WISECO offers you a GP Series piston kit developed for HONDA CR 125 2-stroke engines used in intensive motocross and competition. This GP Series range takes the high-performance base of Pro-Lite pistons and adds advanced technologies designed for prolonged high-speed use and extreme conditions. Made from high-strength forged aluminum alloy, this piston features Electra-Coated treatment on the crown, ring grooves and pin seats to limit wear, micro-weldings and heat damage. Its ArmorGlide skirt coating reduces internal friction, improves lubrication and optimizes engine response to deliver more power and longer life. Thanks to its lightweight, reinforced design, it ensures rapid rev-up, excellent ring sealing and consistent performance even in intensive racing use. The kit typically includes forged piston, rings, pin and circlips for a complete, reliable top-end rebuild.
