1961 Matchless G80 Typhoon


1961 MATCHLESS G80 TYPHOON BACKGROUND
Parent-company AMC knew how to build big singles. Despite now having a nice lineup of vertical twins, the real money was made selling Matchless and AJS singles. For Matchless, the top of the heap was the 500cc G80, and the best of those was the Typhoon. The AJS version was called the Model 18 and while styled slightly differently, was mechanically identical to it’s sister-bike with one exception: Matchless mounted its magneto in front of the cylinder and AJS mounted theirs behind.
