Long time lurker, first time poster. I used to ride an XR250 back in the early '90s, and this site has been great for helping me decide to get back on a bike. I'm about to pull the trigger on an 07 525exc and wanted some opinions on it. The bike has nearly 300 hours on it but has had the following items replaced recently: Piston / Valves / Seats (done by reputable KTM dealer), plastics, clutch, sprockets, chain and battery. Some upgrades include Clark 3.1 gallon tank, FMF exhaust, and soft seat. I am a little leary of buying this bike because of it's higher hours, but it seems like the RFS engines are pretty bulletproof with the right maintanence (seller claims oil changes every 4-6 hours). I believe I can get this bike for $3500-3600, which seems to be about what I can get an 04-05 with ~100 hours. The '07 is very appealing here in Oregon because we can't plate the older bikes for DS use. What should I look out for on this bike? Thanks!
