I went up today and it was fun!
I got there just before 9 and made it into the first session which went out at 10:30. The route goes from Nukes up about 13 miles to where the road is closed and then back down. I'm a shorty with about a 30inch inseam so the bike is way taller than I really want to deal with on the streets but this is a simple route. You only have to touch the ground at the beginning, middle and end. They did say that a few had gel seats which are a little lower but mine didn't. For a demo ride, the pace was awesome, they went faster than I expected.
The bike was a ton of fun but in the end I'd either want a Monster or a real motard. The hyper is too heavy and big to be a motard. I want one that I can screw around and be crazy on, get pissed and kick it over and then pick it up and ride away.
