How to make a side stand for a C12
« on: August 30, 2015, 04:30:37 PM »
I got fed up with putting the bike onto the center stand every time I went out while I close the garage doors (the low life round here will empty your garage in seconds if you leave it open) I didn't fancy the idea of clamping something onto the frame tube, so I made a mounting plate from 1/4 inch plate with threaded holes so that it bolts behind the pillion footrest mounting replacing the two nuts that hold the mounting to the lugs on the frame.
I put a bend into the plate by cutting halfway though the thickness of the plate, bending it, and running a weld along the V shaped slot that opened up in the bending process.
I made the leg from solid bar on my lathe with a slight taper ( I hope the weight doesn't, slow the old girl down too much) but it could easily also be made from tubing if you haven't got a lathe.
Then it was just a matter of drilling and tapping for the spring mountings and making a clevis pin (but a nut and bolt would do for someone without access to a lathe)
The only thing I haven't yet done is made a foot to weld onto the end of the leg.







I've really enjoyed myself over the last couple of days, but now I've got to clear up the damn workshop.

Looks Good.

Do you need a foot on the end of the tube to stop it digging in on soft ground?

Now if you need another challenge. Could you see if you can modify it to easily fit a C10/11 Plunger/ridged frame?

Yes, I did say in my post, I still have to make a foot and weld it onto the leg, I have tried it on the bike and it fits perfectly but I need to wait for dry weather before I can try it properly and decide the exact length of the leg and the perfect angle to cut it off before welding a foot on.

I would have to look closely at plunger and rigid frames before I could design a modification, I have no intentions of going into production, this is just a sharing of ideas,

Foot fitted and the stand works perfectly, I have now also rounded off the sharp corner on the front of the plate (since the pictures were taken) I thought it looked better.

Now it just needs a final polish and a coat of paint.





If anyone decides to try making one I have one word of advise, when measuring make sure you check where the center stand is when the bike is not on it, I had to modify my spring as it just fouled the end of the center stand as the side stand was lowered.

I would just lacquer it to show off your handy work.

Looks a neat bit of handiwork Paul. It might be useful to others if you posted the approx. dimensions.

Here are some drawings of the stand, but I must stress that you check all the dimensions against your own bike as you go along, this worked fine for my bike, but other bikes might vary.

Once painted and fitted it looks as if has always been there.

One thing... (having just been working on a much longer Bultaco side stand). Wouldn't the drilled part of the leg become a weak spot? I just wondered if a brazed or welded on bit might be stronger? Perhaps if you use a decent gauge bit of tube it doesn't matter?

I'm having great fun trying to stop the one on my Bultaco from folding in half but at least I'm getting plenty of practice with the new TIG :-X

Maybe using tubing it may need reinforcing, using solid steel as I did , it is really strong, I have really tried to make it give way but it shows no signs of weakness.

I think the most important thing is to get hold of a bit of 5/8" tubing with a really substantial wall.

Most of the loading should be endways - I don't like to see a bike leaning sideways with a less than very shallow angle between its centre line and the side stand.

My Yam IT Enduro bike has a very long, light and slender tubular side stand and this gave no trouble at all for several years until my son started to use it. He wasn't tall enough to climb on without a good step-up and the stand soon got buggered up with his bouncing about on the kick start.

I just pieced and welded it all together again and it has given no more bother while being used correctly to just stand the bike upright at a decent angle.

That's an excellent bit of work, Paul, and the pleasure was in the making of it. It's been mentioned before that a Kawasaki ZZR 600, and other assorted models, is very easy to adapt to a C12 and will cost about a tenner if you don't have the skill, time or equipment to make one. The Indian-made replicas, for about £15, also work well on the rigid and plunger Cs.

Yes I agree, it's all about the" angle of the dangle" I found bending the mounting plate to 35 degrees worked very well and the loading is straight though the center of the leg, end to end.
