The Husky looks sick. I just built my 426 and did two track days. The thing is a blast. You can brake way deep and pick any line you want pretty much. I don't understand why more people don't ride them. If we could only get the OEM to build more of them. The DRZ is okay and would consider one for the street.
The only problems I had on mine were poor selection of tires, chain rub on tire and rim, tried to push chain slider too long before changing, and gearing way too short for the track. I guess this is part of learning curve for these things.
