I have a completely stock 2020 yz250x and this was the first performance mod I did to it. The change is night and day. I won’t bother explaining it, as everyone else already does a good job of that!

Tim was/is a huge help in make sure everything went smoothly on the install as well as helped with any random yz questions I had (I have a lot, as this was my first 2 stroke ever).He also gave me some great advice for tuning the carb even further to get the most out of the new Hitlis system. Needless to say, the product is a 10/10 and Tim’s excellent help and customer service made it an 11/10. Quality all around experience and product. You truly get what you pay for in this.

I came from riding big four-stroke bikes like the DR650. When I first got my YZ250X, it was harder to ride than I expected. I thought I just needed more practice, but then I kept hearing about this HITLIS mod. After thinking about it for a while, I decided to try it.

The install was easy. Tim, the guy who made it, even helped me over the phone while I was putting it on. I now have about five hours riding with the HITLIS, and my bike feels completely different. It’s exactly how I thought the YZ250X would feel when I bought it—smooth, fast, and fun. The power is easier to control, and I don’t get as tired as before.

I did wonder if I should have just learned to ride the stock bike, but after trying this, I don’t think I’ll ever go back. Now I can focus on becoming a better rider instead of fighting the bike. Next, I’ll be working on the jetting with Tim’s help, and I plan to add a YZ250 head and GYTR flywheel weight. After that, I don’t think I’ll change anything else. I’m just excited to enjoy this bike for years to come.

This mod was definitely worth it to me.

This product is honestly a game changer if you want to ride the YZ platform for challenging, technical riding.

I'm on a 24 YZ250x with a 24 YZ250 cylinder and ignition with a bunch of bolt on goodies.

In every situation I am now riding a gear higher and am considerably quicker in the hard stuff since installing HITLIS.

Bike pulls so hard straight off the bottom but always controllable. I spent a fair bit of time in 1st gear before but now in 2nd and sometimes 2 gears higher.

Deadset the best mod you could do for your YZ.

Awesome work Tim.

Creo que hitlis debería venir instalado de fábrica, mejora significativamente el comportamiento de la motocicleta. Luego de la instalación, mi yz250x se siente con mayor poder, más torque y mucho más ágil y amigable de pilotear. Se puede conducir de forma más agresiva y fluida que antes, teniendo un margen de error mucho mayor. Desde el despacho hasta tener el producto en mis manos, transcurrió aproximadamente 1 mes. Cabe destacar que el servicio de venta y post venta es increíblemente bueno.

Don't sit on the fence anymore, just do it. I was worried it would turn my bike into a marshmallow but it still breathes fire when I wrap the throttle on. But when you want it to be tame and linear it just lugs like a champion. Best mod I've done. 06 yz250 Woods kit.
