Upgrade your motorcycle’s final-drive system with the JT Sprockets JTR1842.55 rear sprocket, engineered for Yamaha applications. Computer-designed to deliver high strength with minimized weight, this 55-tooth sprocket combines precise manufacturing, quality materials, and dependable performance for riders who expect consistent power transfer and long-term durability.
Every JT Sprockets component meets or exceeds stringent quality standards established for the motorcycle industry. The JTR1842.55 is produced from premium C45 high-carbon steel, a material selected for its strength and resistance to wear under demanding riding conditions. Its carefully engineered tooth profile supports smooth chain engagement and helps promote reliable drivetrain operation.
The sprocket is heat-treated to enhance material hardness and service life, then bead blasted to help reduce surface tension created during manufacturing. This finishing process contributes to a durable surface designed to withstand the friction, load, and repeated impacts associated with street, off-road, and performance motorcycle use. The 55-tooth configuration can also help tailor final-drive gearing to suit specific riding preferences and application requirements.
