Description
The ProX 0.50mm oversize kit for Yamaha 760/1200 corrects moderate cylinder wear where standard pistons run loose but bigger oversizes seem excessive. Cleans light scoring and taper while preserving wall thickness for future rebuilds. Engine builders love it for balancing cost, performance, and longevity.
- Precisely +0.50mm oversized piston kit with matched rings, chromoly wrist pin, double circlips
- Advanced low-friction alloy expands predictably from cold starts to redline
- CNC profiling delivers flawless ring grooves, skirt taper, dome geometry
- Calibrated for factory-spec clearances when cylinders hit exactly +0.50mm
Transform smoky, flat engines into hole-shot machines with clean pipes and strong pull. Thinner rings seal aggressively yet flex under heat cycles.
