It is essential that you you check the type of drive train you need before ordering. On small motorcycles, most 50cc use the 420 (6mm width, 12.7mm pitch) but some 50s and most 125s use the 428 (7mm width, 12.7mm pitch) even for 125 in 520 (6mm width, 15.8mm pitch). All drive train parts, i.e. front sprocket, chain and rear sprocket, absolutely must be of the same type.
Compatibility models for guidance, it is advisable to disassemble the part to be replaced beforehand and check the correspondence with pictures and dimensions indicated on the site.
