Description
If you’re running a 2000-2003 Suzuki RM125 at the edge of its limits, a stock piston won’t cut it. The Wiseco 55mm Oversize (+1.00mm) Piston Kit delivers the compression ratio and durability needed to extract real power gains while maintaining reliability through sustained racing or aggressive trail riding. This is a direct path to noticeable horsepower and torque improvements without compromise.
The forged high-silicon aluminum construction resists detonation and thermal stress better than OEM alternatives, while the E-coated crown and ring grooves extend component life under high RPM operation. You’re getting a complete refresher kit that’s ready to install—no hunting for matching parts.
