wakeup said:I'm pretty sure that the drawing I had a look at, for production featherbeds, had identical geometry for Manxes and road bikes. The geometry of the frame comparing year by year, was identical as far as I remember, apart from material and wall thickness, and a couple of brackets. Anyone familiar with the use of "variant" drawings would be at home with the concept. The basic geometry was shown on one sheet, with an applicability list, odds and sods brackets shown on another sheet with another applicability list and so on. Glad to be proven wrong though!
There were many, many different issue states of the basic featherbed frame all of which were applicable to a particular year or model. Different bikes were built to a Specification, which was pretty much the overall controlling document. The Spec detailed everything required to make and assemble any given bike. A fairly sensible early version of configuration control really, before the Configuration Control experts moved in.

So is that 'same geometry' ??'
I'd be interested to know how the Domiracer was set up and handled. The late fifties manxes seem to have been well optimized for the single cylinder motor and 19 inch wheels.

Only "production" racers were made after that? Until the final demise in '62 - '63.
