PROX Forged Piston (ref. 01.2409.C) — designed for motocross machines, this forged aluminum piston is machined from a specific alloy to minimize friction and ensure durability. Engineered to meet the demands of 250 cm3 displacements, it is suitable for riders looking for a robust and precise replacement part for their engine.
Compression: standard
Diameter: Ø 76.97 mm (Ø 76.970 mm)
Oversize letter: C
Material: aluminum, forged
Delivered with ring kit
The forging process provides a denser material structure than conventional machining, giving the piston good resistance to the mechanical and thermal stresses encountered in off-road conditions. The machining tolerances ensure a precise fit in the cylinder and contribute to good ring/cylinder contact right from the start.
Main compatibilities: YAMAHA YZ 250 F (CG33) 2013, YAMAHA YZ 250 F (CG27) 2009, YAMAHA YZ 250 F (CG33) 2012. Check the bore and oversize letter of your engine before ordering to ensure compatibility.
