Wiseco Piston Kit 48.5mm Bore for 1993-2003 Honda XR80R PK1226

When a 2-stroke engine is running on a worn or damaged piston, you're losing power, efficiency, and reliability on every ride. The Wiseco PK1226 restores your XR80R to peak performance with OEM-quality components engineered to handle the demands of competitive racing and aggressive trail riding. This complete rebuild kit gives you everything needed for a professional-grade installation without the shop labor costs.

The 48.50mm bore diameter is precision-machined to exact tolerances, ensuring a tight fit that eliminates ring blow-by and maximizes combustion efficiency. At 9.7:1 compression ratio, you'll see measurable gains in throttle response and mid-range power delivery—the sweet spot for both racing and recreational use. Wiseco's forged aluminum construction keeps weight minimal while delivering the durability to survive sustained high-RPM operation and the temperature extremes of off-road riding.
