C15 S Scrambler 1959 model. Side stand query
« on: 28 January, 2018, 19:48:27 »
Does anyone have a c15s 1959 scrambler? I am missing a side stand and have tried a 10.5 inch one from a B25 but it isn't long enough. The bike has the standard 19 inch rear and 20 inch front wheels, did BSA have a longer stand for this model?

I've tried to find an answer to your question but can't find any evidence that they were ever fitted with a side stand. I think that, unlike the C15T, the C15S was only ever intended for off road use and the use of a paddock stand would have been assumed. That said, I'm sure it wouldn't be too difficult to extend a standard side stand to give you the correct length.

There is a side stand shown in the 1959 catalogue for the competition C15 but no indication of its length.

The RH side stand used on the C15S appears to be 40-6047. One is advertised below and it might be worth phoning them to find out its length, although it doesn't look that long:

I've just found out a bit more info on the RH sidestand and it looks to be the same length as a standard C15. I suspect it's ok for a C15T but is not long enough for a C15S with its bigger wheels.

The only other thing that comes to mind to explain your difficulty with the side stand is: what is the length of your rear shocks? They should be a little over 11" in length but if yours are much longer then you would need a longer sidestand to compensate.

Thanks for the replies. The frame does have a mount for a side stand so I'm assuming the bike had one but that may not be the case. The parts book that covers the C15S start at 1960 models and lists the 404737 part number, I would think that 59 models would be the same but when I tried a 10.5" stand the bike lent too far over. I have standard repro girling shocks on the back and standard forks, wheels + tyres.
I would think the stand needs to be a couple of inches longer or maybe the bike was not fitted with a stand when new and the mount is just the standard C15 angle which is causing the problem with the added height of the bike. If the angle of the mount was changed to be more vertical I think a 10.5" stand would be ok but I don't really want the frame altered.

My standard C15 with 17" wheels and a 10" sidestand is fine. However, my standard B40 with 18" wheels and the same sidestand ideally needs a block of wood under it give it a good lean angle but just about works without it. The earlier C15T with 18" rear wheel and its RH sidestand of similar length to the standard sidestand will also just about work. However, your earlier C15S with a 20"/19" wheel combination is never going to work without a block of wood under the sidestand.

Thanks yes, a block of wood might have to be the low tech solution that I need. Hopefully it will fit under the side cover, I just need to find the correct side cover with a cut out for the air pipe. Every solution seems to create a new problem! I supposedly have a supplier that has a correct side cover but I'm waiting for him to unearth it. He did come up with a centre panel so fingers crossed on the side cover.

If it was my C15S, I would definitely think in terms of taking the proper sidestand, sawing it in half about 2" from the foot and then welding in an additional length to make it up to 2" longer. The only thing that would need to be checked is if it would still fold away safely when not in use. Carrying a block of wood around is not ideal especially on a scrambler!

According to Girling lists there were 2 different length rear units for the C15S;

1960 -1962 extended length 11.4 inches compressed length 8.8 inches.

1963 on extended 12.9 inches compressed 10 inches.

The long units on your frame would cause side stand issues.

The correct part number should be 40-4737 for the RH sidestand as shown in RR. Unfortunately, the sidestand shown as 40-4737 in the BBB link above is wrong - it is a LH sidestand. They haven't got the RH sidestand in stock.
