Engine Measuring
Riders maybe randomly selected for engine measuring at each round.
The selected competitors will be notified and will need to have their machines available
for inspection after the first day of competition. 

Engines measured will need to be within a 2% cc tolerance of the class limit,
competitors whose machines are found to be outside of these tolerances
will be disqualified from the championship and all points scored up to that point
will be forfeit.
Competitors who have failed a measurement will need to produce their machine for
re-examination prior to being permitted to compete in the championship further.

The Permitted class capacities are as follows:

Electric class - 8KW maximum
50cc class - 50cc maximum

88cc class - 88cc maximum
110cc class - 112cc maximum
125cc class - 125cc maximum
140cc class - 140cc maximum
160cc class - 160cc maximum
All machines in their standard format must comply with the class requirements prior to
any tolerance allowance.

Failure to present your machine for measuring without sufficient reason, as decided
by the MCF, will result in the same penalty for the competitor as a failed test.
