Closed Range Concept
The closed range concept for superadvanced motorcycle rider training was pioneered by Lee Parks when he put the methods outlined in his book Total Control to use in the Total Control Superadvanced Riding Clinics. Until then, only basic motorcycle training and simple machine control excercises were carried out on closed ranges as it was thought you couldn't possible do superadvanced exercises on a car park, you needed at least a race track for that sort of thing.
Ever the innovator, Lee showed that there was an awful lot of advanced riding you could do on a closed range even to the extent that a closed ranged proved far superior to a race track for a lot of essential exercises.
The exercises that we do on the closed range will certainly challenge your abilities, yet they do provide a valuable way of giving you specific and measurable improvements in your riding.
A great advantage of the closed range is that there is only ever one rider allowed on the range at any one time, which is less intimidating and much safer than riding on a race track could ever be.
The essential element of the closed ranged is the exercise circle, which is simply a 40' diameter circle marked out with small rubber cones. It doesn't matter if you run over one of these small cones, they just ping out of the way and you hardly know you have hit one.
The exercise circle gives us perhaps the most extreme example of a corner you are ever likely to encounter. Corners out on the road or on the race track are nowhere near as radical as our exercise circles, so if you can manage them, the real world is somewhat simpler in comparison.
