    R1100s

    What are the differences with the S model from like the RS - besides the look? Are they just more light weight or do they have any performance increase on the motors as well, different gear box? Thank you!

    Any of the several "S" fans can chime in more, but the big difference is the frame, and the 6 speed transmission as used in the R1150 models. I think there are also significant differences in the mapping in the ECUs.

    A significant difference!

    The "S" is far more fun and attractive than the RS. Just my .2 cents worth.

    Lighter, plus hotter cams and a tick more compression ratio to get 98 vs. 90 hp. Different internal transmission ratios, smaller fuel tank, can be fitted with two full sized panniers that don't have the indent for the RS muffler and probably lots more I can't think of right now. I certainly love mine!

    I believe the S also has a "sportier" seating position.

    Where is BC1100S when we need him?

    Owners of an "S" are also recognised for their rugged good looks, attractive female companions and their ability to quash all comers in a contest of speed. To even consider owning an RS may preclude one from "S" ownership.

    I do believe that Bluehole was selling conversion kits a few years ago.

    Voni had an S and an RS at the same time. She sold the S and bought a second RS so then had two RSs. Then she sold the second RS but kept the first RS, AKA Big Red. The too-ripe pumpkin color of the supposedly red S doomed it to be sold to someone who didn't care it was ugly.

    I know that colour...but have no comment for fear of hurting a fellow S owner's feelings.

    The Boxer Cup version (code X393A?) also had a torque arm (at the rear suspension) that was 20 mm shorter, for quicker handling.

    A worthy, and relatively cheap/easy, upgrade I did to my S. Had to add 7mm pads to the centrestand feet in order to keep the back tire off the ground when using the stand.
