CHAMPIONSHIP REGULATIONS

Contents

1. Classes

Drivers may only race in one class for logistical reasons.
There are 3 senior classes for drivers in the year of their 16th birthday or older. Drivers in the year of 15th birthday may be allowed for experienced drivers at the discretion of the organisers:

  • Class 1 – Senior TKM
  • Class 2 – Senior Rotax
  • Class 3 – Senior Rotax 177

There is 1 junior class for drivers in the year of their 13th birthday up to 17.
Class 4 – Junior Rotax

1.1 Class 1 – Senior TKM

Engine

The only engine allowed is the commercially available TKM BT82 piston port 2-stroke engine in 115cc form. Engines must be fully compliant with the BT82 fiche, as published on the Tal Ko website. Engine temperature sensors may not be fitted during timed qualifying or race sessions.

The following exceptions to the fiche apply:

  • Fin rubbers are allowed but not required.

Weight

Minimum weight limits are for the complete kart including driver, safety equipment and fuel. Selected karts will be weighed in Parc Ferme at the end of each race.
All competitors must declare which engine type they are using on their race entry form. A competitor may change their restrictor type at any point in the weekend.
The following engine/restrictor/weight combinations are allowed. Details of the allowable restrictors can be found in the engine fiche document.

Minimum weight: 153 kg. Lower weights permitted using the TKM restrictor plates as follows:

  • 146 kg with blue restrictor
  • 139 kg with gold restrictor
  • 132 kg with black restrictor

Engine

The only engine allowed is the Rotax 125cc Senior Max, to Rotax specification and fiche, as published by Jag Engineering. Engines must be JAG sealed and the log book must be available for inspection at the request of the organisers. For the avoidance of doubt, both ‘Evo’ and ‘Pre-Evo’ components are allowed but the engine MUST still be specified to the fiche.

Weight

Minimum weight limits are for the complete kart including driver, safety equipment and fuel. Selected karts will be weighed in Parc Ferme at the end of each race. The minimum weights are as follows:

The only engine allowed is the Rotax 125cc Junior Max, to Rotax specification and fiche, as published by Jag Engineering.
Engines must be JAG sealed and the log book must be available for inspection at the request of the organisers. For the avoidance of doubt, both ‘Evo’ and ‘Pre-Evo’ components are allowed.

Weight

Minimum weight limits are for the complete kart including driver, safety equipment and fuel. Selected karts will be weighed in Parc Ferme at the end of each race. The minimum weight is as follows:

  • Junior Rotax – 145 kg

1.4 Further cost saving measures for Rotax classes

The below parts are ‘open’, i.e. they do not need to comply with the Rotax fiche. All parts must be of similar size and weight to those in the fiche, without any positive impact on performance and must not compromise safety in any way:

  • Radiator
  • Battery
  • Spark plugs – Rotax/NGK GR8D1 or GR9D1 or DENSO IW27, IW29 or IW31. Spark plugs must be unmodified with sealing washer in place.

1.5 Masters Classes

The below classes will each feature a ‘Masters’ sub-class for drivers aged 35 and over (including drivers who are in the calendar year of their 35th birthday). All drivers will remain part of the main class for both trophies and points and additional trophies will be awarded to the winning Masters, with separate championship tables.

  • Senior TKM
  • Senior Rotax
  • Rotax 177

1.6 Privateer Trophies

A trophy will be awarded to the top finishing privateer in each class at each race meeting. There is no privateer championship. Any driver paying for awning space and/or or team services, or receiving similar services free of charge is not eligible for privateer trophies. Drivers are required to confirm their privateer status each time they enter a race meeting. Driver eligibility is at the discretion of the organisers.

1.7 Number and background colours

Each class will use the below combination of number colour and background.

  • Junior Max – Red background/White text
  • Senior TKM – Red background/White text
  • Senior Rotax – Blue background/White text
  • Rotax 177 – Green background/White text

2. General

2.1 Fuel

Only premium or super unleaded pump petrol may be used, along with castor based 2-stroke oil for TKM and any suitable oil for Rotax.

