down rough hills and the overall cornering character didn’t suffer. I was worried that this Ride Engineering link would hurt turn in, but to my surprise it didn't affect the KTM’s easy natured turn in character. 

Aden’s comments didn't exactly mimic mine, but one comment that actually made sense was he did like that he felt lower to the ground, when sitting, and that helped him with his starts. When watching him ride the bike was visibly less busy in the rear and didn't give him as much kicking on de-cel. The length of the Ride Engineering pull rods are 1.3mm’s longer than stock and come in at a 149.5mm overall length. Aden doesn't know enough about chassis testing to give me some great feedback, but some of his comments overlapped mine. I more or less watch the bike when he rides and then decide if it’s a good direction or not. We decided to leave the Ride Engineering link on his bike after we both came to an agreement that he looked/felt better on a rough track with it on.

If you do decide to get the Ride Engineering Performance Link just know that you may have to adjust your AER fork pressure, if you’re still on air forks. Now with the Ride Engineering pull rods installed the rear end will ride a little lower, so the front end might seem a little high. Dropping the air pressure anywhere between .2-.5 bar might be needed to get some added front end traction. We dropped Aden’s air pressure from 8.3 bar to 8.1 bar at some tracks and even down to 8 bar at others. Try running your normal AER pressure when you first put on the Ride pull rods and see how your front end feels though corners. If you feel like your front end is tall, your front end is pushing, or have a vague front end feel, just try to drop your air pressure slightly. This will help let the fork use more of its stroke and get that front tire to bite into the ground more. 

The Ride Engineering Performance Link comes complete with bearings and seals and is not that difficult to install. I literally changed the link out at the track on several days. If you’re looking to get a little more stability and rear wheel traction without sacrificing cornering, then you might want to try this link. MSRP is $219.95, but you can use the code Keefer-20 to save 20% if you want to order through ride-engineering.com. 

Ride Engineering Axle/Axle Block Kit For KTM/Husqvarna

KTM/Husqvarna uses an axle that resembles a bolt with a nut on one end. Although it’s nice not to have to mess with the left side axle block when putting in the axle through the swingarm, it’s not so friendly on the rear end of the bike while you're riding. Why? Because when you’re heavy on the throttle coming out of corners the rear end of your machine will squat under load putting force on the axle/axle blocks that sometimes can make the shock feel rigid and harsh. If the axle blocks can’t semi float (when hitting bumps under throttle) there will be some added rigidity put on the swingarm. Although crazy to think about little things like this can make a noticeable difference with the handling of your machine. 

Ride Engineering makes a KTM/Husqvarna axle/axle block kit that eliminates the one-piece axle/axle block on the KTM/Husqvarna. Instead, it uses a Honda CRF450R rear axle combined with special CNC-machined axle blocks that slip into the KTM/Husqvarna swingarm. However, you will need the special axle blocks to properly space the borrowed Honda axle. The Ride Engineering axle blocks retail for $54.95, and they offer Honda rear axles for $44.95, but how do they work? 

I am not going to sit here and blow smoke up your asses and say everyone that has a KTM/Husqvarna are going to feel this modification. Could I feel the difference when going back to back with the stock axle/Ride Engineering axle block kit? Yes, I could, but to me I only could feel it when coming out of corners with square edge as well as fast choppy conditions. After installing the Ride Engineering kit the rear of the bike felt more compliant and had less spike/harsh feel. I could feel more rear wheel traction immediately out of corners as the rear of the KTM/Husqvarna stayed straighter under throttle. I also felt like I could stiffen up my shock’s low speed compression because I had a free-er feel to the rear of the bike under load. To me a modification like this is worth it because I can actually feel more comfort. I had some of my less sensitive test riders help me with this test and one of them couldn't feel a thing, so installing the Ride Engineering Axle Block Kit should be based on how sensitive of a rider you are. 

The Ride Engineering Axle/Axle Block Kit does not add weight to the machine and in fact weighs a couple grams less than the KTM/Husqvarna axle, just in case you’re on a diet and counting your grams. The Ride Engineering axle blocks themselves come in black or orange and have a unique design that allows easy chain alignment with tabs that have markings that can be easily seen and measured off the end of the swingarm. The blocks are also 2mm shorter than stock for more gearing options.  

If you’re a sensitive rider and can feel your way around a motorcycle fairly well this Ride Engineering axle/axle block kit is a great way to get more connection out of your orange or white ride. Head over to Ride-Engineering.com to check them out.
