I had one of the first SD's - preowned by KTM, I bought it with 9,000 miles on it and sold it when it had 22,000 miles on it. I really regretted selling it. The only thing to note is that it's not so good for pillions
I found the fuel injection fine, had 16t sprocket, akras and some carbon. Did three of the Keith Code track schools on it- I was certainly the limiting factor.
Brilliant bike certainly the best so far ..after a year without a KTM I just bought a 950 SMR, the roads here are c*ap so some I'm hoping more suspension travel will help
