I'm new to the dual sport arena. I've ridden dirt bikes and quads my whole life. Just sold my Harley the other day and want to get back to the dirt but still ride on the road. I've been looking at ktms but can't decide what to get. I have 2 that really interest me 2005 525 exc r supermoto that is plated. Approx 4000 miles. Set up for racing, comes with a set of dirt tires and wheels. Among other mods. 2009 530 xc w that is plated. Approx 1100 miles. Plenty of upgrades done on this also. I weight about 250 and want to be able to ride it to work as well as go bomb trails and FS roads. Also, would a 450 be to small for what I'm looking to do? Are there any problems that I need to look for or ask th seller when I go look at them? Thanks for any help you guys can offer.
