Great product. Works as advertised.

To jest poprostu to czego szukałem,motor teraz płynie w terenie trudno to wszystko opisać kup i zobacz co potrafi Yz250 z hitlis w hard enduro!!!!

I installed the Hitlis woods kit on my YZ250 and it made the bike a whole new machine. The power is so controllable. I did a 2 hour cross country race with it and it made me less fatigued and safer throughout the race. I watched all of the videos before I even ordered the kit. They were so informative and detailed making the install very easy. 10 out of 10.

I installed the woods kit on my yz250x and it made the bike smooth and keep traction. In the tighter spots I don’t have to watch the clutch as much but still the same power when you twist that throttle.
It really calmed down the chassis of the bike the suspension feel. It is a must have for the yz!

The Hitlis is absolutely incredible around a track, the power builds strongly and smoothly throughout the RPM range and makes the power far more usable and no fanning of the clutch is needed! Strong, tractable power that allows you to get on the power far earlier in corners, and the bike seems to settle far better too. The flywheel weight I previously ran will be collecting dust in the shed from now on. I cannot recommend the Hitlis kit enough!!! Thank you Tim for your customer service and product!
