JT SPROCKETS Sprocket - Rear - Yamaha - 38-Tooth JTR849.38

A worn or incorrect sprocket directly impacts your bike's acceleration, top speed, and engine efficiency. The JT Sprockets 38-tooth rear sprocket delivers the precision engineering and durability needed to maintain consistent power delivery without compromising longevity. Whether you're pushing hard on the track or logging miles on the street, this sprocket is engineered to handle sustained performance demands.

JT Sprockets uses computer-aided design to optimize tooth geometry for maximum strength while keeping rotational mass minimal—critical for responsive throttle response and reduced inertial losses. The C45 high-carbon steel construction combined with precision heat treatment ensures this sprocket resists wear, reduces chain wear, and maintains accurate engagement cycle after cycle.