2.2 Chassis

Chassis choice is open with no restriction on removable stiffening bars, number of axle bearings or castor/camber adjustment. Chassis must have been previously homologated by a recognised governing body and for reasons of safety, be without significant modification from its original state. If in doubt as to chassis eligibility, competitors should check with the organisers.

Fully enclosed chain guards must be used, with added protection to prevent finger contact with the chain and engine sprocket where not covered by the chain guard.

A maximum of 1 chassis is allowed to be used at each race meeting (excluding practice sessions). Chassis numbers must be recorded in the Alpha scrutineering system.

2.3 Engines

A maximum of 2 engines are allowed to be used at each race meeting (excluding practice sessions). Engine numbers must be recorded in the Alpha scrutineering system.

2.4 Tyres

  • Slick Tyres – Maxxis Sport
  • Wet Tyres – Maxxis SLW

Slick tyres used for racing must be purchased from Dartford Karting (https://kartstore.uk/shop.cfm?cat=1530&item=10425) and must have both a barcode and a laser-etched copy of the barcode as shown below.

It is the competitor’s responsibility to ensure their barcodes are added to the NKC database. Details of how barcodes will be added to the database will be published before each round. All drivers may use a maximum of 2 sets of race slicks for the season, one set for the first three rounds and one set for the final three rounds.

Slick tyre condition will be continuously monitored throughout the season and the organisers may elect to allow the purchase of an extra set should degradation be higher than expected. This would be confirmed by the publishing of an official regulatory update.

Usage restrictions apply to race sessions only. Competitors may use any tyres of their choice in practice sessions.

There is no restriction on the number of wet tyres used over the course of the season. Wet tyres may be purchased from any source.

Slick tyre barcodes will be recorded and checked in pre and post-race scrutineering. Competitors found racing with non-compliant tyres will be excluded from the session.

In the event that a slick tyre needs to be replaced due to damage, the tyre must be presented to the organisers/scrutineer after the race session and BEFORE you leave parc ferme. The organisers will decide whether a valid claim for damage is reasonable. If it is, a replacement may be purchased. If the tyre is new, you must put sufficient wear on the tyre and present both tyres to the organisers for comparison. Once accepted, the tyre database will be updated with the new barcode.

Examples of damage include puncture, bead damage resulting in failure to hold pressure (bead sealer must be tried first), significant cuts due to contact, etc.

Accidental damage from over-inflation or from fitting/removing tyres will not be accepted unless the tyre has NOT been used in any race session.

Excessive wear due to normal use or poor kart setup will not be accepted as evidence of damage. In such a circumstance the competitor may seek approval from the organisers to replace the tyre(s) to enable them to continue racing. However, this will result in instant disqualification from the championship and the driver will not be eligible for trophies.

There is no restriction on tyres used for practice.

Tyre softening is NOT permitted. NKC has a “tyre sniffer” and will check tyres both before and after races. If when compared with other competitors a significant difference in readings are identified, you will be disqualified and tyre barcodes removed from the database. NKC’s decision is final.

The penalty for deliberate non-compliance with the tyre regulations will be disqualification from the championship and refusal of entry to future events.  Costs will not be reimbursed in this circumstance and the organiser’s decision is final.

2.5 Tyres for new drivers round 3 and 6

If a driver is racing either at Round 3 or Round 6 and are on a new set of tyres as it’s their first round, they MUST use their tyres for a minimum of 4 practice sessions on either the Friday or the Saturday and report to the dummy grid marshal who will mark down each session you complete. They must complete 75 % of each practice session. If it is raining or forecast to rain, it is the driver’s responsibility to ensure tyres have been through the required heat cycles either by practicing Friday or else electing to register a used set with the organisers at our discretion.

2.6 Safety Equipment

TaG and clutched engines must have an engine off switch or button, positioned in a prominent position, with the off position clearly marked ‘OFF’. Applies to both TKM and Rotax classes.

