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 6mm, center distance 12.7mm) but some 50s and most 125s use the 428 (width 7mm, center distance 12.7mm) even for 125 in 520 (width 6mm, center distance 15.8mm). All drive train parts, i.e. front sprocket, chain and rear sprocket, absolutely must be of the same type.
