Any one know if a 1983 R65LS center stand will fit my 1981 R65? I have a "standard" 1983 R65 but no LS for comparison.
I've checked A&S and the parts numbers are the same although the actual parts are different in the foot pad design. The 1981 BMW center stands were a one-year design. If you've ever attempted to grunt an '81 onto the stand, you'll know.
May have a line. Looking for a possible confirmation. BTW, is their any difference in R65 and R65LS main frame design?
TIA, Monte
-
I'd sure like to know as well, the LS I have is about 10% of the work to get it on the centerstand, compared to the '81 R65 .

Well, d'oh! Just did a quickie measurement of leg lengths on my '81 and '83 R65 center stands.
The '81 is longer by approx 0.75 inch. The '83 is a breeze to place on the center stand whereas the '81 requires a pretty heavy grunt. I believe the longer stand legs means it's necessary to lift the bike higher before it will flop back down onto the extended stand.
The '81 has a flat strap "shackle" from a frame pivot to a short spring and then onto the hook on the center stand cross member. The '83 gets rid of a potential connection rattle by using a longer straight wire length and then the same coil-length spring.
Chassis are the same. I'm betting the LS chassis and center stand is the same as on my '83.

So... I've put in a bid for a 1983 R65LS center stand offered on eBay by one of our members, Larry Chabira, aka: lamontsanford, out of Austin, Texas. Question: Am I bidding against anybody on this list? It's not an absolute must have item so I don't wish to drive up the price too far for either of us. ;)

Monte, FWIW, my son Earl Phorqs has a Reynolds stand on his 83 R65 and it's totally effortless to get on and off the stand. If you don't get this one then keep that in mind.

Is this what's know as a "ride off" stand? Monte

+1 on that, Monte! and FWIW, I found that getting my '81 off the OEM stand was even more of a grunt. Buying the later-model stand was about the best use I've made for the $$ I've spent on my bike.

I've nearly always seen the Reynolds listed in print as a "Reynolds Ride-Off" stand.

Yep, the correct term would be Reynolds Ride-Off Stand, but since you were in the military for so long, I should have styled it "Stand, motorcycle, ride-off, Reynolds, mil.spec.xxxxxxxxxxx.
-
I put a Reynolds Ride-Off stand on my 1st R65, and that was one of the very 1st mods I did to SC John's Britta too.
Frankly, I love the things, and will put them on any future Airheads I may ever acquire, as long as they can still be found.

My center stand is really a pain to use and sometimes I think it was not meant to use on my R65... why?
Because when I bought the R65 the PO only had installed the side-stand, but he told me a friend of him was going to get him a center-stand and after two weeks he did gets him and he posted it to me.
Why I think it could not be the right model: it is really heavy to put the bike on it. When I pull it up, it scratches a little bit the muffler ring (that connects the muffler to the tubes that come from the engine, sorry can't remember the name in english).
Are there any ways to check if we have got the right model? Does a R60/R90, etc center-stand work on a R65?
Regards...

What size front wheel does the 81 have?
If it's a 19" that might explain why the LS stand is shorter?
I understood that the LS frame is the same as the standard model but I guess there could be variations in the model years.
-
Sergio,
You could possibly check BMW part numbers to see if the R65's is the same number as the centerstand from the R60/R90. I kinda doubt it would fit.
Can you post a close-up photo of the stand on your R65? We might be able to confirm if it is indeed an R65 centerstand.

My '81 has 18" snowflake wheels, front & rear. I haven't heard of any OEM R65's having a different size, or two dissimilar sizes on one bike.

I think your best bet would be to find one that was OEM for a SWB R80 or R75 (SWB, also), and I would be very careful about those, even. The R65 supposedly was a pilot for larger SWB bikes, but who knows?

Close, except for two things:
1. It's more accurate to say that "I haven't been in the military in so long." (See #2 below.)
2. Mil.spec? I don't recall that term existing, back when. Then, catalogs and TMs identified items by FSN (Federal Stock Number).
At the risk of instigating an OT rant, I'll state that I've had the impression that the principal beneficiary of the "milspec" has been not the military, but rather the contractors. I'm of the subjective opinion that there are very few items that last long enough, are reliable enough, and their non-milspec counterparts to justify their higher cost to the government.
I have some examples of procurement stupidity — small quantities of nonstandard items that must be custom-manufactured because of their nonconforming specs, thus driving the unit cost through the roof — or concepts that were so ill-conceived that even the contractor tried to dissuade the military from buying them. Because I don't want to give the Forum Czar heartburn, I'll save them for later.

