Moose Racing Rear Sprocket - 50 Tooth - Yamaha 1211-853-50-11

• The 7075 T651 aluminum we use for these sprockets receives an extra tempering which reduces distortion and provides optimal thickness vs. typically thinner 7075 T6 sprockets
• 100% machined, no stamping or grinding
• Optimal tooth thickness results in maximum tooth and chain contact
