A style of sport motorcycle riding. 'hyper' is a sport rider term used for experienced twistie riders. As in those that have basic skills, that generally don't like racing or being chased or chasing track tails. Hyper is slow, within the comfort zone, based upon one's skill level, but well within the design parameters of using a sport bike to slam into a twist, and roll on the exit.
Dirt riders have to go through a period of sorting out tire trust.
Once they get this handled, then hyper riding on the street comes together with their motocross background.
