Rear sprocket 428 42T D76mm

Rear sprocket 428, 42 teeth, D 76 mm – a toothed wheel on the rear hub. Together with the front sprocket and the chain it makes up the gearing: the tooth count decides whether the machine accelerates faster or goes faster on the straight.

• Marking 428 – it must match the marking on your chain, otherwise the teeth will not fit its pitch
• 42 teeth – marked "T42" on the drawing
• Centre bore 76 mm – the drawing's arrow is drawn across the middle bore
• Thickness 6,6 mm – a separate side-view drawing
• Mounting-hole spacings on the drawing – 66 mm and 72 mm
• Triangular and elongated lightening holes in the disc, painted black
• Replace all three parts together – on worn teeth a new chain wears out fast and stretches again
• With the same 428 pitch and 42 teeth, the listing also has two more sprockets – D 58 mm and D 102 mm; the teeth are the same, only the centre measurement differs
• You will find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category

We write only what we know. The same drawing states the outer diameter as 152 mm, while the drawing for the sprocket of the same marking and the same tooth count in our catalogue shows 175 mm. Which figure is correct, we are asking the maker. Before ordering, copy the marking off your chain's side plate, count the teeth on the old sprocket and measure the mounting-hole circle and the centre bore – we will check it before you order.
