The Championship Dyno is a non inertia magnetic brake system which we have set at a release speed of 4kps. This allows us to compare bikes on a like for like basis with minimum stress on the already raced engine.  Please be aware that this limit is not a level that you can tune up to as Tuning is not allowed in a stock class. It is purely a tool to help the scrutineer easily detect engines that may have been modified beyond the items that have been allowed for the class concerned.

(Please note that the above limit is based on testing on the BMB Dyno only. It is likely that you will get a different reading on different dynos as they all vary considerably)

Max Compression (post race) = 8.5BAR / 123PSI

( A stock engine fitted with original gaskets and a standard non high compression piston will be within this limit set)

 

PLEASE REMEMBER THAT THESE STOCK CLASSES ARE DESIGNED TO KEEP THE SPORT AS CHEAP AS POSSIBLE AND OFFER AS CLOSE AS POSSIBLE RACING WITHOUT HAVING TO SPEND A FORTUNE.

  • CATCH TRAYS – All Supermoto Style bikes must be fitted with a metal catch tray that can hold at least 1.3 times the oil capacity of the machine it is fitted too.
  • RACE NUMBERS – Should be Clearly visible and be displayed on both the front number board and the side panels of the machine.
  • SEALED BELLY FAIRINGS – All Mini GP Style bikes must have the bottom Belly Fairing in place at all times and this must have a sealed section capable of catching the oil contents of the engine should it leak
  • EXHAUSTSAll Machines must have adequately packed and baffled exhuasts to obtain  an exhuast noise level of below 98db when tested on a track side drive by test and below 105db when tested in a static text. The Static test will be carried out with the Testing equipment held at at the same height and a distance of 1mtr and 45deg away from the exhuast of the bike and the revs at 5500 rpm as per MSA regulations. If a machine fails a random noise test it can be presented multiple time for rechecking but will not be allowed back on circuit till it has acheived a noise emmisions test below the required level.

SPECIAL NOTE

  • ONBOARD CAMERAS – As of 2017 onwards ALL on board cameras must be fixed securely to the bike and CANNOT be worn on the body or helmet. This is a stipulation direct from the Permit Issuers and has also been requested by the Insurers. Please make sure the camera is fixed in place before you take your bike to the safety inspection area.

STOCK CLASSES DEFINITION:

MISSION STATEMENT:

The Stock Classes have been developed to provide fair, affordable, and competitive racing for enthusiastic and like minded racers.

To provide a friendly, close knit environment for racers, where inclusion is the norm and family and friends can enjoy their hobby in a safe and well organised environment.

To promote racing on a level playing field where genuine talent is recognised and encouraged.

To promote enjoyable, close racing to a wider audience and encourage participation from further a field.

 

  • VALVES -These must be as supplied by the engine manufacturer and can only be replaced with a like for like product. You CAN Lap the valves in using a grinding paste but you CANNOT cut the valves in or re-seat them other than lapping in.
  • PISTON – Must be standard . High Compression pistons are not allowed.
  • GEARBOX – Must be as supplied as standard for your engine type and can only be replaced with a like for like component.
  • IGNITION – Can be replaced with a Lightened Inner or Outer rotor kit along with a lightened oil spinner if required depending on your class regulations. The oil spinner cannot be removed.
  • CRANK –  The Crank must remain STANDARD and must NOT be altered in anyway.
  • TIMING  – The Timing sprocket must be non variable but a variable stator plate may be fitted if required, unless stated otherwise in your individual class regulations.
  • CAM – Only either the standard Cam supplied with the original engine, a like for like replacement or a Z40 Cam. No other profile cam will be allowed
  • COMPRESSION – The compression level must be below the level set for the class and will be taken post race.
  • GASKET’S – Can only be replaced with a like for like product as supplied with your engine type. ie A Zongshen z140 gasket cannot be fitted on a YX 140 engine or vice versa.
  • MAX OUTPUT LEVEL – The maximum BHP Output level for the class is as tested on the BMB Dyno post race only. All Dynos vary so please do not take it for granted that your engine complies with this level  if tested on any other dyno.
  • EXHAUSTSAll Machines must have adequately packed and baffled exhuasts to obtain  an exhaust noise level of below 98db when tested on a track side drive by test and below 105db when tested in a static text.
  • MIXED ENGINE COMPONENTS – The engine must remain as supplied by the manufacturer and components from one engine cannot be used with another. For instance using a Z140 Barrel & Head on a YX 140 bottom end is NOT permissible. You can only install a replacement part that is like for like ie you cannot install a TB head on a Stock 140 or 160 engine.
  • MAXIMUM CUBIC CAPACITIES–  YX 140 & Z140 engines = 143.26cc / YX 160 engines = 160.4cc / Z155 engines = 155.88cc / YX 150 engines = 150.15cc / YX 88 engines = 88.90cc / yx 110 & z110 engines = 107.0cc. These figures allow a 0.025% tolerance over the actual capacity, this is to allow for the poor build quality of the Chinese engines used in the classes.
  • ENGINE SERIAL NUMBER- All engine serial numbers and markings must be present and cannot be removed.

