Product Description

The Renthal Ultralight Rear Sprocket is precision-machined to optimize power transfer while drastically minimizing unsprung weight on your Kawasaki or Suzuki dirt bike. Designed for off-road, dual-sport, adventure touring, and street applications, this 51-tooth black sprocket merges elite durability with high-performance weight reduction.
