We specialize in restoring/rebuilding British motorcycles built between 1966 and 1974, primarily Triumphs, Nortons, and BSAs. We have relationship with several important suppliers of parts for British motorcycles:

We are a Burlen Authorized Dealer. Burlen is the parent of the The AMAL Carburettor Company and we are an AMAL Authorized Dealer.
We are a Tri-Spark Authorized Reseller
We stock lots of Andover Norton small parts and a few large parts.
We are a Wassell Authorized Dealer.
We are a reseller of Colorado Norton Works products.

We quit selling on eBay 6/21/21 but sell everything direct for less - just write us or look here!

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 NOS (New Old Stock) or original used parts wherever possible. For Norton, we usually buy new genuine Norton parts from Andover Norton since the fit is guaranteed and the prices are excellent. See the links at the left for some of our rebuilds/restores.

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. Now that we've installed a large blast cabinet, we can sand/bead blast most frames. It's not big enough for the oil in frame Triumph, or Norton frames, but all the two-part frames will fit.

Here are some of our projects. More projects and much more information are in our Norton and Triumph sections.
