In a special unveiling event with top Honda amateur motocrossers during the AMA Amateur National Motocross Championship at Loretta Lynn's Ranch, American Honda unveiled the all-new 2018 CRF250R. Take a first look here.
2018 Yamaha YZ450F First Ride Impression
2018 Yamaha YZ450F First Ride Impression
The long awaited 2018 Yamaha YZ450F media introduction was at Glen Helen Raceway Wednesday and I got to burn A LOT of laps around the facility (so I could give you all some initial feedback). Yamaha introduced this 2018 beauty to us a couple months ago and the bike is completely new (but you can use your existing 2017 wheels if you want). The MSRP has increased $500.00 ($9,199.00) for 2018, but you’re getting more with the new bike than you were with the 2017 version. If you want to hear more about the 2018 YZ450F you can listen to the “Keefer Tested” podcast that is up now on pulpmx.com, iTunes, keeferinctesting.com and Stitcher. After I get back from Loretta’s look for more testing info on the 2018 YZ450F. In the meantime below is what the 2018 feels like in contrast to the 2017 machine.
Engine: The 2018 YZ450F’s engine is tilted more forward in 2018 and has a host of changes internally for increased power output (you can go to https://www.keeferinctesting.com/motocross-testing/2017/6/11/first-look-at-the-2018-yamaha-yz450f to see what those changes are. The engine character has a more of a free feeling (less engine braking) than the 2017 version. The 2017’s engine braking was heavier, but the 2018’s engine has less off that drag on de-cel. Which in return gives the bike a better ride attitude coming into corners. The bottom end is snappy and comes on strong (yet smoother than the 2017) and chugs into a very meaty mid range that pulls farther than the 2017. If you’re not careful the mid range pull can get away from you (while in third gear) accelerating out of corners, because that's how hooked up the 2018 gets! Top end is lengthened (farther pull) and has slightly more over-rev than the 2017. It is not as smooth on low end as the 2017.5 KTM 450 SX-F, but not as snappy as the 2018 CRF450R. It is somewhere in the middle. I feel like Yamaha did a great job of improving the engine to an already impressive character. When doing this they made it easier for me to ride aggressively.
With the changes Yamaha made it's easier to maneuver when the track gets hammered.
Suspension: The suspension feels much like the 2017 and moves in the stroke a lot. However this movement doesn't have as near the amount of pitching like the older YZ450F does. The fork still has good comfort over braking bumps, but has slightly more deflection on small acceleration chop (which is more of a chassis feel, but more on that later). I stiffened the fork up two clicks and slowed the rebound down one click and this helped calm the fork down on light bump absorption. When accelerating out of corners the fork can deflect when high in the stroke, but this setting change helped this feeling. The fork height is set flush from the factory and I didn't feel the need to move the fork from that setting at Glen Helen. The shock needs to have a sag setting between 100-102mm similar to the 2017 setting. However the rear of the 2018 does not have that stink bug feel to it like the 2017. Coming into corners the rear of the Yamaha has a better ride attitude (lower feeling on de-cel) and will not push (or overpower) the front end near as much as the older bike. The shock is a little soft like the fork (at the end of the stroke), but still has remained comfortable on acceleration chop. I did go 1/8 of a turn stiffer on high speed compression to help keep the rear end up on jump landings and steep faces. I feel like the suspension has a wider range of adjustability to maximize the comfort for a wide range of riders. I had Alex Ray testing with me and while he's a good 20 pounds heavier than me, he found a comfortable setting to go fast on.
No this is NOT Travis Preston! But...... We did put his number on our test bike, so he could see what his bike would look like with a rider who could actually scrub.
