Rear sprocket JT JTR857.46 46T 520

JT Sprockets rear chain sprocket JTR857.46 made of steel toothing — a British manufacturer with a tradition since 1946. JT rear sprockets are CNC-milled with precise tooth geometry for smooth engagement with DID, RK, JT and other chains. Changing the number of teeth on the rear sprocket affects the character of the motorcycle: more teeth = higher torque (better acceleration, lower top speed), fewer teeth = higher top speed (suitable for track and road riding). Delivery time 7–14 days. SKU: JTR857.46.
