Vintage Thing No.64.1 - Sunbeam Model 90
You've seen this side before Earlier this year I took the opportunity at Wiscombe Park to study the other side of this Sunbeam Model 90, which I spotted at last year's meet propped up against some Portaloos. But this was not the view I was expecting. According to my information a Model 90 should have a head like this. I really like the "architecture" of a single cylinder motorcycle engine But what was revealed was this. This Sunbeam looks fast despite the fairly high bars for hauling the bike round the bends but looks like it'll stop thanks to the nice big front brake. I know I should have spotted that it was a single port head even when looking at it in the rain from the drive side. I can only assume that this bike is powered by the later version of this engine, which would make it a Model 95. The trouble is, Sunbeam motorcycles of this era are rather obscure. Their best years were the vintage ones and post war everyone remembers them...
