DescriptionProx Forged Piston kit

Product details :

Features

PROX Forged Piston – Manufacturer Ref. 01.2412.B

Designed for off-road competition, this PROX forged piston is made from a specific alloy to reduce friction and improve the reliability of the moving parts. Intended for cross displacements, it features a profile suitable for demanding high-rev use while maintaining standard compression.

Diameter: Ø 76.960 mm (76.96 mm)
Oversize: Letter B
Compression: Standard
Material: Forged aluminum
Delivery: kit (rings included)

The PROX piston is aimed at motocross riders looking for a robust wear part that can withstand the cyclic stresses of the cylinder and sleeve. Its finish and alloy minimize internal friction for better piston and ring endurance over time.

Main compatibilities (examples): YAMAHA YZ 250 F (CG33) 2012 – 2013 (250 cm3). Please check your engine specifications before installation to confirm the use of oversize B.
