When I think of a bike circuit, there are a couple that spring to mind...
Phillip Island and
Ricardo Tormo in Valencia.
Polar opposites in many ways, one has barely a straight worth the terminology full of sweepers into tighter corners that mean trailbraking everywhere. The other apart from the main straight, is a series of short punchy straights with fairly tight corners.
The only common type corner would be Valencia's curved approach into the final corner.
