Description

A top-end rebuild on your classic Big Twin demands pistons engineered for reliability and performance—and Wiseco's high-silicon aluminum construction delivers both. This complete kit eliminates the guesswork by including forged pistons, rings, wrist pins, circlips, and gaskets, so you can focus on the rebuild itself rather than sourcing components. Whether you're refreshing tired ring wear or stepping up to an overbore, you'll get the durability that's made Wiseco the choice of professional rebuilders and serious DIY mechanics alike.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

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!