The following safety equipment must be worn during all practice and race sessions:

  • Helmets: CIK/MSA/ACU/Snell specification racing helmets or UK road legal motorcycle helmets.
  • Suits: CIK homologated with no limits on homologation date.
  • Footwear: Racing boots with ankle protection
  • Gloves: Racing gloves

All safety equipment must be in good condition with no significant damage that would reduce the item’s ability to protect the driver.

2.7 Cameras

Helmet mounted cameras are not permitted. Cameras may be securely mounted to the kart, at the discretion of the officials.

2.8 Eligible Drivers

The organisers may ask for proof of age at any time. All drivers must declare their date of birth when registering and drivers under the age of 20 must provide proof of age at the same time.

No racing licence is required and first time racers are welcome, but basic competence is essential. Driver competence will be continuously monitored. In the unlikely event that a driver falls below the standards of a safe racer, they will be prevented from continued participation in the event and asked to demonstrate their competency before being allowed to enter future events.

Novice drivers are welcome to elect to start any race from the back of the grid should they wish, subject to providing reasonable notice. The organisers may compel a driver to start from the back should they deem this is required for safety reasons.

By signing on to an event, drivers declare that they are fit to race and free from any condition that could impair their ability to drive and race safely.

2.9 Dummy Grid & Race Start

Numbers on the dummy grid are strictly limited to driver +1 assistant. Once the kart is on the floor it is under parc ferme conditions and may not be worked upon without the express permission of the grid marshal. Karts should be on the floor in their dummy grid spot at the latest of two minutes before their race or whenever the grid marshal signals. Minor work to resolve engine starting failures will normally be allowed.

If there is an unexpected delay due to the weather changing, the grid marshal may signal a pause to parc ferme conditions, at which point karts may be returned to trollies to be worked on by driver and their assistant. A time limit will be given and any competitors not ready to take the start will be excluded. Unless express permission is given by the grid marshal, only the driver and their assistant may work on the kart. The only changes permitted when there is a change in the weather are as follows:

  • Tyres
  • Rear width
  • Rear bumper adjustment

If the competitor directly in front of you on the dummy grid oils up, retires, or does not start from the dummy grid/grid, then you are permitted to fill that gap and form up behind the competitor that was directly ahead of the competitor that is missing. If the missing competitor appears during the rolling lap, then you must make space in front of your kart to enable them to take their rightful position. It is the driver’s responsibility to make it back to their rightful position in a safe manner (hand up to show you are out of position and not making contact with anyone whilst coming through the field) up to the position of the first yellow flag, which will normally be waved in the final series of corners before the start/finish straight. Use of circuit cut throughs to catch the pack up on the rolling lap is prohibited unless directed by a marshal.

Weaving is allowed in moderation. If you spin, we will not wait for you. If you cause an accident, you will receive a one-lap penalty. Drivers must still leave enough space for drivers to come through who may be out of position.

Pole position driver for each race sets the pace for rolling laps, and drivers must stay in formation within tram lines on the lead up to the start line until the lights go out and the race begins.

2.10 Scrutineering

Competitors must present their kart and safety equipment for scrutineering prior to racing as prescribed in the final instructions which will be issued in the days preceding the event. All equipment must be in a safe condition to use, which will be determined by the official scrutineer on the day.

2.11 Parc Ferme – Post Session

Following each qualifying and race session selected drivers will be guided to the Parc Ferme scales and compliance checking area. These drivers will be weighed and may undergo further compliance checks. Any driver found to be non-compliant with any technical regulation will be disqualified from the race. Any driver found to have deliberately cheated may be handed a further penalty ranging from points deduction to expulsion from the championship.

2.12 Detachable Front Fairings (Drop down nose cones)

All classes will be required to use CIK detachable front fairings. These will be checked in Post Session Parc Ferme and the penalty for an out of position nose cone will be +5 seconds added to the competitor’s race time, which will be used to determine their finishing position. Please note that competitors remain subject to driving standards penalties as awarded by officials during the race, regardless of the status of the nose cone.

