Short distance record attempts
There is NO distinction between Category I and Category II, 2-wheeled motorcycles for World Record for short distance attempts
Motorcycle (vehicle) classes fall into three Divisions.
Division A – Non-streamlined:
The rider is visible at all times. No streamlining devices are permitted.
Division B – Partially streamlined:
The rider is visible when viewed from both sides and from above (with the exception of hands and wrists). Front and rear wheel must remain partially uncovered (min 180°).
Division C – Streamlined:
The rider is fully enclosed within the body of the vehicle.
Divisions are sorted by Types and Classes (see Divisions chart)
CATEGORIES, GROUPS, DIVISIONS, TYPES AND CLASSES
‘Categories’ describe the method by which the motorcycle is propelled. ‘Categories’ are further defined by ‘Groups’. ‘Divisions’ define the degree of streamlining. ‘Types’ are determined by power source and then subdivided into ‘Classes’. ‘Classes’ are determined by total engine displacement.
Categories and Groups
Category I
Motorcycles propelled by the action of one wheel in contact with the ground.
Group A1 Solo Motorcycles
2-wheeler vehicles making only one track on the ground.
Solo Motorcycles – Mono cylinder (according to the class capacities, up to 1000cc maximum), Division A and B.
Solo Motorcycles – Two cylinders (according to the class capacities, up to 3000cc maximum), Division A and B
Group A2 Scooters
Motorcycles with special characteristics (see definition ‘Scooters’). A scooter must
have its crankcase/swing-arm constructed into one single, rigid unit.
Group A3 Automatic 50 cc
Motorcycles driven by an engine capacity up to 50 cc and having automatic transmission
Group B1 Motorcycles with permanent Sidecar
Vehicles with three wheels, making two tracks on the ground, consisting of a motorcycle making one track, and a Sidecar for a passenger making the other.
Group B2 Motorcycles with permanent Sidecar
Vehicles with three wheels, making two or three tracks on the ground in the direction of forward travel, with a permanently attached Sidecar forming a complete integral unit.
If three tracks are made, the centre-line of the two tracks made by the motorcycle wheels must not be more than 75 mm apart. A track is determined by the longitudinal centre-line of each of the vehicle’s wheels in the direction of forward
Group B3 Cycle-cars
3-wheeled vehicles making three tracks on the ground forming a complete integral unit and having accommodation for a rider and passenger.
A cycle-car is a motorcycle with 3 wheels differing from a Sidecar in that 2 of the wheels are mounted on the same geometric horizontal axis. These may be on the front or rear of the vehicle and shall ensure stability of the vehicle.
Steering must be by handlebars with a minimum length of 500 mm or by a wheel with a minimum diameter of 300 mm.
The passenger can be by the side of the rider but not necessarily in the same frontal alignment. He can also be placed behind the rider. If bodywork does not enclose the wheels, wheels must be protected by mudguards.
Category II
Motorcycles propelled by the action of two wheels in contact with the ground.
Group A1 Solo Motorcycles
2-wheeled vehicles making only one track on the ground.
Category III
Special vehicles propelled by the action of one or more wheels or track devices in contact with the ground but which are not covered by the conditions for Category I or II.
Group E Snowmobiles
Group G Quad Racers
Category IV
Special vehicles not propelled by wheels in contact with the ground.
Group Y Specials
