Looking forward to reading about your project. I currently own a 05 300 EXC. Just starting to get back into dirt riding again after too long of a break. I want to do some mods to the 300 to make it a little more maneagable for my ridiing skills. Been very interested in the 530. I would love to have it as a second tool for the short rides of pavement to the riding areas. My 300 is the first KTM I have owned. I must say that it is by far the best dirt bike I have ridden so far. I just need to bring my skills back up to par, to make full use of the machine. Then I might sell a couple of bikes in the garage and get a 530.
Oh, you should consider coming out to NM, sometime for a rider clinic. I am sure you have ridden down here. Very nice place to ride dirt bikes.
