Hi! Everyone, I m new to this board, from India, I just brought a 250 CC BSA recently and after looking at some pictures, its seems that the model is a C12. I need your expert advice on the following :
1. Is this indeed a C12 or some other model?
2. Where can I get some pictures for a Single Seat ( Saddle type) So that I can get it fabricated in India. It would be very expensive for me to import it, besides im not sure if I can import such things at all
3. Same for the rear mudgard. Need to replace this one.
Waiting to hear from all fellow BSA Riders LEt me know if there is sometime I can help u with
It may be a C12 motor, but its a C11 frame, C12s were swingarm, the one in the pic is a plunger frame, and the motor could be a side valve C10 its hard to say. Check the crank cases for numbers. Cheers Pod

Hi there, I agree with Pod, the bike in the picture looks like a sidevalve C10L to me. If you can locate the frame & engine numbers and put them on the board for us we should be able to determine the exact year and model. You will then have a basis to work from. I believe that there are quite a lot of BSA second hand parts available in India if you know where to look for them. What part of India are you from? Beezageezauk.

That's definitely a C10L which is a sidevalve (flat head) motor. It has an alternator in the primary case instead of a generator which puts it in the early fifties, probably about 1953. pod's advice is best. The engine numbers are on the left below the cylinder, and the frame numbers are on the left of the head stock, just in front of the tank. The solo seat you want was fitted to several models and is not a BSA specific seat, a Lycette I think. Here's a picture of the seat on a 1951 C11:
Note the different bottom end on this bike with a generator drive chain case, and the different top end which is the C11/C12 type overhead valve.

hi ger, thanks for the links, I did check them out, and as kev mentioned, I can find local made sprung seats, but i m not very happy with the way the look. But if i dont find a old one lying here some where , I would probably buy those local made ones.
its the same with rear guard too, there are some local RE ones, but then may require some mods before i can use them.
I am a bit confused now , the motor is indeed a side value. The frame number is dc 1051683 and enginer number is bc 1048941. the owner and the registration book says its a 56 model.
beezgeezauk, yes geting parts in india is relatively cheap and easy, but i m from a small town in west, so i have to go to north or bigger cities in west like mumbai to get them.
hh & ger, thanks for the pic, i did find it from my pervious searchs on google.
thanks for all ur help

I would say that your registration book is correct and your bike is a 1956 C10L. The frame numbers for this year were from DC10S-101 to DC10S- 2573 and the engine numbers were BC10L-7001 to BC10L-9611. So allowing for a slight mis-interpretation of certain letters and numbers it appears to be a genuine bike and probably still has its original engine.
The "5" in your frame number should be a "S" and the "4" in your engine number should be a "L". This happens quite often and is nothing to worry about. My "B31" is registered as a "S31" and BSA never produced a S31.
Good luck with the project and keep us informed of your progress.

It is always difficult to value any machine because there are so many variations to be taken into consideration. These variations will depend on the condition of the bike, or the quality of the rebuild or even where the machine is located. All I can say is the humble C10L will not command a particularly high figure so don't let it run away with your money. BTW, I believe that the rear mudguard on this model is the same as the Plunger 125cc Bantam so at least your search for that item should not be too difficult. Also the dual seat is correct for the 1956 C10L. I know of a couple more guys in India who run BSA's, but not in your area. If I can find their personal information I will pass it on to you privately. They may be able to suggest suppliers of second hand parts. Beezageezauk.

Try this for a C10 with single saddle Pics of my bike on BSAOC East Sussex Website which I run. http://email@example.com/c10 pics shown are of a C11 or C12 as these pic show rocker covers for an OHV arrangement, a C10 or C10L sidevalve, almost looks like a 2 stroke engine and head definatly looks like a two strokes head. Easiest way to check is , if you can remove the head by simply removing the 4 head bolts without any rockers, valve etc, then it is a sidevalve. Hope this helps
