Gentle persons, I have an R26 with a Steib S250 badged BMW. I haven't seen many (any besides mine) of these and I find that parts are hard to find. It is clearly referenced in my BMW manual but still rarely seen or referenced elsewhere. Wondering about the thoughts of the cognoscenti! Jim

P.S. Attached picture of me looking surly on the R26 with sidecar. With this kind of power you would look surly too!

Steib S250

Not sure if I qualify on the cognoscenti level but I have and owned several Steib sidecars. I currently own an S500 and an S500L. I have owned S501's which are quite rare as well. My Steib experience spans forty years and I have never seen an S250 except in Steib literature. Your sidecar looks excellent as it should. Pulling a steel bodied sidecar with a twelve horsepower single 250cc never made much sense but it looks fabulous. To me it's artwork, ride it to a local spot where vintage bikes gather and show it to those who have never seen one. I once owned a very nice and original R27, It had all it could do to pull itself down a level road. Hills were one or two down shifts on a solo bike. Enjoy your beautiful rig. Michael

Steib S250

Hi Michael, thanks for your comment. This rig started with the purchase of an R26 that seemed really slow. I looked at the gear ratio stamped on the gear housing and discovered that it had sidecar gearing. That started the search for a car. I found the S250 in Florida with the bottom rusted out. Took a while but finally made repair panels and got it all together. My wife and I have seen 50 MPH going downhill with a car so close he could have been pushing us. Not really a modern traffic machine. I think that I need a village to ride around in not the wide open spaces of the west. I do have some other particularly slow motorcycles. Life at 35 MPH is not all that bad. Jim

What was the marking that

What was the marking that indicates it's solo gearing? The specs indicate that 26/5 would be the rear drive for a sidecar. Also, not sure if the R26 came with a transmission with side car gearing also. (After looking some more, it seems that the singles didn't come with different transmissions, however.) On the twin cylinder bikes, an "S" by the speedometer input means solo gearing, not side car as many would think.

S250 solo gearing

Hi Kurt,

The rear drive is marked 26/5. My manual indicates that this is for a sidecar and my butt indicated that as well since it was soooo slow. Leaving the garage I had to shift into second.

My manual shows only one set of ratios for the gear box and no letters on the speedo. Jim

I've noticed on my R25/2 that

I've noticed on my R25/2 that the gearing for 1st is way, way low. Specifically, I notice that there is virtually no overlap in RPM between 1st to 2nd. Usually, once you've accelerated in a gear to a reasonable speed (and sound), if you shift up to the next gear, the RPM will be reasonable for that gear...you can throttle away. Not the case for my 1st-2nd. When I shift into 2nd, the RPM in my opinion is too low to really pull that well. I have to slowly feed throttle to get the speed up enough for good acceleration. In situations where I'm coming to a stop sign, I will routinely just roll the sign a little bit so that I can stay in 2nd. 1st is just for getting started...probably for use with a sidecar. My R25/2 has the balls on the frame for a sidecar.

I've heard that a different 1st gear can be substituted. I'll probably consider that if/when the transmission has to be opened up.

Oh, and I also don't get very smooth shifts 1st to 2nd...it will grind the gears. So, I have to shift to neutral, let the clutch handle out, then shift to 2nd...not so bad then.

Kurt, That is exactly why I

Kurt, That is exactly why I sold my beautiful R27. I would have to run the engine to the rev limiter in first gear and then let the engine spool down so I could shift into second gear then slowly build rpm's to keep it moving forward . I talked to an old BMW /2 authority about why my gearbox always ground a little every shift. I said I thought it needed work, although the bike had low miles and otherwise perfect condition. He said that's just how they work. A couple years ago I replied on this forum to a guy who was deciding whether to buy an R69S that was for sale or an R27. I replied, that was an easy call and gave my reasons why I would never consider an R27 as my daily rider. He bought the R27. Several members replied that I just needed to understand how these old bikes worked and I should be more patient.
I loved looking at my R27 but riding the bike was just slower than death on crutches. Now back to the gearbox issue. I just finished my R67/2 project which looks excellent and rides wonderful. I was having a similar little grind between shifts. I talked to an expert BMW restorer about this and he gave me a tip that really helped. As best as I can describe it, he said to preload the lever before you pull in the clutch. This is harder to do than it sounds because it seems odd to put(slight) pressure on the shift lever before you shift. Well, I have been doing this and my bike shifts much better with no grinding. Enjoy your ride 35 mph or beyond, Michael

Jim,I am fortunate to have

Jim,

I am fortunate to have just acquired an S250....
I am missing some bits, but overall, it's in incredible condition.
I AM missing what looks to be a small "T" shaped (?) aluminum trim piece that ties the tub cockpit surround to the front (center) aluminum trim strip.
Or, the holes may be for something other?

Any help appreciated

LS250

Here is the LS250 Steib that I purchased a few years ago from the second owners.
The story went that it was purchased from Dot Robinson out of Michigan and that they were all friends back in the day.
The claim was that since Dot and her husband had a dealership, they got all the cool stuff.
(Crotch cooling vent flap on the side was an owner added option)

This got me curious. I own a S501 and did not know they are 'rare'? What makes them rare and how to they differ from S500 and S500L?

Thanks,
Brian

S501 Steib

Hi Brian, Indeed the S501 is rare. They were the very last sidecars produced by Steib. The most distinguishing feature compared to other Steibs is it has shock absorbers, not a spring.
S350 S500 & S500L were all around many years before the S501.

Jim,I recently became the

Jim,

I just received a fender, cobra handle (just placed, for picture...not mounted yet), rear reflector and lenses from a fellow BMW acquaintance....
The remainder of the parts are en route from Berlin as we speak...
I am looking for some information specific to the S250, if you can be of assistance, i would be grateful.
Does yours have the (optional) side hydraulic shock/damper?
I need to know the size/thread pitch of the lower mount (back side of the axle)...
There was a broken off bolt in mine and I needed to drill it out...and will need to tap if I cannot get the remainder out.
(See picture for location)

Again, any help appreciated

Quick update... All metalwork

Quick update...
All metalwork done, all attachment bits (struts, etc) painted, fender painted.
Final paint on the tub should be done this weekend.
Very happy with the results and I can't wait to attach he to my '62 /2.

I am looking for specific production dates (year range)for the S250, if anyone can help.
