5.1 MEDICAL SERVICES. MINIMUM REQUIREMENTS FOR MINI BIKE MEETINGS

The minimum requirements for practice or racing to commence are as follows:

1 Paramedic,Ambulances with 1 Ambulance Technician

If one Ambulance has to leave the venue for any reason, the event can continue provided that there are a minimum of 1 ambulance, 1 Paramedic & 1 Technician present and available.

Whenever possible a First Aid Technician and a second Ambulance should be made available.

Ambulance A vehicle registered as an ambulance with the DVLA (Driver and Vehicle Licensing Agency) and registered with CQC if appropriate.

An ambulance must have an appropriately qualified driver to transport a casualty under blue lights. It must be equipped with the FIM minimum equipment regulations for a type C vehicle; that is:

Medical: A stretcher (preferably standardised), oxygen supply, apparatus to immobilise limbs and vertebral column. Firstaid medicaments and materials.

Technical: Radio communication. Visible and audible signals.

Staffing: An ambulance must be staffed by two First Aid Personnel (who can be the two minimum First Aid personnel).

An ambulance may act as a Medical Centre BUT if so it must be a vehicle in addition to the minimum ambulance requirements and must not be allowed to leave the circuit.

First Aid Personnel A person holding a current certificate of First Aid competency. (Where an event is open to the public event organisers should ensure that all First Aid personnel are insured against malpractice for the event concerned).

Special Notes

The minimum medical requirements specific for this discipline also apply to associated Test Days.

Concussion/Suspected Concussion

If a competitor is involved in an incident that results in him/her being diagnosed by the Medical Officer/Paramedic as suffering from concussion/suspected concussion, the rider is not permitted to participate any further in that event.Organisers are to notify IOPD Head Office as soon as possible of any concussion/suspected concussion injuries and then will subsequently:

a) Place the rider on the IOPD Stop List
b) Inform Organisers of forthcoming events that the Rider has suffered a concussion/suspected concussion injury and is therefore placed on the IOPD Stop List
c) Inform the Rider that he needs to see a Doctor and obtain a letter/doctor’s certificate that confirms he is fit to resume competitive racing/participate in a practice/test session.

The recovery time for anyone diagnosed with concussion/suspected concussion is as follows:

a) Over 20 years: Excluded immediately and suspended for a period of nine days.
b) 16–19 years: Excluded immediately and suspended for a period of twelve days.
c) 15 and under: Excluded immediately and suspended for a period of twenty three days.

The rider is not permitted to ride during the obligatory suspended periods outlined above and then only once he/she is in possession of a doctor’s certificate/letter after the suspended period has expired. A rider may be signed off to ride by the CMO at an event once he has observed the obligatory suspended period outlined above.

If a competitor has been injured on a Saturday and is suffering from concussion/suspected concussion, and the Organiser is aware that the rider was intending to ride or is scheduled to ride somewhere else the next day, the Organiser will inform the Organiser of the event being held the next day so they are aware of the rider’s injuries and as such he is prevented from participating in that event.

6.01 CHAMPIONSHIP STATUS

The Championship will be held under the auspices of the IOPD.

6.02 CHAMPIONSHIP ROUNDS AND VENUES

There will be a minimum of 5 two day events between March and October.

6.03 CIRCUITS

The circuit should be inspected and approved by the IOPD Track Inspector.  The minimum width should be 6 metres. The minimum length should be 500 with the maximum length to be set at the track inspection.

6.04 GRID AND STARTING NUMBERS

The grid should be set out during the track inspection, but should in principle be a 3 × 3  or 2 x 2 solo grid with 6 metres between each staggered rider. In principle the grid capacity should be a maximum of 28 machines with a 50% additional allowance for qualifying or practice unless the IOPD Track Inspector sets a lower limit during the inspection.

6.05 PRACTICE AND QUALIFYING

There will be a minimum of 15 minutes of practice/qualifying allocated to each class at each event. Participation in these sessions is compulsory for a minimum of 3 laps. On the 2nd day of a two-day meeting, a minimum of 8 minutes of practice must be made available to every competitor. Participation in the 2nd day free practice is not compulsory.

Testing or practice at the same venue is prohibited for the 72 hours preceding each championship round unless specified in class supplementary regulations.

Each grid will be set based on lap times recorded during each qualifying practice.

6.06 CHAMPIONSHIP LICENCE

Not Applicable

6.07 COMPETITOR TRAINING

As this is an entry-level to tarmac racing, no previous competition experience is required, but every competitor must attend a rider’s briefing and induction course before participating in their first event. Once the induction course has been received, a validation sticker will be added to the back of the competitor’s IOPD Licence.

DYNO TESTING LEVELS FOR 2024 SEASON

After extensive testing and data acquisition by ourselves and the official BMB Dyno operator, we have formulated the following bhp and torque allowances that we feel are fair for each of the controlled classes.

The testing procedure developed allows for all riders to be tested quickly in a like-for-like manner incorporating settings that make allowances for differing gear ratios, wheel sizes, tyre pressures, and atmospheric conditions.

Because of the nature of all the variables that are involved in Dyno testing, not excluding the different makes in testing equipment, all Dynos will read differently when testing the same machinery and, in some cases, quite dramatically.

However, by using the same equipment and type of tests at each event we can establish what is determined as a max level for the controlled classes we run when tested on the same settings.

To be deemed compliant your engine must not exceed the following maximum output levels for your class.

Be warned that any modifications (that are allowed for your class) that you make to your engine or carburettor may potentially push your output to just over this limit and therefore risk you being excluded. Therefore, if making these modifications we would strongly suggest that you have your bike tested by having a basic power run done by The Official BMB Dyno either before the event or at the track to make sure your engine still complies with these limits.

It is your responsibility to make sure your engine complies.

No one can really object to the setting of limits because after all, we all want the same thing.

Good Cost Effective, Fair, Fun competitive Racing.
