8/3/2026 8:38pm 1st is half the ratio of 5th so should be about half the top speed assuming it's geared low enough that it can hit the red limiter in 5th. Otherwise more than half. 450 SX-F ratios according to Cycle News: 1st Gear: 16:32 ratio (2.000) 2nd Gear: 18:30 ratio (1.667) 3rd Gear: 20:28 ratio (1.400) 4th Gear: 22:26 ratio (1.182)...

5/22/2026 7:29pm Ask Race Tech! Their support is super helpful. I had a similar issue and if I remember correctly they told me I could substitute a slightly thicker shim and also offered to send more shims. The suspension was a huge improvement over stock!

7/28/2025 8:42pm Imagine you cut a hole with an area of 1/1000th of a square inch in the tank then put a piston in the hole with a 1 pound weight on it. The tank will be at 1000 PSI from that. Basically, since it's incompressible it takes no energy to raise it to any pressure you want. This is why they...

7/14/2024 7:45pm Nice job! I'd have killed for one of those on my 125! Is it noticeably harder to twist?

Because I race vet class with open displacement, my 125 really sucked as I got very poor starts and constantly had to battle through the pack. It can be frustrating if I can't make quick...

I don’t know why the op is getting so much hate. They didn’t even put a neck brace on him. First thing I said when it showed the mule bumping all over the place with the guy holding his hands around coops neck was why the **** do they not have a neck brace or him on a backboard?

4/23/2023 7:10pm Glad you solved it! Might have been a little hard on the bearing to tap it in with the shaft like that since it's driving it in by the inner race but I doubt it hurt it. I wouldn't worry about the liquid gasket.

4/22/2023 6:34pm You'll definitely need those bolts tight to keep it from leaking. I bet it'd act like that if one of the bearings isn't full seated in the case. I think you're getting close to finding the real problem now.

4/17/2023 7:21pm Is it possible to just use the 80 HP mode for the start and then automatically drop down to something more sane for the rest of the race?
