This has tamed the power delivery, making my riding experience better than expected….. seemingly linear power delivery that gives me time to react before the yz explosion is uncorked.

I called 3 different companies looking to find someone for advice for my yz250x as it has a cylinder works 300 kit. I wanted to change and tame the bike for the woods enduro we do here southwestern PA I finally came here read the story and talked to Tim himself and he gave honest opinions and great advice he sold me on the service and quick response. He gives honest recommendations off of experience and even without, he didn't say what was right and wrong but spread a respectful opinion of his own on everything.

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.
