If you like British bikes from the 1960s then you'll appreciate what we have here, it's a 1966 BSA Spitfire and everything on it is original, no reproduction parts of any sort, the owner even has a reproduction seat grab rail, but decided he just couldn't do it.
The BSA Spitfire was a 650cc parallel twin with a 4 speed transmission. The engine had two overhead valves per cylinder and Amal carburetors. Drum brakes fore and aft and a great example of what British motorcycles of the day were supposed to be.
The owner states this was judged 99.5 by the AMCA (Antique Motorcycle Club of America) and the photos give no reason to believe otherwise. At 3284 miles, you're looking at a low mile unit that has been maintained in superb condition. This is a probably best owned by someone who is willing to put up with the eccentricities of British bikes, or, more than likely, is planning to build up his collection of fine British machinery. It's for sale on eBay.
