Front sprocket 428 17T

Front sprocket 428, 17 teeth – the small sprocket on the engine shaft. It turns the fastest of the whole drivetrain and wears out first, so it is replaced together with the chain and the rear sprocket.

• Marking 428 – it must match your chain's marking, otherwise the teeth will not match its pitch
• 17 teeth – the drawing says "17 teeth"
• The chain marking is written out in words on the drawing: "428 chain"
• Central bore 17 mm with splines – they must match your engine shaft's splines
• 34 mm between the two retaining plate holes
• Replace all three parts together – on worn teeth a new chain wears out fast and stretches again
• The 428 front sprocket list has 13, 14, 15, 16 and 17 teeth; there is also a separate line with a 12 mm axle named in it – the 428 17T axle 12mm is a different product, not a variant of this one
• You will find other sprockets in the "Sprockets" category, and chains and their joining links in the "Chains" category
• Supplier code WI ZQ00231 – quote it if you reorder

To be straight with you: before ordering, copy the marking from your chain's plate, count the teeth on the old sprocket and measure the bolt-circle and the central bore – we will check it before you order.
