Description
If you’re running a Yamaha YZ80 and want reliable top-end performance, a quality piston kit is non-negotiable. Wiseco’s 569M04950 delivers the precision engineering and durability needed for consistent power delivery, whether you’re pushing hard on the track or logging trail miles. This kit includes everything you need for a straightforward installation—no surprises, no missing components.
The 49.50mm bore is engineered to maximize combustion efficiency while the premium aluminum alloy construction resists the thermal stress and wear that comes with aggressive 2-stroke operation. You’ll notice improved throttle response and acceleration, the kind of gains that come from engineering done right rather than marketing hype.
