It is essential that you you check the type of drive train you need before ordering. On small motorcycles, most 50cc use the 420 (width 6 mm, center distance 12.7 mm) but some 50s and most 125s use the 428 (width 7 mm, center distance 12.7 mm) even for 125 in 520 (width 6 mm, center distance 15.8 mm). All drive train parts, i.e. front sprocket, chain and rear sprocket, absolutely must be of the same type.
