Description

Engine reliability directly impacts race day performance, and a compromised top end gasket kit can cost you valuable track time or worse—a DNF. The ATHENA Top End Gasket Kit (P400485600254) is engineered specifically for Yamaha platforms and lets you optimize your engine's compression strategy: run pump gas with stock compression for reliability, or step up to race fuel and elevated compression for maximum power when conditions demand it. This is essential maintenance for pro, semi-pro, and amateur riders who want to freshen their top end before a season-opener or midseason rebuild without guessing games.

  • Yamaha-specific fitment
  • Stock or high-compression options
  • Standard or race-fuel compatible
  • Bolt-on installation
  • Excludes valve stem seals
  • Excludes rubber components
  • Excludes shims or fiber gaskets
  • OEM-quality construction
  • Pre-race or midseason refresh

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!