Competitors must not attempt to re-position their bumper at any time until released from Parc Ferme. The penalty for doing so will be disqualification from the meeting.

3. Sporting Regulations

Regulations will generally be in line with the MSUK Blue Book Section U: Karting. Where there are contradictions, the NKC specific regulation takes precedence.

Racing will normally consist of 3 heats and 1 final. The grids for the heats will be drawn, with each driver given front, middle and back starting positions. Points accrued in the heats will determine the grid for the final. This race procedure is subject to change due to local time pressures/weather/daylight, etc.

3.1 Scoring

Points will be awarded based on finishing positions in all races as follows:

  • 1st – 50
  • 2nd – 48
  • 3rd – 47
  • 4th – 46
  • 5th – 45

And so on…

Double points will be awarded in the final. Trophies will be awarded for the top 3 finishers, though further trophies may be awarded at the discretion of the organisers.

Masters drivers will be identified in the tables and championship trophies awarded accordingly.

Guest drivers will not be awarded championship points. Points for other drivers will be awarded as though this competitor is not present.

Any competitor (whether guest or registered) entering the final round having not raced at any previous round will not be awarded championship points. Points for other drivers will be awarded as though this competitor is not present. All drivers will be eligible for that meeting’s trophies.

If two drivers end on the same points after the final round, the championship will be decided on the number of final wins. If still the same, race wins will be counted.

3.2 DNS

No points will be awarded for a non-starter.

3.3 Dropped Scores

Every driver will drop their 3 lowest scoring heats and 1 lowest scoring final from their championship points tally.

3.4 Race Numbers

Your chosen race numbers must be displayed on the front, rear and both sides of the kart during all practice and race sessions.

3.5 Seeded Numbers

Drivers finishing in the top 10 of the previous year championship will be eligible to run their finishing position as their race number for the current year championship if desired.

3.6 Transponders

Transponder type is AMB/Mylaps at all rounds. It is the competitor’s responsibility to ensure they have the correct transponder type at each event. Transponders may be available to hire but this is not guaranteed. The organisers will provide information on this prior to each event.

Transponders must be mounted to the back of the seat. The competitor will be responsible for the safe return of any hired transponder and will be charged for any damage or loss. Transponder hire is £15 for the weekend. Drivers who do not return their transponder at the end of the event must return the transponder by post the following day or they will be invoiced for £350 for the replacement transponder.

In some cases, it may be necessary for hired transponders to be shared between classes. It is the competitor’s responsibility to ensure their transponder is fitted prior to their race session.

3.7 Flags

All drivers must be aware of the flags and what they mean. In 2o24, the use of the yellow/black quartered flag otherwise known as the battenburg flag may be used.

Yellow

Danger ahead. Slow down. No overtaking.

Drivers MUST lift off and be prepared to suddenly change from the projected racing line, or take other evasive action including stopping if necessary.

Racing can only resume once drivers have passed the incident or they have been shown the green flag.

Green

All clear, at the end of a danger area controlled by yellow flags

Also used to signal the start of a formation lap and shown at all posts during first lap of each practice session and during the formation lap.

Blue

Stationary – a driver is approaching to lap you.

Waved – a driver is about to lap you. Allow them (and following drivers if applicable) through.

Red

Immediately cease driving at racing speed. Proceed slowly, without overtaking, and with maximum caution to pits or start line obeying marshal instructions, and being prepared to stop should the track be blocked.

Chequered

End of race or practice session

Green and yellow chevron

False start. Slow down and reform the grid. Continue on another rolling lap, stay in formation at the speed set by the pole sitter at the front.

White

A service car or slow moving kart is on the circuit. The flag will be waved to indicate the sector of the track that the slow moving vehicle is in.

Yellow and red stripe

Slippery surface ahead.

