20. FINISH OF A RACE.

When the leading driver on the track has completed the designated number of laps or duration for the race, a chequered flag will be displayed as that driver crosses the finish line. The chequered flag will continue to be displayed to the subsequent drivers, until the last driver completes that lap. The onus of completing the required number of laps rests with the driver, but no driver will be allowed to start a fresh lap after the chequered flag has been displayed.

In case of a photo-finish between two, or more, drivers, the decision shall be taken in favour of the driver whose front wheel leading edge crosses the plane of the finish line first. In case of ties, the drivers concerned will be ranked in the order of the best lap time made during the race.

Should for any reason the chequered flag be given before the leading driver completes the scheduled number of laps or duration, the race will be deemed to have finished. If the chequered flag is given to the leader then a result will be drawn accordingly, but if the chequered flag is given to a driver other than the leader then the result will be taken when the leader last crossed the finish line before the signal was given. Should the end of race signal be delayed for any reason, the race will be deemed to have finished when it should have finished and the drivers classified accordingly.

The results will be based on the most number of laps completed in the least time, corrected for group start time differences. To be counted as a finisher in the race and be included in the results a driver must have: i.) completed 75% of the number of laps carried out by the winner. ii.) crossed the finish line on the race track (not in the pit lane) after the race winner within 5 minutes.

Where the competitor is using a Power Supply provided by the Promoter/Circuit owner, under arrangement, the competitor must still ensure that the supply is controlled by an

RCD. However, in this case the responsibility for the provision and installation of the circuit breaker rests with the Promoter/Circuit owner.

Where the competitor is using a Power Supply provided by the Promoter/Circuit owner, under arrangement, the competitor must still ensure that the supply is controlled by an RCD. However, in this case the responsibility for the provision and installation of the circuit breaker rests with the

Promoter/Circuit owner.

Competitors must ensure that all that all cables, sockets and plugs used by them and their teams are in good and safe condition and free from breakages. Also that cable runs are kept to the minimum length possible and are positioned so as not to endanger, themselves, their assistants, other competitors, officials and spectators.

It is recommended that all electric cables, electrical sockets and plugs on electrical equipment used in the paddock, machine holding areas, the dummy grid, the grid and the designated pit area are of industrial type and waterproof. This will minimise the likelihood of the RCD on the power supply de-activating the supply due to fractures or adverse weather conditions.

Should the Clerk of the Course or the Appointed Safety Officers at an event consider a competitor or his/her team to be in breach of this regulation; the competitor shall immediately switch off all the electrical equipment and will not switch it on again until the breach has been remedied. Any competitor failing to do so immediately may be excluded from the meeting or subject to such other disciplinary action, consistent with the GCRs, that the Clerk of the Course and Stewards of the Meeting decide on.

MCUI SUPERSTOCK TECHNICAL REGULATIONS

(These regulations will apply to the follow Championships – Junior Superstock – Superstock 1000)

These regulations are the MCUI Superstock Regulations. The FIM regulations differ specifically regarding electronics and gearbox .We believe that Superstock regulations, as the name implies, should only allow limited modifications to the homologated machine.

EVERYTHING THAT IS NOT AUTHORISED AND PRESCRIBED IN THESE REGULATIONS IS STRICTLY FORBIDDEN

The motorcycles must be homologated by the original manufacturer only. The model will be eligible for Superstock competition for a maximum period of 5 years.

As the name Superstock implies, the machines used are allowed limited modifications. Most modifications that are allowed are only allowed for safety reasons.

Superstock motorcycles require FIM Homologation (see art 2.9). The MCUI/MCI may homologate machines, which comply or will comply with the principles stated by the FIM.

All machines must comply with all requirements of Road Racing as specified in the MCUI Regulations. The Appearance from front, rear and the profile of Superstock motorcycles must (except when otherwise stated) conform to the homologated shape (as originally produced by the manufacturer). The appearance of the exhaust system and engine case and tank guards is excluded from this rule.

1. Machine Specifications:

All items not mentioned in the following articles must remain as originally produced by the manufacturer for the homologated machine.

2. Balancing various motorcycle concepts:

In order to equalize the performance of motorcycles with different engine configurations, changes in the minimum weight can be applied according to their respective racing performances. The decision about applying a handicap system to a respective class will be taken by MCUI at any time. These handicaps will follow the system like described in 2.4.4.2 of the Superbike regulation, but will be adapted to the

Superstock class.

3. Displacement capacities:

The following engine configurations compose the Superstock 1000, Junior Superstock and Junior Twins.

4. Superstock 1000:

- Over 600cc up to 1000cc 4-stroke 4 cylinders maximum

- Over 750cc up to 1000cc 4-stroke 3 cylinders maximum

- Over 850cc up to 1200cc 4-stroke 2 cylinders maximum

5. Junior Superstock:

- Over 500cc up to 600cc 4-stroke 4 cylinders maximum

- Over 600cc up to 675cc 4-stroke 3 cylinders maximum

- Over 650cc up to 750cc 4-stroke 2 cylinders maximum

The displacement capacities must remain at the homologated size. Increasing the bore size to reach class limits is not allowed.

6. Minimum Weight:

- The FIM decides the minimum weight value for a homologated model as sold to the public by determining its dry weight.

- The dry weight of a homologated motorcycle is defined as the total weight of the empty motorcycle as produced by the manufacturer (after removal of fuel, vehicle number plate, tools and the main stand when fitted but with oil and radiator liquid at the prescribed level). To confirm the dry weight a minimum of three motorcycles are weight and compared. The result is rounded off to the nearest digit.

- The minimum weight value is determined by the dry weight value (in Kg.)

- minus 12 KG for Superstock 1000.

- minus 10 KG for Junior Superstock

- In the final inspection at the end of the race, the checked machines will be weighed in the condition they were at the end of the race.

- The established weight limit must be met in the condition the machine finished the race. Nothing can be added to the machine including water, oil, fuel or tyres.

- At the time of the event, the weight of the whole machine including the tank and its contents must be not less than the minimum weight, with a tolerance of 1 kg.

During the practice and qualifying sessions every rider may be asked to submit his motorcycle to a weight control.

7. Tyres:

All tyres must be treaded. Slick tyres are not permitted.

8. Carburetion Instruments / Fuel Injection System:

Carburetion instruments refer to throttle bodies and variable length intake track devices.
