Wiseco 4 Stroke Racer Elite Piston Kit, 97.00 MM Bore, 14:1 CR

The Wiseco RE825M09700 Racer Elite 4-Stroke Series Piston Kit is R&D developed to provide dyno-proven power gains. It features an asymmetric skirt design for improved wear and even loading on the major thrust skirt, a precision fit ring, and a custom-lapped compression ring for improved power. The piston is 100% billet machined for superior strength-to-weight ratio and optimized fit, with a high compression ratio (14:1 for 450cc) for maximum torque and throttle response. The dome design improves flame travel to maximize air/fuel burn efficiency. It also includes a DLC-coated piston pin to reduce friction and improve scuff resistance, enhanced pin oiling for improved lubrication, and a pressure seal groove to reduce ring lifting and power loss. ArmorGlide® skirt coating further reduces friction for quieter operation and improved scuff resistance. The kit includes rings, pin, and circlips.
