§ 02 / About this part
What it is
The PROX PISTON KIT FORGED 76.97MM C, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged piston sits at the heart of your top-end rebuild. It replaces the factory unit to restore compression and engine response. Forged construction handles the higher thermal loads of race-pace riding better than cast alternatives. This C-size kit is designed for cylinders with slight wear to ensure precise skirt-to-wall clearance. It matches OEM cross-reference 1SM-11631-00 for a direct fit. Always measure your bore diameter with a micrometer before installation. Replace your top-end at the hour interval specified in your workshop manual to prevent skirt fatigue or ring failure.
