Description

JT Sprockets rear chain sprocket JTR486.42ZBK made of steel gearing — a British manufacturer with tradition since 1946. JT rear sprockets are CNC machined 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 = greater torque (better acceleration, lower top speed), fewer teeth = higher top speed (suitable for track and road use). Delivery time 7–14 days. SKU: JTR486.42ZBK.
