I ride with my wife on pillion regularly and neither of us are lightweight!, riding where this machine is at home on the uk A & B roads up to 60-65MPH (occasionally 70) with more smiles per mile than some other bikes Ive owned, I made a front seat to fit where the rear pillion pad was using the bikes original mounting points so its reversable, which has made it much more comfotable for my wife.
I can't recall ever bottoming out on the suspension either, and some of the so called B roads we've been on were little more than cart tracks
