Description

Renthal Ultralight rear sprockets are chosen by more factory motocross and Supercross teams than any other on the market. Renthal's rear sprockets are CNC machined to offer the greatest concentricity and optimum tooth profile for increased life and durability of both sprocket and chain. Through the CNC machining process, Renthal is able to create an extremely lightweight rear sprocket which reduces rotating mass and unsprung weight which increases power transfer to the rear wheel and better bike control as your suspension doesn't have to work as hard to keep the rear wheel in contact with the ground.

Features

  • Self-cleaning mud groove between each tooth help prevent dirt build up and consequently increase the life of your chain.
  • Sprockets are 65% lighter than most standard sprockets.
  • Specially enhanced high strength 7075 T6 aluminum alloy provides excellent longevity.
  • Computer aided Ultralight design further reduces rotating mass over standard sprockets to maximize power output at the wheel.
  • Fits the following models:
  • RAPTOR 350 04-09
  • YFZ-450 04-09
  • RAPTOR 700 06-09
  • Please Note: The image displayed is representative of the item, but may vary slightly depending on your specific model.
