PBR steel C45 sprocket, designed for 428 transmissions and intended for motocross practices. PBR leverages its competition experience to offer reliable drivetrain parts that are suited for off-road conditions: the tooth profile is machined to ensure a stable fit on the sprocket carrier and a clean connection with the gears and chain.
This sprocket is aimed at motocross riders looking for a robust replacement part for their 428 chain. Its black finish facilitates aesthetic integration on off-road motorcycles, while the 47-tooth configuration allows for adjusting the gear ratio to favor acceleration or top speed depending on your setup.
Common application examples: KTM 85 SX STD WHEELS 17/14 (2025), HUSQVARNA TC 85 BIG WHEELS 19/16 (2025), GAS GAS MC 85 19/16 (2025). Check the number of teeth and the 428 pitch before installation to ensure compatibility with your gear and chain.
