Description

The stock piston in your YZ80 is a wear item with a finite lifespan—especially if you're pushing harder on the track or trail. The Wiseco 520M04900 restores lost compression, responsiveness, and reliability while delivering measurable gains in mid-range torque and power delivery. This is a straightforward, bolt-in refresh that serious YZ80 riders choose when stock performance no longer cuts it.

Wiseco pistons are manufactured to tighter tolerances than OEM equivalents, which means better ring seal, cooler running temperatures, and longer service intervals between rebuilds. The forged aluminum construction resists detonation and thermal stress, making this kit the go-to choice for riders who demand consistency lap after lap.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
