    R80RT or R100RT, and why?

    Ever once in a while, I find myself lusting after an RT model airhead. For example, when I see something like the Alps photo on page 57 of the June issue of the ON.

    My interests always seems to focus on either the R80, or the R100. I keep thinking, "One of these days, I'll run up on what I want and trade the K model."

    Since I've never owned an airhead, I thought I would appeal to the opinion of those on this forum to see what you have, or which you would choose, and why.

    Probably, I am the only motorcyclist in the world seized by such episodes of mental duress -- but then, I could as easily be wrong ...

    Look in the Ads for your answer!!

    If you do some checking in the ads you will find that the R80RT is harder to find, ever wonder why?

    I spent almost a year and a half trying to find my R80RT, they were few and far between. Most were in other parts of the country, so not practical to purchase. When I finally found my bike, I actually found two R80RT's within a couple of weeks. The first one was a very nice looking red bike (84'), but when I looked at it found some damage that the owner "claimed" he knew nothing about. Later found out he had been the one to damage the bike (dropped it and broke the right mirror and damaged the lower fairing on both sides). This person was asking too much for the bike with the damage it had and would not come down to a fair price. A week later found my bike, original owner with complete records and well maintained. Paid his price because it was fair!

    Why the R80RT over the R100RT?

    I have alway considered the R80RT to be the definitive early 80's airhead for BMW. It was the combination of sport bike and touring bike, the first real sport touring bike! Just the right size for one up touring. But, quite capable of handling those twisty roads most riders love. (if you really wanted to do two up then the R100RT was you bike) In talking to various mechanics and others I have heard that the R80RT is more trouble free than the R100RT as well.

    Hello Rick,

    R80RT or R100RT tough question. I've had my 86 R80RT since 1988. Truly an amazing travelling companion for one up touring up to 75 mph. If, however, you need to go two-up then I would strongly suggest the R100RT.

    Please do not get me wrong the R80RT will handle two-up duties quite well but as was said before the more power the better.

    Good luck.

    At any given road speed in the same gear the R80RT will turn 1000 rpm more than the R100RT and return poorer fuel economy and less performance doing so.

    Folks should realize that the R80RT and R100RT are the exact same bike except for sizes of cylinders and pistons, and since the R80's are smaller, its carburetors are smaller, too (earlier versions). There is no noticeable weight difference and absolutely no physical size difference.

    There's just no reason for the R80RT that I can fathom.

    Interesting Facts?

    In light of the previous statements, I did a little checking:

    1983 R80RT:
    Curb Weight = 516 lbs, Wheel base = 57.7 in., Power 50 @ 6500

    1983 R100RT:
    Curb Weight = 525 lb, Wheel Base = 56.7 Power 70 bhp @ 7250

    Runs a 1000 RPM Higher huh? Weight the same Huh?

    Hmm.

    The weight difference as cited above is 2%. Not exactly enough to tell it while sitting at a stoplight, or even when (heaven forbid) lifting it off the carport deck.

    However, the horsepower difference is nearly 30%. That is interesting -- even to someone as mechanically challenged as I.

    Since I am mentioning numbers, I might as well observe that 99% + of my riding is solo. What that means is that about once a year, my wife or one of my kids will ask to go for a ride. So when I one day make a trade, it will be with the solo thing in mind.

    The styling on the classic BMW's has always attracted me, and false humility aside, I don't mind doing the tune ups and other routine maintenance.

    Thanks for the feedback and food for thought.

    It's the classic style for me also ...

    I agree, it's the classic style for me as well. I think the big issue here of the R80RT vs. the R100RT is which you like better. I have loved the R80RT since it first was introduced in 1983. It was my dream bike for over twenty years. Being able to finally purchase one to ride was my highlight of last year. While the R80RT and the R100RT are very similar, and the R100 is a larger displacement more powerful version, I still prefer the R80. I think it really comes down to which is the right bike for you.

    If you look at the history of BMW I think you will find these two bikes are really a piviotal bike in the evolution of the BMW. The are basically the last, and high point in design, for the Classic BMW. After them BMW saw many changes, K-bikes, 4-valve airheads, even a chain drive single (I am restoring one of the original singles, an R26).

    As to the differences between the R80 and R100, I think the R80 was suppose to be the affordable BMW of its time. It was designed to compete with the Japanese and Brit 750 cc bike of that era. While the R100 was designed to compete with the super bikes that the Japanese and Brits were introducting. The beauty was they were better built, more reliable bike than any of its competition, but cost more initially. While the Japanese and Brit bikes were less expensive, their life expectancy was about half that of a BMW. Also, the maintenance cost on those Japanese and Brit bikes was higher over the long haul than the BMW's.

    What about the RS?

    It is truly an amazing fairing offering great wind protection. The RT does offer a much more upright riding position, but I put bar-backs on my RS and find this the best all-around riding position (for me). The RS really was the true airhead sport-touring bike.

    Between the two RT's you're talking about, it's a no-brainer in my book. I don't think anyone has ever asked for less power.

    I thought the R100RS was the first Sport-Touring bike. I always considered the RT as a full tourer, before the big Luxury Tourers arrived.

    RE: Drool

    MarkF, Yes that is a VERY pretty bike! As to the previous comment on the Sport Touring bikes, yes the R100RS is the true sport touring bike, but the RT models of that era were more closely related to Sport Touring than they were to the Full-up Goldwings and Luxury Touring bikes. Even today the R1150RT is more like a Sport Touring bike than the Luxury Touring bikes we see from the other manufacturers.

    The big difference between the RT and RS models was the fairing height and size of the windscreen. Otherwise they were very much the same bike. Let's be honest BMW has always built bikes for the riders that like curvy roads, rather than open freeways (except of course the Autoban in Germany).

    Lets be honest, BMW always has and still does (to a lesser extent) build one bike (R-bike) with the same motor, tranny, frame, etc. It just hangs on different bodywork for different functions. I miss the days when you could convert from one model to another with relative ease.

    Personally, my temperament is more that of an RS rider, but a damaged rotator cuff in my right shoulder keeps me from accepting an aggressive riding posture.

    Nice pictures.
