Description

If you're running an 883cc or 1200cc Big Twin and want measurable power gains without a complete engine rebuild, this S&S piston kit delivers a straightforward path to 1250cc displacement and a meaningful bump in output. The 10.3:1 compression ratio strikes a balance between performance and reliability on pump fuel, while the cast flat-top design provides proven durability across thousands of miles. Pair these pistons with S&S CNC ported heads for optimal results, or run them with stock 1200cc heads if your budget doesn't allow it.

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!
