MOTOMASTER Moto Master Motorcycle Crown Offroad Fusion Series 520-51T in Hardened Steel and Aluminum Alloy

For more than 20 years Moto-Master has specialized in the production of braking and transmission components for the off-road world and is recognized by the market for its excellent quality and precision in the manufacture. The Moto-Master Fusion Dual-Ring crown offers the best of both worlds: special hardened nickel coated steel outer ring and 7075-T6 aircraft aluminum inner ring. These crowns last 3 times as long as an aluminum crown and weigh up to 50% less than a regular steel crown. Fusion crowns are CNC machined with minimal tolerances and made with the best material available for racing crowns. The rings are precisely made and are permanently joined using a thermal shrinkage technique for a solidarity union of the bodies. The inner ring also has a coloured anodized coating for durability.