Chassis/Handling: The 2018 chassis feeling is much different than the 2017. The 2018 YZ450F corners much easier and feels lighter on “tip in” (entrance of corners). Mid corner push that last year’s bike had is not as apparent with the new frame. The front end sticks through corners and will not give the rider as much vague feeling. The Yamaha doesn't want to stand up on you mid corner and will give you confidence charging into corners like Travis Preston (you're welcome TP for the compliment). The downside to the new chassis is the stiffer feel it can bring on straight line stability. The front head tube area has a little stiffer feel on acceleration (hence the fork deflection) and gives the rider less of a tire contact patch (only on acceleration). It feels like the front end is not firmly planted when on throttle and dancesaround a little more than the 2017. Off throttle the front tire has good grip and doesn't deflect as much. This stiffer 2018 feeling is exactly the opposite of the 2017 Yamaha YZ450F. I would say with a little more suspension set up I could get rid of most of that feeling, so I will tinker. We complained about cornering with the Yamaha for years right? Well…. They listened and now we might have to adapt to a slightly less stable straight line chassis feel to get that cornering feel that we wanted.
Ergonomics: The 2018 is much slimmer when riding and easier to get farther forward on. I can move farther up on the seat and not have the shroud area hinder my leg movements in corners. The fat feeling shroud area is minimized and will not freak previous Honda or Kawasaki owners out there when deciding to move to this Yamaha for 2018. The middle part of the YZ450F (frame) is narrower and you are able to feel that when whipping the bike over jumps. The word “Flickable” is used a lot in the testing world and the Yamaha has more of it in 2018. The taller bar mounts take a little time to get used to, but the handlebar is the same bend/shape, so if you're a shorter rider (5’9 or below) just roll your bars back a little to compensate for the bar mount height if it bothers you.
The Yamaha is slimmer in the shroud area for 2018. .
Other Tidbits: When I can get an e-start without making the bike feel like a hog on the track I am all in! The 2018 Yamaha’s e-start battery only weighs 1.5 pounds and doesn't require the rider to pull in the clutch. It cranks over fairly easy and makes stopping to talk to your homies in the pits much easier in the summer time. You can download the Yamaha Power Tuner app to your phone and make your 2018 Yamaha YZ450F’s engine character tailored made for you. There are three pre-programmed maps already on the app, but you are able to fine tune your fuel and ignition parameters to your liking. Having someone hack into your machine should not be a problem because its a password set account just like your home’s wi-fi connection. It’s also cool that you are able to share/text your personal map to your buddies, so they can try what you came up with as well. I went with a stronger bottom to mid map (shown in this article) and this helped me carry third gear more through corners. I felt like I was in between gears on some tighter corners, so I wanted more grunt on low to mid range. By adding some fuel and advancing the ignition a little I was able to use third gear around 75% of the track at Glen Helen, which made the bike even easier to ride. Work smarter not harder.
Try this map for increased bottom to mid range.
The flat blue color the rims are good looking and lighter than last year’s design. If you don’t like them than you can always go with the white/cyan colored Yamaha with BLACK rims! They are reported to be stronger than last year’s stockers, so I will be testing this in the upcoming weeks!
So when do they arrive in dealers? I spoke with two Yamaha employees and both told me they didn't have a firm date yet, but most likely dealers will see them in 2-3 weeks time. The MSRP is $9,199.00. That is $500.00 more than the 2017. If there is one thing I strongly didn't like about the 2018 Yamaha YZ450F it is the seat. The seat foam is soft and I can feel the seat base when I am leaning through a corner hard. The corner of the seat’s foam is soft and the seat base and gas tank area (near seat) hit my butt bone and is uncomfortable during a long moto. I am going to try a firmer foam ASAP. The airbox cover is so easy to take off. There is one dzus fastener that holds it on and then it pops off. The air filter is held on by two clips that makes removal ten times easier. The airbox/intake noise is similar to last year’s, so for those that are used to it will not know any change in sound.
The flat blue rims grow on you and look so much better in person.
Wrapping it Up: So what’s the verdict? I have only had one day on the 2018 Yamaha, but from what it feels like it’s a better YZ450F. The chassis feels stiffer, but that makes for a better cornering blue bike that we haven't seen in….Well……Ever Right?….. I am going to be playing around and tinkering in the coming weeks so stay tuned for continual updates on keeferinctesting.com and pulpmx.com.
If you have any questions about this test you can email me at kris@keeferinctesting.com. Don’t freak out if I don’t get back to you right away, I have a wife that requires quality time and I must give that to her so I don't end up divorced! Cheers! -KK
