About this item

A heavy-duty 40-tooth 420 chain sprocket built for mini bikes and go-karts running Predator 212cc/196cc/200cc engines. It has a 40mm center bore with dual mounting hole patterns (6-hole at 49mm and 4-hole at 80mm) so it drops onto a wide range of Coleman, Baja, Hensim, TrailMaster, Massimo, Motovox and Monster Moto models. The kit comes complete with both sprockets, two chain lengths, master links, hardware, a keyway and a chain breaker, so you can swap the whole drive setup without buying extra parts.

40-tooth 420 sprocket with a 40mm (1.57") center bore, machined with two hole patterns: 6 holes on a 49mm (1.93") circle and 4 holes on an 80mm (3.15") circle
