Description

Stock cylinder limitations can compromise peak horsepower and throttle response on your KLX, DRZ, KFX, or LTZ400. The ATHENA Cylinder Kit delivers measurable gains through advanced materials and thermal engineering—larger water jackets keep temperatures in check while the forged piston with molybdenum coating handles increased combustion pressure. Best of all, installation is straightforward bolt-on work with zero machine shop trips required.

  • Aluminum cylinder body
  • Nickel-carbide coating
  • Enlarged water jackets
  • Forged piston design
  • Molybdenum piston coating
  • Complete gasket kit included
  • Bolt-on installation
  • No machining needed
  • Step-by-step instructions

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!
