That looks like a nice track for the B4. What track is that and is the whole track as twisty as this part in the photos?

The track is Virginia Int'l Raceway, North Course, same as the AMA races in September. It is a blast with a lot of up and down hills with a good mix of fast and tight turns. They have 2 other track configurations there as well, Patriot is much tighter and "Full Course" is much longer. I have only ridden North as of now, but I think Patriot would be a blast on the B4, I might do it later this year.
