§ 02 / About this part
What it is
The PROX PISTON KIT ALUMINUM 98.00MM +1.00MM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This oversize piston kit is for engines requiring a 1.00mm overbore. It cross-references with OEM part 13101-MN1-680. Use this when your cylinder bore is damaged or worn beyond standard limits. It sits at the heart of the top-end and restores the seal between the combustion chamber and the crankcase. The kit includes rings, pin, and clips. Your cylinder must be bored and honed to 98.00mm to accept this fitment. Verify the piston-to-wall clearance during the machining process. Ensure the arrow on the crown points toward the exhaust port during your rebuild.
