F 900 GS Adventure 2026 vs R 1150 GS 2003

If straight-line speed is your priority, the F 900 GS Adventure takes the lead. With 20 HP more than the R 1150 GS, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 3kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Riders with a shorter inseam should lean towards the R 1150 GS. Its seat height is 35mm lower than the F 900 GS Adventure, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the f900gs offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
