Rear sprocket 428 45T D41mm

Rear sprocket 428, 45 teeth, D 41 mm – a toothed wheel on the rear hub. Together with the front sprocket and the chain it forms the final drive ratio: the tooth count decides whether the machine accelerates faster or reaches a higher top speed on the straight.

• Marking 428 – it must match the marking on your chain, otherwise the teeth will not match its pitch
• 45 teeth – the number from the name; it is not cast onto the sprocket itself
• The drawing measures only the mounting-hole spacings – 74 mm and 41 mm; the centre bore is not measured in it
• The disc has two rows of holes – the larger ones closer to the teeth, the smaller ones closer to the centre
• Replace all three parts together – a new chain wears quickly and stretches again on worn teeth
• The closest tooth counts in the 428 line in the list – 43 teeth (D 54 and D 64 mm) and 46 teeth (D 64 mm)
• You'll find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category
• Supplier code AT ZT42845 – quote it again when ordering

We write only what we know. The D 41 mm from the name is drawn between the mounting holes on the drawing, not across the centre bore, so we do not derive the bore size from it. Before ordering, copy the marking from your chain's side plate, count the teeth on your old sprocket, and measure the mounting-hole circle and the centre bore – we will check it before you order.
