Rear sprocket 530 45T D129mm

Rear sprocket 530, 45 teeth, D 129 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 530 – it must match the marking on your chain, otherwise the teeth will not match its pitch
• 45 teeth – the number from the name; the drawing marks a 240 mm outer diameter
• Four mounting holes on four lugs: 129 mm between opposite ones, 91 mm between adjacent ones
• The centre is open – there is no continuous centre bore with a rim here, the sprocket sits only on the four lugs
• Replace all three parts together – a new chain wears quickly and stretches again on worn teeth
• This is the only rear sprocket for a 530 chain in the list; the 520 line has 32 and 36 teeth, the 428 line – from 37 to 52 teeth
• You'll find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category
• Supplier code WI ZQE7001 – quote it again when ordering

To be straight with you: in the drawing, the D 129 mm from the name is measured between opposite mounting holes, not across the bore – in ten other drawings of this line the same D leads to the centre bore, and in three products it is not explained at all, so note the difference here and measure it yourself. 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.
