Description

When you're pushing your YZ250F to the limit, stock pistons won't cut it—you need a unit engineered for sustained high-RPM abuse. The Wossner 8614DA delivers the durability and reliability that separates winners from the rest, with German precision engineering and FEA-optimized geometry that translates directly to consistent power and longer engine life between rebuilds.

This complete kit gives you everything needed for a straightforward installation: piston, rings, wrist pin, and circlips. The 4032 T6 forged aluminum alloy paired with Wossner's proprietary permanent skirt coating reduces friction and piston rock, meaning quieter operation, faster throttle response, and measurable performance gains across the entire RPM range.

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!
