We specialize in restoring and rebuilding British motorcycles built between 1966 and 1974, primarily Triumphs, Nortons, and BSAs. We have relationships with several important suppliers of parts for British motorcycles:
  • We are a Burlen Authorized Dealer. Burlen is the parent of The AMAL Carburettor Company, and we are an AMAL Authorized Dealer. Since the tariffs on UK purchases are now 10% rather than the previous 25%, we have almost all Norton Premier carb packs back in stock.
  • We are a Tri-Spark Authorized Reseller and keep most parts people want in stock.
  • We have a “Trade” account with Andover Norton and have well over $50k of their parts in stock.
  • We are a Wassell Authorized Dealer. They have many quality products, and we know which are good and which to avoid.
  • We are an RGM Authorized Dealer, but they are having significant problems right now, so we’re having trouble getting what we need from them.
  • We are a reseller of Colorado Norton Works products.
We quit selling on eBay on 6/21/21 but sell everything direct for less. Just write or call us, or see Parts for Sale to request a quote.

At any given time, we are restoring or rebuilding several bikes. We don’t do them one at a time because finding parts can take time, and often the parts need to be refurbished. Even though most parts for the more popular bikes can be purchased new (reproductions), we try to use original used parts wherever possible. For Norton, we usually buy new genuine Norton parts from Andover Norton since the fit is guaranteed. Andover Norton’s Triumph division is becoming an excellent resource for new Triumph parts as well.

We can do a complete restore or rebuild for you, or any part you like. For instance, some customers want us to do the engine and they do the rest.

Feel free to write or call us for free advice on Vintage British Motorcycles. We don’t know them all by any means, but on the ones we specialize in, we can help!

We have a large blast cabinet and can blast most parts in-house. We can also powder coat small parts in-house.

Since we started keeping track on June 1, 2017, we have completed 46 projects and currently have 36 more in the project list. Many of the completed projects can be found in the various “Home” pages at the left.
