Throttle

Zero Resistance Throttle

I am one to usually change my throttle tube out several times during the lifespan of my test machines. Plastic tubes wear out and it can get tough to pull the throttle after some use. I am not a huge fan of aluminum throttle tubes because they help throttle resistance minimally and usually give me a more rigid feeling through the right side of my bars. Yes, I am sensitive to rigidity and no not everyone will feel more rigidity when going to aluminum throttle tubes. I’ve had a ZRT Throttle in my possession for quite sometime, but have been hesitant to try it for a couple of reasons. Full disclosure, I dragged my ass on this test because you’re required to cut your handlebar down 1/2 inch on throttle side to compensate for the bearing and I am picky SOB when it comes to bars and like I mentioned previously it was an aluminum tube. I put my ego to the side and strapped on my clear minded testing brain and came away with these thoughts:

How does it work? Simply put, there are two radial ball bearings on each end of the tube. One located inside the throttle housing and one on the end of the handlebars. This gives the throttle assembly an ultra smooth action and a claimed longer lifespan. Unlike traditional plastic throttle tubes, the weight of the rider either pushing or pulling on the throttle will create some type of “friction”. The longer this goes on, the more the throttle and handle bars deteriorate and I have seen the right side of my bars look like slot car tracks in the past. Inserting two bearings within the throttle tube helps eliminate wear and friction, making your throttle assembly ultra smooth.

So does it work? Yes, it does and sometimes too well! What I mean by “too well” is that it works so good that sometimes I get whiskey throttle when I get tired or have massive arm pump. This throttle is so smooth that it can be easy to grab a handful when sometimes you weren’t expecting to. However, once I got used to the buttery twist, my whiskey became less and less. This is by far the biggest difference I have felt from an aftermarket throttle tube. The fears I had of cutting my bars and getting a different feel quickly went away when I rode out on the track. The 1/2 inch of bar loss was made up by the ZRT and my 802mm of bar width remained the same. Oh and trust me, if it didn’t feel the same, I would have felt it. Now when I go back to other test bikes that don’t have the ZRT tube on, it feels stiffer and harder to pull. We have been running the ZRT tube on our Husqvarna FC450 machine for almost 30 hours and have done nothing to it. I like that it feels as good as when we put it on and we have done zero maintenance to it.  

Of course there is a downside and the downside is that it costs $179.95! Now to most this is outrageous right? But to some, this costly part is worth it. For example, I would want a ZRT if I owned a KTM/Husqvarna/Gas Gas. Why? I am not a lock on grip guy, so I would normally go straight to an aftermarket throttle tube and instead of purchasing a cheaper plastic tube or an aluminum throttle, I would spend the money to get the ZRT. If you plan on keeping your bike for a few years or even if you get a new bike every year (albeit the same brand) this throttle tube is worth the cost.
