Description

If you're serious about maximizing your YFZ450's power output and reliability, a quality piston kit is non-negotiable. Wiseco's forged-aluminum construction handles sustained high RPM and boost pressures that stock pistons simply cannot endure, while the 11.4:1 compression ratio delivers measurable gains in throttle response and peak horsepower. This is the kind of foundational upgrade that separates a weekend warrior build from a legitimate performance machine.

  • Forged aluminum construction
  • 11.4:1 compression ratio
