Features
R&D developed to provide dyno-proven power gainsAsymmetric skirt design for improved wear and even loading on major thrust skirtPrecision fit ring; custom-lapped compression ring for improved power100% billet machined for superior strength-to-weight ratio and optimized fitHigh compression (14:1 for 450cc, 14.5:1 for 250cc) for maximum torque and throttle responseDome design improves flame travel to maximize air/ fuel burn efficiencyDLC-coated piston pin reduces friction and improves scuff resistanceEnhanced pin oiling for improved lubrication and reduced frictionPressure seal groove reduces ring lifting and power lossArmorGlide® skirt coating reduces friction for quieter operation, improved scuff resistancePistons include rings, pin, and circlipsSpecs
