For metallic protection, the maximum distance between the lower edge of the upper tube and the upper edge of the lower tube
shall not exceed 100 mm.
In addition, regardless of the direction of contact between two karts, opening faces of the protection shall
correspond over a minimum vertical contact of 80 mm the kart being on a level surface with no steering input.
For tubular system, the upper and lower tubes shall correspond respectively.
All types of karts shall be provided with frontal, side and rear absorption energy systems.
The energy absorption systems shall be able to maintain their absorption properties under repeated low speed
impacts. Additional tubes to protect air box as part of all around protection are permitted.
Karts shall be fitted with energy absorbing devices complying with the specifications described in Annex B
(crash test protocols – frontal, side and rear crash).
If different models of karts are to be used on the same track at the same time then it will be necessary to
ensure that both kart protection systems are compatible.
In order to prove that absorption property are adequate and maintained after recurring impacts, crash test
according to Annex B should be repeated four times for each direction of impact. The resultant acceleration
measured on the kart should not exceed the following upper limits for all the impact events.
For Kart type A2, B, C1:
Frontal crash maximum acceleration allowed: 15 g
Left and right side crash maximum acceleration allowed: 15 g
Rear crash maximum acceleration allowed: 20 g
For Kart type C2:
Frontal crash maximum acceleration allowed: 15 g
Left and right side crash maximum acceleration allowed: 20 g
Rear crash maximum acceleration allowed: 20 g

C1 and C2 shall reach a residual performance (Pr) of at least 60 %.
When a kart manufacturer is fitting the same brake system (at least the control, the transmission cable(s), the
actuator(s) and the brake linings shall not differ) to different kart types and models of an identified family, it
does not need to repeat the dynamic tests provided that the following conditions have been met:
the dynamic tests have been performed on the heaviest kart type/model;
the dynamic tests have been performed on the fastest kart type/model.

6.4 Protection against failure of control systems
6.4.1 Brake system controls
6.4.1.1 General
Karts shall have, at least, one brake system acting on both wheels of the rear axle. Where the rear axle is
split, or a differential is fitted, the brake system shall apply one brake for each rear wheel.
The elements of the brake system shall be protected against self loosening.
All necessary instructions for a proper maintenance of the brake system and of the relevant controls shall be
given in the user maintenance guide described in clause 8.2.
6.4.1.2 Mechanical components of the brake system
The brake pedal shall be connected in two points to the chassis or to the brake mechanism.
The transmission elements, i.e. brake cable and brake linkage, shall be connected twice.
Control cables of shall be fitted to the vehicle so as to prevent unintentional activation and damage.
Additionally they shall be installed in the area of the base plate so that a cable extension or a hanging out of
the pulls by foot or by hand, as well as mechanical damage during getting into and off the vehicle, is
prevented (e.g. guide pipe or fixing of the external covering).
Thread ends of brake linkages shall be rolled.
6.4.1.3 Hydraulic components of the brake system
Hydraulic brake systems shall have hoses with an external sheath (e.g braid) protecting them from external
abuse.
Hydraulic lines shall be fitted to the vehicle so as to prevent unintentional activation and damage.
6.4.2 Steering wheel
The distance between the handgrips shall be:
275 mm minimum, 350 mm maximum for adults,
275 mm minimum, 325 mm maximum for children.
The handgrips shall be suitably shaped to allow a firm grasp and have a 150 mm minimum length on each
side.
The steering wheel shall be designed so that it shows no brittle failure in a crash situation, leading to sharp
edges and (or) injury from the steering column.
The centre of the steering wheel shall be closed so as to prevent the steering column penetrating the wheel.
Self locking fixings shall be used.
Steering wheel fixings facing the driver and exceeding 20
