Piston Kit - Racer Elite - TRX450R/ER

R&D developed to provide dyno-proven power gains. Asymmetric skirt design for improved wear and even loading on major thrust skirt. Precision fit ring; custom-lapped compression ring for improved power. 100% billet machined for superior strength-to-weight ratio and optimized fit. High compression (14:1 for 450cc, 14.5:1 for 250cc) for maximum torque and throttle response. Dome design improves flame travel to maximize air/ fuel burn efficiency. DLC-coated piston pin reduces friction and improves scuff resistance. Enhanced pin oiling for improved lubrication and reduced friction. Pressure seal groove reduces ring lifting and power loss. ArmorGlide® skirt coating reduces friction for quieter operation, improved scuff resistance. Pistons include rings, pin, and circlips.
