Every setup has its advantages and disadvantages... the CVT trans work great, I do a lot with snowmobiles and I love them once you get em dialed in. Plus CVT takes operator error out of the mix and you dont have to screw around with sprocket sizes as much... I give the KFX a lot of credit, everyone has their own tastes and its just another option to satisfy that taste... Anyone can be top dog once the technology is there, just spend enough money...In my opinion the CVT transmission is both a plus and minus for hill racing. I've won a lot of races because of how the CVT works. People get hung up on that word "automatic" and don't bother to understand how a CVT works.
A CVT is not like a cars auto tranny. A CVT (if set up right) will keep your motor at the RPM that makes the most horsepower. That is why my motor has that continuous drone all the way up the hill.
On a clutch bike the RPMs go up and down. So if your motor makes the most HP at 9000 rpm you are only at 9000 RPM for a moment before you have to shift again and the RPMS drop.
With a CVT, your engine goes to 9000RPM and stays there all the way up the hill if you have it clutched right.
The downside, I can't drop the clutch like you guys do. I can't rev the bike up to 6 grand or whatever and drop the hammer at the green light. What that means is my bike does a lot of wheelies off the line. I need a super long swingarm but honestly just fitting the bike in my truck with the +10 is a challenge.