Oooh, JT, you must be REALLY old. FSN had been superceeded by NSN (National Stock Number)by the time I enlisted and I'm sorta old! [smiley=ROTFLMAO.gif] I believe it was just the FSN with two additional digits prepended (?) to it.
-
Everything I deal with on a regular basis, is Mil-Spec, with manufacturer spec codes after the Mil-Spec number .

Do you see what you've started, Mike? [smiley=ROTFLMAO.gif]
BTW, I scored the '83 R65 center stand offered by Larry "Lamont" Chabira on eBay. After measuring my '81 and '83 R65s chassis, I'm sure it will fit just fine. Goodbye, back strain!
We now return you to our regularly scheduled programming.

Must be all '81s. I swapped the Reynolds off my '81 R100 for a few days because I don't like the fact that on the road you'd need to find something to put under the stand if you needed to get a wheel off the ground. I couldn't get the stocker back off fast enough! And on the opposite end of the spectrum was the '95, it was pretty much effortless...
-
The 1981 BMW center stand was/is most certainly an anomaly on the R65. Everyone hates 'em... except maybe Arnold, the Califonicator Governor.
My '83 R65 is an easy-up onto the stand. Fix the '81 and I'll be happy to give my back a rest.

On my 1979 R65 it's well easy to pull the thing on the stand. Getting it off is the problem! The stand goes way over-center, leaving both wheels firmly on the floor. This does not seem right but the stand does not look worn or bent. Mystery.

Given the pivot bushes are OK The problem is usually wear at the top edges of the stand where they butt up against the frame stops. They will need building up with weld and grinding down again to fit. My stand is getting the same way. I keep putting it off while I'm using the bike every day.

Mine works OK. But I am a burly, muscular dude.
There, now NOBODY will recognize me at Redmond! ;D

My 80 r-65 came with a ride off stand putting it up on the stand is almost effortless and driving off is very nice the only problem encountered so far was using it on a gravel drive while I opened the manual gate at work and turning back to find the bike on it's head with the engine still running until it fludded out that (SUCKS) but the only damage was to the windshield a few scratches and a crack away from the upper mount hole I'm now looking for a new windseild.

Thanks Barry I'm sure you're right. That's beyond my capacities as a mechanic so it's a job to add to a couple of others to be done soon by someone clever - I will try Cray Engineering in Faversham, about 20 miles away.

Mister FedEx dropped off the new-to-me 1983 R65 center stand on Thursday. Cleaned it, worked it over with a metal prep disc, primed and painted. Installed on Monday.
The 1981 R65 center stand design is a groin buster if there ever was one. It was a one-year-design only so us '81 owners can't be a girlie man.
Couple or so discoveries...
The 81 utilizes a pair of stamped metal "toggles" with big hooks for the springs welded on one end. These toggles pivot on short, frame-attached studs. The retract springs then attach to the toggle hooks and on down to the center stand. Lottsa hooks.
The 83 uses springs with longer straight ends that eliminate the earlier design toggles. The problem I discovered is that the engine crankcase secures the open end of the stud and also blocks removal of the toggles. The stud is used with the new stand but how the blankity-blank do you get the toggles off without removing the engine?
[smiley=furious3.gif]
Not enough room to Dremel cut 'em free but -cue the lightbulb- a pair of small, needlenose vise grips worked to bend the toggle back and forth until it work hardened and failed right at the stud attach opening. Whew.
The side stand pivot bushings for the 83 are shorter than those fitted to the 81. Fortunately, the new stand came with all the hardware and springs. Thank you, lamontsanford in Austin!
The second lightbulb lit when I found it to be far easier to attach the retract springs if I hooked 'em onto the center stand and frame studs before installing the stand's pivot bolts.
I've rolled the bike onto the new stand about a dozen times already just because it's now so easy. [smiley=clap.gif]

The holes in the spring mounts are key-hole shaped and the ones on our 1980 will come off if you push up and then off the pivot...

And so I noticed and Oh, how I tried. Lord knows I tried.
Unfortunately, the rolled edges of the toggle/shackle,POS, whatever, would not allow that good idea to happen. So it was kinda like NCSteve with his hammer, helping out SCJJ.
