I installed the HITLIS system on my 2024 YZ250X, and the difference is incredible. As a newer 2-stroke rider, the stock power delivery felt intimidating and abrupt at times. After installing the HITLIS, the bike became much smoother, more predictable, and significantly easier to control.
It lugs much better, has more usable torque everywhere, and the sudden “hit” is gone. The bike now pulls cleanly and smoothly through the entire RPM range while still feeling strong. I immediately noticed better traction and much more confidence on technical trails and when hopping logs.
Installation was straightforward, and the instructional video made the process easy to follow.
This modification completely transformed the bike and made it far more enjoyable to ride. I honestly don’t feel the need for any additional engine mods. I highly recommend the HITLIS system to anyone riding a YZ250 or YZ250X, especially for woods and trail riding.
