Side Stand Questions

Hey, I have a 1981 BMW R100RS project that I'm working on and I had a few questions on the side stand. Right now this one is on it which was bolted to the rear engine mount and a band clamp around the muffler.



However, I'm changing up the exhaust and I don't believe that will work for me. I noticed that there is this bracket welded to the frame which I'm fairly certain is for the factory side stand.



So what I'm wondering is:

Am I correct in assuming that this bracket is for the factory side stand?
If so I also assume that ordering the side stand from the microfiche would give me the correct one? Probably looks something like this -


Lastly, out of curiosity, I've noticed that a lot of airheads I see use an aftermarket side stand. What is the reason for this?

Thank you so much for your help!

Because many of us find the OEM sidestand nearly unreachable while in the saddle, increasing the probability of dropping the bike.

The bottom picture shows the side stand that hangs from my frame, so I reckon you will end up with something similar...

You are correct about where it will attach to. Note the threaded ball in the bracket? Pop it out and put it to one side, the stand pivots on it and bolts through it so it's worth not losing it...

Not sure how effective the factory stand is, I intend to give it a go before changing to something more exotic...

Good luck with the project.

Not that familiar with the stock stand on your bike. Looks like a brown aftermarket stand. Good stand, lots of folks like it. But while your down there, check into your center stand. It is overextended, as in too far forward. You may need new bushings or the mounts may be "ovaled" out.

You've got a Brown's sidestand. Much much better than the factory sidestand.

Have you checked stock sidestand prices?

46 53 1 241 598 SIDE STAND $152.93
46 52 1 241 597 SHACKLE $16.75

BTW, it looks like the centerstand has bent/worn stops in it-- it pivots way too much forward. Makes it a PITA to get it off the stand.

Motobins has an improved side stand #91602 for your bike. I bought one years ago and its fine. The center stands for the 81's were designed wrong.

The stock stands have mixed reviews, general pro by tall folks and con by short folks. I like mine.

To use the Brown's Sidestand w/ a different exhaust you can prolly fabricate some manner of sub-bracket that fits between the front and rear engine mounts (or the rear engine mount and the stock s'stand bracket) out of 1" or 1-1/4" x 1/8" steel and bolt the sidestand to it. There isn't a lot of twisting on the sidestand so the sub-bracket doesn't need to be heavy. The Brown's is worth it, and you already have it...

There is clever engineering in that little olive set up in the oe side stand mount.
This olive allows the side stand to pivot up and down, when in the fully deployed position.
This in turn, allows the side stand to retract when someone is so !uckin stupid as to ride off with the side stand down.
I've done it ten times at least.

I've asked before what happens when someone rides off with their Browns/Surefoot/whatever sidestand in the deployed position.
I'm thinking they would tend to dig in and kick that rear end in the air?
And what about going to work in the twisties, do the Browns/Surefoot scrape easy?
The area that wears most on an 81 oe side stand is between the 'legs' at the top of the stand and is rather difficult to get at with a tig or mig to refill the worn areas and then machine. not really a viable repair imo.

But making a new one at work might be a bit o' fun.
Just a little bit freakin' longer than the oe one.

I have a service bulletin from 1990 Side stand repair for 81-84 models.

(I just looked up the part numbers in the bulletin, it includes a new side stand and the parts to fix it...you got to be kidding me. BUT my bulletin may help someone else fix theirs if they can fab the bushings etc.)

Let me be the first to offer to buy the Brown from you if you don't use it.

I can always use a spare...

So..that infers that you have a browns on your mono now. Is it a bolt up fit or do I recall some engineering involved?

Yes, it's on there now, works great, bolt right on.

Only thing is that the mono has a wider center stand, so if you just use the CS, sometimes you have to tag the Brown to allow the CS to go fully up against the frame.

But you can ride with it that way, if you don't adjust it, it only keeps the CS about 1" open. But I always remember it and just close the Brown last.
