Need your order quickly? Please order on line - online orders are automated and save us a lot of time. We try to despatch all orders as quickly as possible but if your order is very urgent, please send us a message and we will do our best to send it quickly.

Orders by email or telephone take a lot longer as we have to input them manually.

Our office opening hours for telephone orders and technical help are Monday to Wednesday 9AM to 1PM UK time. (The telephone may not be answered outside of these hours). You can order online at any time or leave a message on our answerphone when the office is closed.

We are dedicated to keeping these wonderful machines on the road.

Our Sunbeam on-line parts catalogue is only a guide to the large stock of parts that we hold, or are in the process of manufacturing.... it does not list all the parts we keep. If you cannot find the part you are looking for please contact us.

We also have a huge stock of used parts so if you are looking for anything or if you can't see it in the catalogue contact us, we may be able to help! Like you, we are keen enthusiasts... any problems you have, please call us.

The original Sunbeam plate drawings are useful to see the parts and look up the numbers.
To identify most parts we use the plate number first, then the part number, then the description. Many parts we offer are not shown on the original plates including distributor and dynamo parts. These can be found listed in our Sunbeam parts catalogue pages. If you can't find what you are looking for, please use the search link at the bottom of the page. If you still can't find what you need, send us a message - we probably have it. The quickest and best way to get in touch is to use the contact link below.

Other services that we offer are: A full (free!!) technical advice service, issuing dating certificates, DVLA original registration number retention, etc. In fact, for everything connected with S7 and S8 'Beams we are the people. We are the major source of Sunbeam spare parts in the world and every part is made by us or specially for us. We endeavour to keep the spares stock ample and as inexpensive as we can. Obviously items that are cast involving moulds, need intricate machining, or are low volume will come out more expensive than items that are simpler to manufacture.

We very much look forward to hearing from you and hope that you enjoy perusing and regularly revisiting our web site. Remember, here at Stewart Engineering we are dedicated solely to those superb Classic British Motorcycles, the S7 and S8 Sunbeams.


We have a limited stock of very rare new and used early S7 parts available. These include chain tensioner, footrest, handlebar and other parts. If you are looking for something, please contact us and we will have a look in the Sunbeam "Aladdin's Cave".
