post war BSA four strokes

What information do you need to know ?
some on here might be able to help if you're more specific or just try google :D
 
I’ll post a couple of pictures as soon as I can get hold of a copier and learn to download the images…..meanwhile you may have seen the pictures of the bike a while back on the front page of Daily Mail weekend TV supplement of the TV chef Tony Martin :?:
 
My mistake, it is the chef James Martin, and the DM Weekend in question is 10 December 2016.
 
It has telescopic forks and an oval side cover at the bottom of the barrel .
 
S, I didn't realise it was a two stroke, but don't know if it is a C10, 11,12 :?:

The c10 was a 4stroke side valve , the c11 and c12 were 4stroke overhead valve engines , cheers
 
As far as I remember, BSA's only two-strokes were the 150cc Bantam (used by Post Office telegram deliverers) and a smaller 70cc bike. 250 and bigger were all 4-strokes.

The "BSA C10L" link I posted should have given you a strong clue as the C10 is a side valve 4-stroke. The C11 and C12 being OHV are noticeably different to the C10.

The Bantam started life as a 125cc and eventually grew into a 175cc.
