🛠️ Product Overview

Refresh your Yamaha 450-cc engine with Kibblewhite White Diamond™ stainless-steel intake, center-intake, and exhaust valves teamed with legendary KPMI® RED Viton® stem seals. EV8 one-piece stainless valves shed weight yet out-last OEM titanium, while the high-temp RED seals deliver leak-free reliability no matter how hard you ride.

  • KPMI RED Viton Valve-Stem Seals – 5 pcs, extreme-heat rated
  • Cometic Big Bore 98mm MLS Head Gasket – big bore friendly sealing
  • Direct OEM Replacement – swaps straight in for Yamaha OEM
  • All items brand-new, backed by KPMI & BPRATV warranty
Advantage What It Means for You
