I'm a bit late to this party, but for what it's worth... when I brought the G15 I got stung for import fees and duties. But I was expecting it, just hoping to get away with it! The shipping company made it very easy in terms of processing and getting the shipment delivered though.
The G15 was surprisingly easy to ride in the "normal" tracks, although it never felt fast as such - just a bit more rig to throw around, but not cumbersome. Surprisingly, in line with rowdyflat comments above, I actually felt it was faster in some of the tight bits as my weight was in the right spot to get the front wheel tracking. I've never cornered better. I struggle to think of anything that would come close to giving me the confidence to hit steep technical stuff that the G15 does. I'm on a smaller bike for my local tracks as those rides aren't about out and out speed, but as a race bike damn the new geometry rocks.
