Is my Commando a Mk1, 2, 3, 4???

According to the History section and model breakdown on this site, your model is a 1972 Commando Roadster Mk. V. This version was produced from January 1972, which fits in well with the production date stated by yourself. This is also in line with my own Roadster Mk. V with engine no. 211XXX. (X'es just because I don't recall the last 3 digits!).

Hope you find a seat!

Thanks Tom, much appreciated. I suspect the engine and frame were from a factory run in 1972 and used to make an Interpol. I do know that the bike left the factory on March 27th 1972 and was supplied to the Lancashire Constabulary. For my purposes I'll call it a MkV. I intend to make it an Interstate but hope to eventually have a Roadster tank and side panels as well so that I can alter the look when my mood dictates!

Yes, I on the other hand Ilike the fat Interstate tank, but they are hard to come by at realistic prizes. One was just sold on eBay for nearly £400 in a very battered and rough condition. Tom

Andy, the system of allocating 'mark' numbers to Commandos began in a bit of a haphazard way and was applied in some cases retrospectively. It was also applied initially to the different trim levels rather than the build year so Roadsters were at a higher mark than Interstates at one time. You need to be careful to watch the distinction between 750 and 850 models.

When most owners talk of a 'Mk3', they mean the 850 Mk3 Electric Tart which had a hinged seat. Although there were detail differences from year to year, any 'pronged' seat will fit your frame.

Broadly speaking, if you're ordering spares then the general convention is that MkIV 750s began at 200000 - these were the first models with the breather low at the back of the engine rather than on the end of the cam. They ran for most of 1972 and had the polished clockholders and small rear lights.

The MkV 750 had a similar look to the 850s - square tail light and long black clock holders. Whilst having the same engine breather system, there was no longer a steel blanking plate covering the old distributor / experimental starter drive mounting - the casting had no opening there. However, these cases were supplied as factory replacements for the earlier models so could have been swapped.
