Description
If you’re pushing your RM 125 to the limit, a +2.00 mm oversized piston unlocks measurable gains in compression ratio and combustion efficiency—directly translating to stronger top-end pull and more consistent power delivery across the RPM band. Wiseco’s high-silicon aluminum construction handles the thermal and mechanical stress of competitive racing, while the E-coated internals resist wear far longer than OEM specs. For serious racers and tuners, this is the foundation of a reliable, high-output build.
