A few weeks ago I went for a ride with a big group of guys, and the leader had something very, very similar, though I think it may have been a KTM, and I've gotta say, on tight, twisty courses, they're FAST! They look like a lot of fun, too. The guy who owned it said they needed to almost relearn how to ride, I've gotta wonder what the learning curve is like.
Either way, have fun man, thats a fun bike you're looking at.
