Question 1

1.0 GENERAL

Accepted Answer

1.1 Eligibility
All competitors must hold a valid competition license for Road Racing or Mini Bike / Pocket Bike Racing issued by the Auto Cycle Union.

ACU Pocket Bike Day Licence: 
Currently awaiting structure for 2026 but this has been granted.

!!!Attention for Ireland & Northern Ireland riders!!!
The review process is currently underway to determine who will issue pocket bike licences for residents in these locations for 2026. Historically, the ACU has issued these licences through an agreement with the Motorcycle Union of Ireland (MCUI). As the ACU only issues licences to residents in England, Wales, and Scotland, it is essential for residents to have the correct type of licence to ensure validity. During this review period, we encourage customers to contact the MCUI to request a pocket bike licence. The ACU is awaiting responses from the MCUI and ACU insurers to determine if insurance can be provided and licences can once again be issued through the ACU.
We highly value our customers from these locations and kindly request that you proceed with renewing your membership with BMB & renewal of the ACU Pocket Bike Licence while these issues are being investigated. Should MCUI and ACU be unable to reach a resolution, we will issue a refund of the membership upon request before Round 1.

Question 5

5.0 MEDICAL SERVICES

Accepted Answer

5.1 MEDICAL SERVICES. MINIMUM REQUIREMENTS FOR MINI BIKE MEETINGS

The minimum requirements for practice or racing to commence are as follows:
1 Doctor and 1 Paramedic, 2 Ambulances with 2 Ambulance Technicians
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 Doctor & 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. First aid 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 ACU Head Office as soon as possible of any concussion/suspected concussion injuries and then will subsequently:
a) Place the rider on the ACU Stop List
b) Inform Organisers of forthcoming events that the Rider has suffered a concussion/suspected concussion injury and is therefore placed on the ACU 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.

Question 9

9.0 MAXIMUM OUTPUT LEVELS AT A GLANCE

Accepted Answer

DYNO TESTING LEVELS FOR 2026 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.

Tolerances:
For the 2026 season, a “tolerance” has been added to BHP testing limits to account for minor dyno fluctuations and ensure fairness. Engines must be set to the Max BHP limit, not the tolerance.

If post-race checks find your machine outside the tolerance buffer, you will be suspended from this and previous races for this event only.

To compete in future races, your machine must be rechecked and shown to meet the power limits.

Please Note:
Allowed modifications to your engine or carburettor might push your output over the limit, risking exclusion.
As a result, if you plan to make these changes, we highly recommend having your bike checked with a basic power run by The Official BMB Dyno—either before the event or at the track—to ensure your engine remains within the required limits.
You are responsible for ensuring your engine meets all requirements. Setting limits is reasonable since everyone shares the same goal: affordable, fair, and enjoyable competitive racing.
