    It's probably been asked before, but what's the difference..

    So, what is the difference between S, RS, RT, GS, etc? I know the differences in the /'s.. but what do these other designations mean?

    S, RS, and RT are TRIM variations on the same bike.

    Different fairings plus bars, etc. to match

    For R100s except for 1977 and 1978 the drivetrains are identical in a given year. In a given year there was only ever one R80 variant.

    GS is an entirely unique, smaller frame shared with R100R.

    G/S frame was similarly shared with ST.

    Pre '85 R65 were a third unique frame. Post '85 R65 frame is same as R80, R100.

    Big frame bikes were called /7 through 1980, and this includes S, RS, and RT.

    Bikes were substantially modified from /7 configuration in 1981 and again in 1985. Were the same 1985-1995.

    R80 and R100 engines are identical except for cylinder barrels and pistons. Same crank, same stroke. All bikes have same transmission but R80 bikes have different rear drive gearing than R100 bikes. In '77 and '78, R100/7 have different rear gearing than others, as they are lower powered, with lower compression and smaller carbs.

    Exactly what I wanted to know. Now, it's only going to take me a year to remember all this.

    Nah, it's easy:

    S = Sport
    RS = Touring
    ST = Sport Touring
    GS = Dual Sport

    ST = Sport Touring, in a limited quantity

    RT = Sport Touring, behind a Touring fairing
