It 'looks' like a LWB to me ... Does it have the 2" (Edit: From 3", thanks wirewrkr) spacer welded in at the flange on the swingarm? I thought one of the pics looked like it. does it have the same wheel base as your 74?

Yup, looks like a LWB to me, too.

Also, I think I read somewhere that the LWB /5's have a large battery holder, and the SWB a small one. Can anyone confirm that?

That would be a 2" (50mm) spacer, not 3.
And yes it is definitely a LWB.
It was probably added. Once upon a time it was popular to do this. In those days the kit to do it was a hot commodity at BobS BMW. We couldn't keep the used parts on the shelf, they sold so fast.

Not from the factory. They didn't change out the holder until the /6 came along in the late summer of 73.

While we're at it, what's the scoop on the toaster tank? I've always read that they only came on 72s, but I see them all the time on 71s and 73s. Of course, they're easy to swap around, but it seems to be so widely done, I'm dubious that BMW only supplied them for a year.

I've heard the model year is actually about six months after the production date. My LWB R75/5 was manufactured in December of '72, but it wasn't shipped to the states and sold until a while later. Thus, it's a '73 on the original title. The same is probably true of yours. It definitely appears to have the extra length welded onto the swingarm.

Anyway, I don't know why I'm worrying about it. This is clearly a troll thread.

I'll be damned...it is a LWB. Went home and there is, in fact, a 2 inch section welded into the swing arm and it looks about the same size sitting next to the r90.

Would you mind sending some pics and info on that seat, Merge87?

Hey Blaine, I got home and dug it out and realized it's actually a very early /6 seat. Even has the plate on the back saying it's from an R90 /6. I think that could come off though and if I remember right the LWB /5's still had very similar seats. (?) I'll link some pics here and if you're still interested send me a message. Note, bottom does have some rust and there's no hinges. I just set it on my bike for one photo so you could get an idea of the look. Either way, best of luck with the project!

If blaine isn't interested, I would like to be considered next in line.

Dang, start a list. Maybe you don't realize it but that is a fine looking seat. I'm third in line. Ah, but it's not worth all that much...

Well, you guys are starting to convince me to swap it out. Both my seats are in pretty good condition. I'm kinda new overall to airheads still, do a lot of people keep two seats? (I won two at the same time on ebay on accident so didn't didn't know what to do)

Sorry to hijack your thread Blaine, definitely don't wanna steal your thunder

Just an extra seat? And you're worried? I have gas tanks, pistons & cylinders (none the right size for this bike), extra bags, forks, brake parts, engine parts. I think I could almost build a complete bike if I had the frame. And I do this just as a hobby. Some of these other guys on this list are professional junk collectors.
