As fate may have it, I may have a '75 R90/6 in my near future. My grandfather is moving into his 80's and starting to question his ability to ride. Earlier this year while moving the Beemer in the garage, his knee gave out and he dropped it. I think that combined with apprehension of some upcoming surgeries, was kind of the last straw for him. Last night he called and asked if I would have any interest in the Beemer. He says he isn't giving up riding, but doesn't see himself handling his bigger bikes anymore. I didn't really know what to say, I'd never even thought about it. I've decided to ride up to his place on Saturday and take it for a spin. I've ridden on this bike many times, but only as a kid on the back seat and many many years ago. Never been on it since I've started riding myself so I don't really know what to expect. Obviously, the ride will tell me a lot, but I'm still looking to find out as much as I can about what to expect on a bike like this. The last thing I want to do is accept his generous offer, only to end up not riding it much for one reason or another. I owe him, and the bike, better than that. What should I realistically expect from the R90 in terms of maintenance and reliability? Would it still make a reasonably reliable distance touring bike? Are parts available most places I might end up? I know from talking to my grandfather that general maintenance is dead simple due to the engine configuration, which is a major plus for an older bike especially. Obviously, it isn't going to be a quick bike by today's standards, but how does handling / braking compare when the bike is in good shape? I know the bike I'm looking at is in riding condition, but it may well need some work to be in top shape too, so I don't want to judge it's capabilities on the initial ride alone. Is it comfortable for long distances (say 400-500 miles) for a tall guy like myself? I'm 6'6 with a 38" inseam so I don't fit worth a crap on 90% of the bikes out there that were designed for normal sized people. Any things in particular I should be looking for / paying attention to? I've been kicking around the idea of adding a classic motorcycle for years, just for something different and to take things at a different pace. Bonus if it surprises people to see a young guy on it. The kicker is, it still needs to be fun though! I really enjoyed riding his Matchless thumper even though it was slow... but it was a small bike. Not sure I'll feel the same way about the BMW? I've never really been interested in a cruiser sort of bike, which I realize the BMW isn't really a cruiser, but compared to what I've been riding it is a few steps in that direction. Where I'm coming from (just as an aside): I've been riding for just shy of 10 years. Currently I'm riding a Buell 1125R with a ~15% bump from tuning and exhaust work. I've been looking pretty hard at a new bike recently as it is. I'm freakishly tall and can't ride the Buell for long distances with any degree of comfort. Also, I've had more than my fair share of mishaps due to throttle mismanagement over the last few years, so something a bit more sane in the power to weight department would be better for my health. My other bike is a '82 XS400 Seca that I learned on. I still keep it around, but it seldom gets ridden since it isn't any good on the highway and I rarely ride in town. From my research, I've all but settled on a KTM 990 SMT, even though I've never ridden one. Still sporty and fun, more distance capable, and a much more reasonable power output for me. I've ridden the BMW 1200GS, and Yamaha's Super Tenere, both are good bikes but from what I've read contrasting those (which I have ridden) with the KTM (which I haven't) the KTM would be a better fit. Seems it would make for a pretty good all rounder. The problem is actually finding one to test ride! Now, with the possibility of the BMW thrown in the mix, I am a bit less sure. The BMW may compliment the Buell's weaknesses to an extent, though I can see myself still getting the KTM eventually anyway and then the question becomes would I ride the BMW enough to avoid guilt in taking it? I'd like to think that I would, but I just don't know. Sorry for having a bit of a rant, I'm just mulling a lot of things over in my head right now.
