I'm an old desert biker needing to switch to something with 4 wheels and a cage. Currently, looking at buying one of the new RSR 1000's. My question has to do with the wheelbase difference between the 2 seater and the 4 seater. I know the longer the wheelbase the smoother the ride but is there that much difference between them. I will rarely take 4 riders cause it's just me and the old lady so I'm only concerned with the best ride between wheelbase lengths.
