Here's my perspective, KTM and Huskies are GREAT bikes, make a lot of power too BUT; they are Very Expensive (New) and they don't have as great of a Dealer Network. Me I'd love a 'berg but Price and Dealer support is a drawback.
Performance wise the Euros will smoke the Jap bikes, but the only Real Street Tards Are the KTM 625SMC and the Husky SM610. The KTM vibrates like a mofo which I find very annoying. Haven't ridden the husky or a 'berg but I hear they're awesome. There's a 450SMR and 510 by husky that are "Street legal" but require more upkeep as they're really race bikes.
I bought the Honda XRL and it might not be as razor sharp as the DRZ, but it's a good bike, smooth motor(for a thumper), motor is bulletproof, has plenty of torque, and I can take it on pretty long rides, maintenance intervals are just like any other street bike and parts availability isn't a problem. I bought mine with the 'motard wheels already on the bike which probably saved me ~$1,000 over converting it myself. I still dumped a bit of $$$$ into the bike getting it where I wanted it though. If it's going to be your only bike IMO it's the perfect compromise.
