Barr and Stroud mystery bike
« on: January 10, 2018, 09:15:13 PM »
Who can help identify this machine?  Not much is known; it's a Czech registration, a photo taken in Czech.  Electric lighting and the overall style suggest late twenties or early thirties, but the 500cc Barr and Stroud sleeve valve engine is from 1924.  There is a name on the tank, just not enough that I can read.

Very stylish looking bike - that front guard is quite distinctive on it own.
Quite a lot of brakes for 1924 too, although could be from a later year, and earlier engine.

Didn't you have the production records for B&S, or was that just part of them ?

I have the sales records for B&S, and from that have extracted a fairly complete record of engine production.  It's not 100%, however.

Two 500cc engines were sent to Prague.  The photo is of a Czech bike, taken in Czech, so might be the destiny of one engine.....

Frame and overall style looks like a OEC of about 1926 to me.

Hi Helmut and All,
I thought OEC at first look, front lower of the frame and centre stand being similar
BUT
The the drive chain is not on the "correct" side for a British bike ??? they are almost always on the left side

If only that photo was a bit clearer, the name on the tank is nearly readable till the pixels lose it.

Obviously a pillion rider in those shoes!

The gearbox is a crossover type; the input is on the left, output on the right, yet it has a kickstart so is obviously a purpose made motorcycle gearbox.  A Hurth?

The frame has hints of Praga and ABC about it, but only hints, and the centre stand is really unusual for that era.

Looks like an Enfield rear sprocket, hence an Enfield wheel in "backwards".

Headlight arrangement and mounting is quite French of the era.

Of course there is no obligation for a Czech registered bike to have been made in Czechoslovakia?
