Description
If you’re running a Suzuki RM or Yamaha YZ two-stroke, your sprocket takes a beating every time you hit the track or trail. The Renthal 47-tooth rear sprocket cuts rotational mass by 66% compared to steel, translating directly to quicker acceleration and more responsive handling—critical advantages in competitive racing or technical terrain. Built from 7075-T6 aluminum with self-cleaning mud grooves and a corrosion-resistant finish, this is the sprocket engineered to outlast mud, dirt, and the demands of serious riders.
