| Competition Bike
Concept: To introduce a class for stock Harley Davidson V Rod Destroyers.
The proposed rules are similar to those used in the USA for these bikes.
Reason: There is a relatively large number of these bikes and the majority of owners
have bought them as a “turn key race bike” and would like to keep them as
they came from the factory, rather than modifying them.
There is also enough of these bikes that they deserve to have their own set of
rules and index to race in the Comp Bike bracket.
