Welcome to BSA Unit Singles LLC

 

BSA Unit Singles LLC endeavors to be your single-source provider of parts, accessories, literature and help for the C15, B40, C25, B25,T25, B44 and B50 BSA models. This focus has allowed us to concentrate our resources to increase the probability of our customers finding more items related to these bikes in one place. Various UK suppliers have extensive parts holdings for these models but in the USA and the rest of the world, until now, it has been much harder to find suppliers who stock as wide a range of parts as we have developed at BSA Unit Singles.

 

We aim to supply you with all of the spare parts and accessories you need to service your BSA unit single, (two stroke Bantams excepted)and Triumph cousin the TR25W and T25. We stock a mix of quality new replacement parts, new old stock parts, and good condition used parts. We have 1500 BSA part numbers of active inventory on hand relating strictly to the unit single line from 1959 to 1973. Additionally we stock many different accessory items (non BSA part numbers) that are commonly used with these models. Use our category lists and search function to determine availability and pricing. One can search by part numbers or by key words.

 

On this website you can order spares from our secure online shop. Our ordering process is tied into inventory control so if an item appears as in stock it can be ordered at the price listed and is available. Follow-up phone calls are not needed to check to see if a part is really available or if the pricing is correct. The process for international orders is not quite as smooth. Orders can be submitted but final billing will not take place until the correct shipping cost is determined. Customers will be contacted with the final price including shipping to receive authorization to finalize the purchase.

 

Our mission is twofold:

 

The first and most important is to provide quality parts and supplies at competitive prices combined with a fast and accurate mail order service to satisfy the needs of our customers. We will work to continually to expand our product range in this specialty niche.

 

The second, which is funded by the first, is to provide a resource for BSA unit single enthusiasts with scans of BSA official publications available for free download. There are three categories. One with an exhaustive listing of scanned spares manuals. Another with scans of official BSA workshop manuals and owners books. The last contains interesting scans of BSA brochures and advertisements. These archives are one of the most extensive and thorough treatments of BSA unit single literature found anywhere on the web.
