Motorbike Classes and Types
Motorbike classes as described below are determined by a combination of the rider's age, the bike's engine size and type (2 or 4 stroke), and then wheel size.
For example; A rider aged 13 riding a 125cc four stroke (4T) for example can be classed as a “Miniwheel” if it has small wheels, or a “85cc Small Wheel” if it has big wheels.
To determine what class your rider will be suitable for, you should:

To determine what class your rider will be suitable for, you should:
- First consider their age group. Then,
- Consider the engine capacity and type. Then
- Look at the bike's wheel size.

Low Budget Bikes
There are many different brands of dirtbike in the market today and not all are acceptable for motorcycle sport. Motorcycling Australia have published some rules pertaining to low budget dirtbikes that limit which makes and models can be used for Minikhana.
Electric Bikes
Whilst Motorcycling Australia allow electric bikes within the Minikhana discipline subject to certain criteria, we do not currently permit electric bikes at Hornsby Junior Dirt Bike Club.
Grading
Within each class there are three grades (excluding nipper and senior classes). Riders will compete for grading points that go towards a tally that promotes you to the higher grade. In order to accumulate grading points at a Regional Event, your riders class must start with four or more riders in it. If the class does not have a sufficient amount of riders available to start, you may be requested to ride up a grade for that competition. All points earned in this instant will go towards your grading points for your official grade, however, because you are competing against competitors of a higher grade, you will receive 17 points for 2nd place and 12 points for 3rd place as opposed to the normal grading points outlined below.
Points are awarded for podium positions only. Points are awarded on the podium as follows:
1st Place: 17 points
2nd Place: 12 points
3rd Place: 9 points
A rider placing 1st or 2nd in C Grade, will automatically be upgraded to B Grade. A rider placing 1st overall in B Grade will be automatically upgraded to A Grade. Once a rider accumulates 21 grading points in any combination, they will be eligible to move up to the next applicable grade.
When a rider moves from Miniwheels to 65cc, they will only drop one grade e.g. from Miniwheel A Grade to 65cc B Grade. If a rider moves two classes e.g. from Miniwheels to 85cc, they will drop two grades or start in C Grade. This is the same when upgrading from 50cc auto to Miniwheels, due to complexity of the new bike i.e. clutch and gears. When moving between 85cc Small Wheel and Big Wheels, you can still ride in the same class as you previously were.
