These vehicles shall be registered (allowed to be used on roads open to traffic).
Top speed is limited to 130km/h
Quads are set in two Groups :
- Group G/ Quad Racers: propelled by the action of two wheels (2 wheel driven).
Engine must be produced in a series and available on the market. Cylinder, cylinder head may be modified, with the exception of the crankcase, but must fulfil the FIM Technical Rules for Cross-Country Rallies Quads category.
The chassis is free (in design), material: steel
- Group H/ Quad Racers: propelled by the action of four wheels (4 wheel driven).
The engine minimum production quantities for engines shall be: 200 units* *The minimum required production quantities refer to units with identical equipment.
Evidence of engine production quantities may be required by FIM, certified by the manufacturer’s auditing firm and/or any other institution which may provide reliable documentation written in English.
The engine must be produced from a recognised and FIM licenced manufacturer. The engine number (stamped on the crankcase) must remain visible at all times. The following engine specifications and components may be altered from the original model:
- Cylinder head: Intake and exhaust tracts surfaces may be polished. No addition of material is allowed. The gasket is free and compression ratio can be modified.
- Camshafts and camshaft sprockets are free. Valve springs can be replaced but titanium springs are forbidden.
- Pistons, pistons rings, pins and clips: may be altered or replaced from those fitted to the engine.
- Exhaust system: Exhaust pipes and silencers may be altered or replaced.
- Clutch: An aftermarket or modified clutch is permitted.
- Radiator and/or oil cooler may be altered or replaced, additional radiators and oil cooler may be added.
- Oil pumps and oil liners may be altered or replaced. Oil lines containing positive pressure, if replaced, must be of metal reinforced construction with swaged or treaded connectors.
- Oil tanks may be added or modified.
- Air filter may be altered or replaced.
- Fuel pump may be modified or replaced.
- Ignition / Engine Control System (ECU), hardware and software may be modified or changed.
- Generator, alternator, electric starter may be modified or replaced.
- Secondary transmission is free.
During the event, an ‘engine change’ means removing the engine from the frame. Engine ‘A’ originally fitted in the frame of the bike can be removed from the frame to be repaired and be replaced by engine ‘B’ Engine ‘A’ may be repaired during the event on the condition that the engine crankcase(s) marked during the preliminary technical inspection remain(s) the same.
Repairs to the engine’s ‘top end’ (cylinder + cylinder head) are free during the event. All intervention to the ‘bottom-end’ (inside the crankcases) will be considered as a change of engine.
A minimum of one bolt/nut used to fix the engine must be drilled in order to attach a seal embracing the frame.
The engine may be removed from the frame to repair a problem not related to the crankcase. This intervention may be done only after formal request and under the supervision of the Technical Steward. Only the Technical Steward can cut and replace the seals without the participant being penalised.
The machine can operate on the front wheels only.
Chassis and ancillaries
Shock absorbers and associated springs are free.
Wheelbase, front and rear track are free but the overall width is defined by FIM Cross Country Rallyies Technical Rules.
The main chassis must be marked with the original Vehicle Identification Number (VIN). The frame number (VIN) must remain visible at all times.
The chassis shall not be replaced during the event. The frame may be repaired under the supervision of the Technical Steward.
For Group H only:
The main chassis may only be altered by addition of material, no material can be removed (except original engine fixing points if an alternative unit is installed).
The position on the chassis of steering pipe, swing arm, suspension linkage mounting points must remain as in the production Quad.
The rear sub-frame can be modified, but the type of material must remain as in the production model and the weight cannot be lower.
Fairing and body can be modified or replaced.
Seat may be modified or replaced.
Battery may be changed but the nominal energy must be equal or higher than the original one.
Footrests and foot controls may be modified or replaced.
Four number plates are required:
• 1 plate fixed to the front of the machine at the level of the head lamp, facing forward.
• 1 double-side rear plate made of flexible material set on the safety bar placed behind the saddle of the quad.
All the mountings of the front and rear suspension units, suspension arms and the steering spindle are retained by a safety wire or a splitpen.
For Group H only:
Steering linkages and suspension arms may be modified or replaced. The FIM may require demonstrating that the new parts present equivalent or higher mechanical properties to the original ones.
Brakes, wheels and rims
Disc brakes, callipers and associated pipes can be changed.
The rear wheel rim diameter cannot exceed 12 inches in Group G and 15 inches in Group H. Wire spokes are not authorised.
Every front wheel must have a single, functional brake installed on each axle and be operated by a handlebar mounted lever.
At the rear, the vehicle must have a brake on each wheel or a brake installed jointly on the rear wheel axle, operated either by a lever on the handlebar or by a foot pedal.
Wheels may be replaced but not modified. Magnesium alloys and carbon-reinforced wheels are forbidden.
The front and rear wheels must be covered by mudguards made of flexible materials, covering each wheel over an area of minimum 30 degrees.
Supplementary fuel tanks are allowed but must be at least 25 mm (1 inch) away with relation to the edges of the protective barrier.
The maximum fuel tank capacity (counting all tanks) is 45 litres.
Original fuel tanks can be modified or replaced but the fixing points on the chassis and the fixing system must be as in the original model. Supplementary fuel tanks are allowed.
The secondary chain transmission must be equipped with a cover/shield protecting both the chain sprocket and the brake disc.
A compulsory countershaft sprocket guard must cover the sprocket by 30% minimum and prevent the rider’s hand/foot becoming trapped.
The complete length of the lower chain run must be shielded by a guard or a protection tube, securely fixed.
A crash ‘bar’ or ‘guard’ must be fixed at the front and the rear of the vehicle.
A protective barrier (or ‘guard’) of a round profile (minimum diameter: 25 mm or 1 inch) must be installed on each side of the vehicle. This protective barrier must be fitted in such a way that it is in alignment with the wheels to eliminate entanglement. There shall be no prominent (sharp) parts.
A structure of crossed belts or a metallic grid must be fitted to fill the opening between the wheels and the barrier, to prevent the riders’ foot from accidentally touching the ground.
