Description
The ProX Piston Kit for Kawasaki 800SXR 0.50 provides a popular half millimeter oversize choice when the cylinder needs more material removed than a 0.25 mm bore, but remains well within practical service limits. This size is frequently selected for skis that have seen harder use, repeated heat cycles, or light seizure events. With the correct machining and assembly, this kit can give a tired 800SXR a noticeably renewed punch on the water.
- 0.50 mm oversize piston kit designed for Kawasaki 800SXR engines requiring a moderate overbore.
- Kit contains oversize piston, ring pack, wrist pin, and circlips, working together as a matched set.
- Machined from low expansion, low friction alloy using modern CNC processes for consistent quality from unit to unit.

By refreshing the top end with this ProX kit, riders can reduce blow by, restore low end torque, and smooth out mid range power. It is a practical upgrade for freeriders, racers, or recreational users who want a reliable engine without stepping into extreme modifications. Ensure that cooling, fueling, and lubrication systems are working correctly to protect your investment in the rebuild.
Careful measurement of the finished bore, piston to wall clearance, and ring gaps is essential, as is following torque specifications and recommended assembly procedures. With the engine reassembled and broken in correctly, the ProX 0.50 mm oversize piston kit can help keep a Kawasaki 800SXR competitive and enjoyable for many more riding seasons.
