Rear sprocket JT JTR499.42 42T 530

JT Sprockets rear chain sprocket JTR499.42 made of steel tooth gearing — a British manufacturer with 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 = greater torque (better acceleration, lower top speed), fewer teeth = higher top speed (suitable for track and road use). Delivery time 7–14 days. SKU: JTR499.42.
