Do you have any record of a factory short stroke engine number not starting with 235xxx ?
Not so far, at least I don't remember anybody mentioning a non-235 numbered short-stroke engine before.

Based on the collective knowledge thus far, it appears likely a 1972 (ish) bike with a factory short stroke motor assembled and numbered most probably in the USA.
A lovely and unique bike well presented. Whether it is the "Missing Link" time will tell.
Danno said:What makes you think it's a '72?
Danno said:Don't recall ever seeing those cylinders before '74.
The few pics of the proposed short stroke road model that were shown didn't say 'short stroke',Danno said:and lettering on the sidepanels, which appears to be factory.

and the seller says 74.
Does anyone else see a problem here ?

so what is this statement based on ?
Be interesting to know what the NOC/factory records say about this 207000 number.
You'd think that that would have been checked on, and shown, for proof the sale bike was genuine.
If it had been sold on that basis, that is entirely a different matter ?Nortiboy said:Lovely bike and a worthy tribute to the factory short stroke that may have been.
There is also that minor matter of those 'matching numbers'Nortiboy said:Lovely bike and a worthy tribute to the factory short stroke that may have been.
Not according to my memory- the 850 look barrels came into the market in the 1980s as a reproduction from outside the factory. The factory didn't offer barrels as a spare at that time. We later bought the tooling which had not been used for a number of years and after overhaul and modification have since produced 750 and 850 barrels from it. The Peter Willams Monocoque replicas have our barrels (and a lot of other parts, naturally).The last 750 Commandos had the through bolted barrels that looked like the 850. The bore and stroke was as per standard 750 though. This one on ebay does look like the top barrel fin is close to the cylinder head though

Indeed the short strokes I have seen so far and that I have found in our (incomplete) recordes are 235xxx- I agree with L.A.B. there. That engine went into that frame somewhere outside the factory or was modified to short stroke.

The VMCC records department confirmed that 207000 was a black Roadster, date of manufacture, 24th May 1972.

At least the crank case numbers would suggest this. How relative is that, eh. What about the frame number, or the gearbox numbers?
