It is essential to make sure of the type of transmission you need before ordering. On small displacements we find mostly on the 50cc of the 420 (width 6 mm, center distance 12.7 mm) but some 50 and most 125 are equipped with 428 (width 7 mm, center distance 12.7 mm), even for the 125 in 520 (width 6 mm, center distance 15.8 mm). All the parts of the kit, namely the pinion, the chain and the crown, must imperatively be of the same type.
