hi guys, looking for a bigger LAMS bike to learn on and heard that 400+ offroad bikes might suit my height best (Im 180cm 83kg). I'm not planning taking it off-road. My budget is super entry level - $3-4K. So looking at 2003-2005 models or so. I've heard that some off-road bikes have to be maintained a lot more, as they are for racing off-road. I'd like to stay away from those, but don't know which ones are what.. These are what I heard have been recommended for taller riders: DRZ400, DR650, KLR650, XR400, WR450. Do any of these require more maintenance than normal? What about CRF450X? Looks that that one may be more competition focused? Would you recommend any other ones? Any KTMs? thanks!
