Ultimate Yamaha YZ125: Testing the revised 2024 GYTR performance kit on the latest year two-stroke

Yamaha isn't resting on its laurels when it comes to the YZ125 two-stroke as the bolt-on GYTR engine kit has been revised for even more power and reliability.
MotoHead's Dave Willet, owner of the 2023 Yamaha fitted with the current GYTR kit, puts the new version through its paces on an awesome track.

If you really want to unlock the full potential from your small bore, yz125, install a Stic Super X carb. I did on my 2023 yz125x it totally transformed the bike from off idle to over rev. It is so smooth,strong, and has such a wide power curve now. People who ride it think it is a 150! At only 1/4 throttle with the X carb, it was almost as powerful as the factory dialed in keihin at full throttle.
I have since added a TSP cylinder head, Pro circuit pipe with a 304 silencer, TSP ignition module and a Yz125 powervalve governor spring. The horse power gains from those were significantly less than what the Super X provided alone. The X is a game changer for small bore bikes.
