Delivered as a kit to facilitate restoration during an engine overhaul.

Usage: Motocross / competition
Diameter: Ø 77.00 mm (C)
Compression: High compression
Material: Forged aluminum
Delivery: Piston kit (rings provided as per reference)
Manufacturer part number: W40151M07700C

Experienced riders will appreciate the finish and machining consistency that facilitate fitting to the bore. Ideal for those preparing an engine to regain performance out of corners or to handle high RPMs without surprises. Please check compatibility with your model before installation: this piston is notably suitable for several versions of YAMAHA YZ 250 F (CG34/CG39, 2016‑2018).
