Description

The Wiseco 646M04800 is a Pro-Lite piston kit designed for Yamaha YZ80 models. This piston set features a 1.00mm oversize bore, bringing the actual bore to 48.00mm from a standard 47.00mm. It is engineered for durability and performance in 2-stroke engines.

Constructed from high silicon, low expansion aluminum, this piston offers superior strength and reduced weight. The diamond-turned finish, achieved through CNC computer-controlled turning, ensures a perfect finish with no size variation. This kit is intended for reliable, all-purpose riding on both track and trail.
