sprocket Top Performances 14 tooth 428 for Minarelli AM

High-strength and low-wear chain sprocket from the tuning expert Top Performances, available in various ratios. By changing the number of teeth in the front drive sprocket, you can gear for either top end or acceleration. Increase the number of teeth compared to the original generally means an increase in the top end speed, but somewhat reduced acceleration [if the rear sprocket is unchanged]. A reduction in the number of teeth leads to greater acceleration and reduced top speed. A change of just 1 or 2 teeth leads to noticeable results . This 14T sprocket has 14 teeth and is used on a 428 standard division of the chain.
