My jet boat has a wheel ...not sure if it qualifies as flat.since you mentioned dirtbikes..........did you know the PRO RMK is the only motorized recreational vehicle on the face of the earth with a flat steering setup?? Seadoos, snowmobiles, dirtbikes, quads all have the same steering. Polaris chooses to keep the flat steering because Burandt says its the best and they would have to engineer a new chassis to fit a proper steering post LOL. No wonder most RMK riders look like a newborn giraffe testing out its new legs