 

SPECIAL NOTE

  • You are reminded that this is a budget sport and the above regulations have been put in place in order to maintain that. There may be products available on the market that fall within the above specifications that may cause your bike to exceed the stated limits for your class. It is YOUR responsibility to check that after installing these parts your bike still complies. 
  • The whole idea of a stock class is to, as far as possible in a budget sport, make the racing as close as possible. We have allowed various modifications in the regs above to try and accommodate as many people as possible, taking into consideration various items that may have been purchased, installed and available for some time at a reasonable cost.

 

THE “SPIRIT OF THE CLASS” RULE

We reserve the right to alter the above regulations so as to disallow any product or modification that may on the face of it comply but offer a significant advantage to the user.  Anything that is not mentioned above but is deemed by the organisers to not be within the class ethos will be disallowed and their decision will be final.

We all want close, cost effective racing not cheque book racing. 

Championship Rules & Regulations

The British Mini Bikes are authorised to hold Motorised events by the I.O.P.D. (International Organisation for Professional Drivers)

The IOPD are one of the twelve Governing Bodies appointed by the Department of Transport to authorise Motorised Motor Sport Events in the UK.

It is an OFFENCE under the Road Traffic Act to organise or take part in a motorised event unless it has been authorised and permitted by one of the twelve governing bodies.

In affect the Permit and Licence’s  Issued exempts the Organisers and Riders from prosecution for committing driving offences whilst taking part in an event.

The Organisers of an event are legally required to obtain this authorisation and permits by one of the governing bodies and to display these in a prominent place for inspection during rider sign on and whilst the event is being run.

To obtain the Authorisation and Permit, the tracks are submitted for inspection and the organisers have to run the meeting subject to strict guidelines set out by the governing body. Also the Organisers personnel are vetted, approved and licence’d for the roles they undertake.

All of the DofT appointed Governing Bodies operate a Licencing scheme for their events. When becoming a member with the British Mini Bikes you will be issued with an Annual IOPD Events Race Licence. If not a member you will have paid for a One Event Licence included in your entry fee, which will be issued to you at rider sign on. These licences mean you are exempt from prosecution for motoring offences whilst taking part in our events. This is extremely important as motosport is dangerous and in the event of a serious fatal accident, without this exception you could be prosecuted for the Offence of Death by Dangerous Driving.

BE SAFE

Make sure that any event you take part in is suitably permitted and authorised and that you have been properly licenced to take part. 

Any Organiser that puts on an event without the correct permit and authorisation is doing so at the expense of its riders well being and will be rendering both themselves and their riders liable to prosecution. 

Please dont take it for granted that an event is permitted just because the organisers say it is. Ask to see the permit issued by one of twelve governing bodies.

  3. A fire extinguisher will be available at the front of the Pitlane / Holding area and at all Marshall points.

CONTROL OF EXHAUST NOISE LEVEL

 

  1. ALL the circuits we race and practice at are under increasing pressure to minimise the noise emissions  and have in place a strict noise level. The BMB are now pro active in this field and have now enforced maximum noise levels for all bikes racing with us. This is in every bodies interests as failure to do so will lead to the loss of circuits to race at. 
  2. The Clerk of the Course will disqualify any machine which exceeds the maximum permitted sound level, or which in his opinion is deemed to be excessively noisy.
  3. Noise limit in force for all machines is a maximum of 98db when tested track side / drive by and 105dB at a static test
  4. For static testing 5500 rpm will be used. The noise test will be conducted with the microphone placed at 1 metre from the exhaust pipe at an angle of 45° measured from the centre-line of the exhaust end and at the height of the exhaust pipe, but at least 20 cm above the ground. If this is not possible, the measurement can be taken at 45° The driver shall keep his engine running out of gear and shall increase the engine speed until it reaches the specified Revolutions Per Minute (RPM). Measurements must be taken when the specified RPM is reached. Due to the similarity of the piston stroke in different engine configurations within the capacity classes, the noise test will be conducted at a fixed RPM. For reference only, the mean piston speed at which the noise test is conducted, is calculated at 11m/sec (4-stroke engines).
  5. A machine which does not comply with the noise limits may be presented several times at prerace control.
  6. A rider who’s machine fails a post race scrutineering noise test will be excluded from the results. At this final test, there will be a 3 dB post race tolerance.
  1. HELMETS – must have the latest ACU gold sticker or marked to comply with ECE 22.05 (the Euro equivalent). The helmet and visor must be in good condition and undamaged. If more than one helmet could or will be used during the meeting both must comply with these conditions and both must be presented for morning safety inspection.
  2. LEATHERS – Must be in good condition with no holes. Zips and fastening must work effectively and should be fitted with body armour and back protection. A separate back protector must be worn by all Junior riders and is highly recommended to be used by seniors also. Two Piece leathers can be used but must zip together correctly and be zipped together when riding.
  3. BOOTS – These must be full length (not ankle boots) and offer good protection with no holes or splits.
  4. GLOVES – These must be of good quality leather and fitted with adequate knuckle and wrist protection.

