There are several types of DRZ400: * Enduro model (E) - This comes with off road wheels/tyres, slightly different rear swing arm, different suspension, plastic fuel tank, different sprocket ratios etc. * Adventure (S) - This is setup for a mix of on/off road riding. Comes with different tyres, probably different sprocket ratios to make it more pleasant for riding on road. * Super Motard (SM) - The bike was reworked to be pure on road. Has a shorter/different swing arm, different suspension, different sprocket ratios etc.

Yeah, something like that, but with street rims/tyres on it.
