KX & RM100's are the same bike, just different coloured plastics. Year before last Kawasaki & Suzuki came to an agreement to help each other with R&D & try to get some of the market back. The little bikes are all the same and should be the same price, but I've noticed over here they differ about $300, so whichever is cheaper or which dealer is best, comes into effect.
The 80's will be different, as both companies had their own 80's before the agreement, as will 125's, 250's. The KLX/DRZ400 are the same also.
BlueRider, it still is a guy's sport, very much so, just more & more of us women are starting to ride. Oh, and if you did put "our" in there, it could be taken as our without gender (as in all of us dirtbike riders lol). ;)