If after those 5 races no incident involving them has been reported to the Clerk of The Course or Race Control and after assessment they feel they are safe to ride, they will be granted permission to join the class permanently.
  • If you wish to move your child up into the next age group class prior to them reaching the required age limit, please email the organisers at info@britishminibikes.com. Please remember that moving your child up too early may result in a slowing in their progress rather than helping develop it.

 

NOTE –   Although we are keen to help develop young riders we MUST ALWAYS consider the following:

  • The upcoming riders safety and ability to compete
  • The existing riders in the classes safety 
  • The enjoyment of the sport and more specifically by the Senior Riders of the class the Junior is moving up into . They at no time should feel their enjoyment of their class has been compromised in anyway by the allowing of the younger rider to compete alongside them.

POST RACE SCRUTINEERING AND COMPLIANCE CHECKS

 

  • From March 2017 onwards a Random Inspection policy will be employed by a dedicated team. This means that regardless of your position within a race the scrutineer may randomly select you to attend scrutineering and have your vehicle inspected and possibly stripped. This is a method of making sure the classes are policed correctly with not just front runner vehicles checked but also vehicles from the front, middle and back of the grids. The Scrutineering officer may if deemed necessary ask the rider / team to remove the cylinder head etc. He will then check that the engine has not been modified and that it complies with your class regulations for your engine. He will then supply you with any relevant gaskets that may need replacing but will not refit any parts such as the head etc. If a rider refuses to strip there vehicle for inspection they will be excluded from the meeting and their points accrued to date removed from the championship table.
  • If instructed by the paddock marshall to report to scrutineering team, the rider must do so immediately before removing the machine from the Parc Ferme or Pitlane. Failure to do so will result in exclusion from the meeting and their points accrued to date removed from the championship table
  • When attending Scrutineering only the Riders being inspected or in the case of a Junior The Riders Parent, Gaurdian or Team member may be present inside the Scrutineering area. Failure to observe this may result in the exclusion of the rider concerned.
  • The Scrutineering Official will inspect your equipment as well as your machine  to make sure that everything complies with both the General rules and regulations and also the specific class regulations that the rider is taking part in.

 

They will Check all or any of the following

  1. A dyno run test for max bhp and also compare against data from a proven stock engine to highlight any abnormalities.
  2. A compression test to make sure that this does not exceed the stated limit for your class.
  3. Exhaust noise Level (a 3dmb tolerance will be allowed post race)

If the Head Scrutineer feels it necessary he will ask the Rider or Team to remove head and barrel and will check the following fall within the tolerances allowed for the engine type and class. The tools required for this will be available in the scrutineering bay.

  1. Cubic Capacity
  2. Visual Inspection of Crank
  3. Cam Profile
  4. Valves
  5. Port sizes

OFFICIAL COMPLIANCE PROTEST PROCEDURE

If at any time during an event a Rider or their representative feel that another riders vehicle may not comply to the class regulations, they can lodge an official protest.

The form (available at race control) must be completed and handed in to either the Clerk of the Course or Race Direction and must be accompanied by a £50 deposit. The riders vehicle will then be brought to scrutineering after the riders final race and they will be asked to remove the head and barrel. The vehicle will be checked to make sure it complies with the regulations and levels set for their class. If the vehicle proves to be compliant the rider will be awarded the deposit held. If however the vehicle fails to comply the protester will be refunded the deposit and the Rider will be excluded and their points removed from the championship table.

A Rider or Team can only lodge an official protest against a particular rider once per season. However other Riders / Teams are free to lodge a similar protest.
