I just bought a R100/7. It came with a set (2) of aux tanks. Both are in excellent condition. Are these tanks rare? are they desireable on todays market? I'm trying ti decied if i'm going to keep them on the bike or go back to OEM side panels. I don't need them for function but they are cool! - thanks - slip

Slip -

The tanks were a limited run as I recall, so there aren't that many around. I've heard they come up for sale on fleabay every so often. I suppose they might be coveted by people who cover long distances without stopping - Iron Butt, runs to Alaska/Canada. Me, I need the stop every so often to stretch the legs, shake the blood out of the keister, drink some fluids, drain some fluids...

The tanks are color matched to your bike, so they might be of limited value to bikes of other colors. They could be repainted of course.

How do they work? Since the fuel system on the bike is gravity fed, I notice that the right side tank comes somewhat close to being on the same level as the carb, at least the bottom part of the tank. What's it like to sit on the bike with feet on the ground? It looks like they stick out enough that they would hit the inside of your legs.

If it were me, I'd probably hang on to the tanks but put them on the shelf. Then, when I had the desire to make a trip to the nether reaches of the country, I might strap them back on.

the 80 year old previous owner of the bike said they worked very well - as far as color thats a non-issue, at least for me as i'm repainting the bike anyway - they don't interfer with my leg room - i found a link to a site that talks about these tanks - i find them very interesting -

[url]http://pweb.jps.net/~snowbum/luftmstrtanks.htm

i have other bikes for touring so if i keep these i would put them back on the bike, they would be for a conversation piece only

i just found them kind of cool & interesting - something you don't see everyday - the last place they need to be would be on someones shelf hidden from the world!

I'm glad you found Snowbum's site...he has quite a bit to offer, if you can read far enough!! I looked earlier but failed to find the link. Actually, you should use this website and not the "jps.net" URL for his information.

http://bmwmotorcycletech.info/luftmstrtanks.htm

He was getting shutdown due to excess bandwidth every month so he got his own domain. He doesn't really update the jps site anymore, so the latest information will be on the other site.
