chain sprocket 15 teeth 428 for Minarelli AM 53030

Chain sprocket 15 teeth, chain pitch 428 suitable for Minarelli AM engines. By changing the number of teeth on the front drive sprocket, you can influence the speed or acceleration. A higher number compared to the original usually means an increase in top speed and slightly lower acceleration if the rear sprocket remains unchanged. A lower number of teeth leads to more acceleration and reduced top speed. Even a difference of 1 to 2 teeth leads to significant changes.
