Description
If you’re pushing your TT-R125 hard on the trail or in competition, your stock piston won’t cut it. The Wiseco 4752M05400 delivers the strength and efficiency needed to handle sustained high-RPM abuse while maintaining reliability across both recreational and racing applications. This is a complete, ready-to-install solution that upgrades your engine’s core performance in one bolt-on refresh.
Built from premium high-silicon alloy, this piston resists detonation and thermal stress far better than cast alternatives. The 11:1 compression ratio optimizes power output for a 125cc four-stroke without requiring fuel octane upgrades, and the lightweight design reduces rotational inertia—translating to quicker throttle response and easier engine acceleration. Every component you need—rings and circlips included—means no hunting for compatibility parts or guessing on clearances.
