Description
A rear sprocket is fundamental to your bike’s acceleration, top-end speed, and overall drivetrain efficiency. The JT Sprockets 51-tooth rear sprocket delivers the precise gear ratio tuning that separates competitive lap times from the rest, while its engineering minimizes unsprung rotating weight for sharper throttle response and better handling balance.
JT’s computer-optimized design achieves maximum strength without unnecessary mass—critical when every gram of rotating weight impacts your bike’s performance. Built from Japanese C45 high-carbon steel and subjected to heat treatment and beadblasting, this sprocket is engineered to meet the demands of track-focused riders and serious enthusiasts who refuse compromise on durability or precision.
