I've seen that Debenham Vincent in action, that was awesome.
Closest I'll ever be to a Norvin.
My guzzi never changed lanes on me when I didn't expect it.
Or even if I thought it might...
Eric Debenham and the Norvin - the most motor in the least frame you can achieve.
( I half expected one in the Brisbane GOMA motorcycle exhibition, but not so).
(they did have Jack Ehrets Black Lightning)
