As has been said, no reason to have one or the other. I have switched my DRZ back and forth for years. Plus I ride plenty of dirt and gravel on the SM wheels. Last few times out I have ridden ORV trails with wheel deep water crossings. Aside from the water crossings, the ORV trail has been easy enough that knobbies are not required. I also have a dedicated SM race bike and a dedicated dirt bike, so I just ride whatever I feel like riding. And no regrets!
i have the body work brand new and front forks clip ons from a new 07 gsxr750... shoot me an email.. [email protected]get a yzf, rmz, kxf, crf ect... then buy a set of wheels and brakes. takes me 30 minutes to go from full sumo to full dirt or vise versa. i have each set of wheels set up with their own rotors and sprockets. adjusting the chain for different gearing takes the most time for my swap. best of both worlds.
hoping to buy a super single set up then i can do everything with one bike. i have the marchesinis already, so i need the bodywork, clipons, rear sets, and suspension. then truely you have a do it all bike, supermoto, dirt, and road race. ski
