When there is a commercial demand for a course of this nature , i will more than happily oblige -
I do remember a certain person getting "clutch /slow speed control " hammered into the by a certain instructor not that long ago
I do feel that although this is an important skill - there are many others that must bet taught and practiced to keep sharp eg. cornering , braking , observation and planning to name a few.
We offer this but don't see many people trying to knock our door down to attend them - maby no one requires them

or prefer the conventional way to learn to ride a bike - crash FIRST then if you survive then you must be OK at it !!
