Description
Stock pistons wear faster and limit your CRF250R’s potential—a quality replacement is essential for maintaining compression, power delivery, and engine longevity. The Wiseco 13.5:1 piston kit delivers measurable gains in throttle response and efficiency while the moly-coated skirts reduce friction wear during hard riding. Built from high-silicon aluminum alloy, this kit handles the demands of competitive and recreational use without compromise.
