JT Sprockets Rear Sprocket for Yamaha, 45-Tooth (JTR834.45)

Upgrade your Yamaha motorcycle’s final-drive system with the JT Sprockets JTR834.45 rear sprocket. Computer-designed for high strength with minimal weight, this 45-tooth sprocket combines precise engineering with durable materials to deliver dependable performance for street, touring, and off-road applications. Its carefully developed tooth profile supports smooth chain engagement and consistent power transfer.
JT Sprockets manufactures every sprocket to meet or exceed the highest quality standards in the motorcycle industry. The JTR834.45 is produced from premium C45 high-carbon steel, a material selected for its strength, wear resistance, and ability to withstand demanding drivetrain loads. This construction helps provide long service life when paired with a properly maintained chain and front sprocket.
The sprocket is heat-treated and bead blasted to reduce material surface tension and enhance durability. These finishing processes help the sprocket resist the effects of repeated acceleration, vibration, and regular riding conditions while maintaining reliable tooth performance. The 45-tooth configuration can also support a change in final-drive gearing, depending on the motorcycle’s original setup and the rider’s performance requirements.
