    We don'nt need no stinkin watercooled engines. Just design a damn useful seat that we do not have to spend another $500 dollars to replace!

    I have more power than I need now. Design some comfort and a lower frame for a change. And while your at it how about those six fuel strips I have replaced. Couldn't you have done a better job on that. Thier engineers are all Dutch-tall and long legs yea?

    there I said it and I feel better!

    We get to have the watercooled engines because of government regulations and testing. They can't test our *** the comfort so they cana't regulate the seat.

    Paul,
    how much trouble did you ever have with your K's final drives, out of curiosity? and what HP do they deliver?

    (not to hijack the thread at all)

    None - and K bikes range from 75 to 90 to 100 hp/

    And the same bearing is used in the monolever Airheads, classic K bikes, and Oilheads. Horsepower, weight, and bumps matter.

    Just wondering does anyone know what affect, if any, the mandatory lube change has had on the final drive failure rate?

    Since nobody but BMW knows the real failure rate overall, I sincerely doubt anybody knows how many failures were prevented by getting debris out of the final drives with the first oil change.

    with modern lubricants lasting longer, it still does seem to make sense to do the first change far ahead of recommended mileages, in order to clear debris. too bad there's no available data for the consumer on this one, from BMW. i wonder if anyone has any sense of whether or not other brands of motorcycle have had problems with their own shaft/final drives?

    hmmm. well that seems to lead us back to the discussion about HP *needs*- tho HP seems also (in this instance) to be a by-product of the new motor, with the intended end result being reduced emissions... i guess the bikes have gotten generally a bit heavier, too as of late. will overall bike weight increase with the advent of the new liquid cooled motor?

    also:
    think folks nowadays are riding farther & faster than ever before?
    was the final drive on the Oilheads as bullet proof as on the Airheads & Ks?

    Actually, the R1200s got significantly LIGHTER than the 1100s and 1150s. And the final drive problems seemed to begin with the 1150s, which had essentially the same design as the 1100s.

    yes but how much heavier were those models compared to vintage Ks and airheads?
    pardon my lack of knowing but are the 1100S and 1150S in the Oilhead family?

    Unladen weight fully fueled:
    R100R (airhead): 480 lb
    K100: 528 lb
    R1100R: 517 lb
    R1150R: 524 lb
    R1200R: 491 lb

    The R1200R got very close to the weight of an airhead. K bikes were the heavy weights.

    The R1100S is an oilhead. BMW did not make a R1150S to my knowledge.

    BMW did not make an 1150S, the 1100S was superceded by the R1200S, which is a horse of a vastly different color than the 1100S.

    FYI, wet weight of an R1100S is 230kg, 506 pounds.

    i love my RT. i saw this bike and had to have it. i just sold an older 930 P-car so it was doable. it feels "same thing only different" compared to the RT. like, apples and oranges different. i really like it. 491 pounds? i did not know that. j
