Description

Stock pistons can't handle the demands of high-performance riding, especially when you're pushing your Yamaha 660 to its limits. The WSM Piston Kit delivers OEM-quality construction with critical performance upgrades—superior ring groove hardening and MOS2 skirt coating—that reduce friction, manage heat more effectively, and add measurable horsepower and engine longevity. If you're rebuilding or upgrading your top-end, this is the precision component that separates a solid rebuild from one built to last.

  • Fitment: Yamaha 660 only
  • Oversized: +.50 mm
  • MOS2 coating reduces friction
  • Heat-dissipating skirt design
  • Hardened ring grooves
  • Includes piston, rings, pin, clips
  • One kit per cylinder
  • Improved E-clip design
  • Meets/exceeds OEM quality
  • Additional rings available separately
  • Bolt-on installation
  • MPN: 50-544-05K

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!
