Rear sprocket 428 40T D37mm fixed with cotter pins

Rear sprocket 428, 40 teeth, D 37 mm — a wheel with teeth on the rear hub. Together with the front sprocket and chain it forms the drive: the tooth count determines whether the vehicle accelerates faster or runs faster on the straight.

• Marking 428 — it must match the marking on your chain, otherwise the teeth won't match its pitch
• 40 teeth and 166 mm outer diameter — marked so in the drawing; cast on the part is "428 40T"
• Central bore Ø 37 mm — the drawing's arrow from this number points straight to the central bore
• Six Ø 8,5 mm mounting holes: 27 mm between adjacent ones, 55 mm between opposite ones
• Replace all three parts together — a new chain wears down fast on worn teeth and stretches again
• The list also has a second 428 sprocket with 40 teeth and the same 37 mm bore — its name doesn't mention the fixing method, while this one's name specifies cotter pins; check how your old one is holding up
• You'll find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category
• Supplier code WI ZQ7001B — quote it again when ordering

To be straight with you: before ordering, copy down the marking from your chain's plate, count the teeth on the old sprocket, and measure the mounting-hole circle and the central bore — we'll check before you order.
