Renthal Ultralight Rear Aluminum Sprocket Yamaha 125cc-400cc

Renthal chainwheels are chosen by more factory Motocross and Supercross teams than any other brand on the market today. Each sprocket is CNC machined to offer the greatest concentricity and optimum tooth profile for increased life and durability in the most rugged conditions. Through the CNC machining process, Renthal is able to create an extremely lightweight rear sprocket which reduces revolving unsprung weight and allows maximum power transfer to the rear wheel. The Renthal Ultralight Aluminium Sprocket was designed for the MX or Off-Road rider looking for maximum weight savings with excellent durability and performance.


  • Constructed from 7075 T6 aluminium alloy
  • Mud grooves prevent build up of mud, helping increase the working life of the sprocket
  • Optimized CNC machining allows maximum wight reduction while maintaining strength
  • Hard wearing anodized finish to prevent corrosion and color fade

Note: Images are for reference only, actual sprocket will vary based on make and model.
