Description

When your TT-R125's original pistons wear out, a quality rebuild kit is the difference between a restored engine and a costly failure. Wiseco's forged piston kit delivers the durability and thermal stability you need for consistent performance, whether you're running stock or modified power levels. This complete kit eliminates guesswork by including everything required for a proper top-end rebuild in one box.

The high-silicone forged construction resists thermal expansion, meaning tighter tolerances and better ring sealing even under sustained load. You get factory-engineered fitment for the TT-R125, reliable cold-start characteristics, and the confidence that comes with using OEM-matched components. Installation is straightforward for anyone with basic engine work experience, though professional machining of the cylinder may be required depending on its current condition.

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
