We can supply sprocket platewheels (blank sprockets) in either dural or steel in most sizes. These are flat platewheels which have a small centre bore hole which can be machined. For dural sprockets we can offer a machining service. Some of the smaller steel sprockets can be supplied with a boss on one side.

For modern motorcycles we supply pattern sprockets. These are usually made by  JT or Renthal. Our prices are competitive. We specialise in sorting out sprockets and chains for 'specials' or where a change of gearing is desired. We don't just do pre-wrapped or ready boxed kits! - we do this ourselves, so it doesn't matter whether a non standard sprocket is needed. Just contact us for a quote.

We are often asked by our customers to provide information on the dimensions of various sizes of sprockets. So we have created some spreadsheets which we hope will be useful for those of you who are considering changing the number of teeth on your sprockets. Please bear in mind that the measurements provided in these tables are the overall diameters of the sprockets themselves and if clearance is an issue, you will also need to allow extra space for the chain
