I want to try the sportsman class supermoto with my WR 250 but I'm not sure I want to lose my "dirt" bike in the process. Is it reasonable to just swap tires to try it out or do I need to change gearing, Brakes, rims etc just to make it worth it. And once it's done, do I need to get another dirtbike. These arent changes that would only take a few minutes. As far as I can tell it's a pretty serious committment. Sure looks like fun though. Anyone out there that has light to shed would be appreciated.
