Description

The Renthal Twinring Rear Sprocket is designed for Yamaha YZ models (125, 250F/X, and 450F) from 2002 to 2023. Featuring a 49-tooth design, it combines a hardened steel outer ring with an ultralight aluminum inner for durability and reduced weight. The steel outer is heated to 200°C before being permanently bonded to the aluminum core, ensuring longevity without compromising performance. This dual-material construction provides increased wear resistance while maintaining lightweight characteristics, making it ideal for off-road and enduro riders looking for durability with minimal maintenance.