Yellow and black quartered (Battenburg)

Immediately slow down and form up behind the leader, no overtaking. Continue at a reduced pace, with no overtaking until a green flag is shown at the start finish line. The race leading kart must slow down to a steady pace (as on a rolling start lap).

Black and white diagonal

Warning to the driver identified by number that their behaviour is suspect and that they may be black-flagged on further reports.

Black and orange circle

Mechanical flag warning of problem with kart that might not be obvious to the driver. The kart concerned must return to the pits that lap.

Black

The driver must return to pit within one lap of receiving the signal and report to the clerk of the course if called. A penalty of exclusion may be enforced.

4. Judicial

NKC is strictly non-contact and competitors are required to show respect for their fellow competitors and officials at all times.  Deliberate contact will not be tolerated and will be dealt with severely.

The following are examples of incidents and guideline penalties, though actual penalties will be at the discretion of the Clerk of Course:

4.1 Penalties

  • Driving in a manner incompatible with general safety: +1 lap or race disqualification
  • Contravention of a flag signal before or after a race: +5 seconds
  • Causing accident on rolling lap: +1 lap
  • Contravention of a flag signal during a race: +10 seconds
  • Ignore technical flag twice: Black flag
  • Ignore black flag more than once: Race/meeting disqualification
  • Abusive language/behaviour or assault: Race/meeting/championship disqualification
  • Failure to attend driver briefing: Fine of £20 (donated to charity)
  • Failure to obey the instructions of an official: Race/meeting disqualification
  • 3 GUA penalties in 1 season: 10 point deduction from championship tally
  • Each additional GUA: 10 point deduction from championship tally or 1 race meeting ban at Chief Steward’s discretion

  • 3 race DQs in 1 season: Championship disqualification and race bans to be decided by the organisers
  • Illegal re-positioning of drop down nose cone or attempting to do so: Meeting disqualification

4.2 Judicial procedure

The Judicial Procedure is as follows:

  1. Circuit Marshal/Observer reports incident to Clerk of Course. The Clerk of Course may also act on an incident only witnessed by him/herself.
  2. Clerk of Course reviews incident and decides on penalty.
  3. Competitor accepts penalty or requests an incident review using the procedure below.
  4. For penalties given in A Finals only, competitor’s may exercises their right to appeal.
  5. There is no right to appeal penalties given during heats.
  6. Ideally any appeals will be decided prior to the trophy presentation, but where there is insufficient time the Chief Steward may elect to review the appeal after the event. Where the outcome affects the trophy positions it may be necessary to postpone the trophy presentation until the next meeting.

4.3 Incident review procedure

NKC will review all incidents, if requested, where evidence is available. To request a review:

  1. Complete incident review form – collect from office or scrutineering.
  2. Driver or representative to go to race control.
  3. Assistant steward will come out and take your form and discuss the incident and/or view evidence if needed.
  4. Leave and continue with your day. Assistant steward will relay information to chief steward for review.

Once review has been completed, one of the following will happen:

  • An alteration in the official results.
  • No further action.
  • If necessary, the chief steward may call drivers to race control to gain further information or discuss further.

There will be no further discussion other than an official appeal (which is only allowed for incidents in A Finals).

We will message you direct on Racehub with outcome.

4.4 Appeals procedure

  1. Stage 1 – Driver confirms their intention to appeal within 15 minutes of the publication of the official results and provides supporting evidence to Chief Steward. Chief Steward reviews evidence and makes their decision to either uphold the penalty, give an alternative penalty (which could be higher or lower) or dismiss the penalty altogether. Driver accepts Chief Steward’s decision or confirms they wish to move to Stage 2.
  2. Stage 2 – Driver pays £20, which will be donated to Cancer Research UK regardless of the appeal outcome. Evidence of the donation will be provided. 2 drivers will be selected at random to act as Judges of Fact. Drivers will be selected from a different class from the appellant.
  3. The Judges of Fact will hear from both the Chief Steward and the driver and review evidence where available. They will then confer privately and decide on whether to uphold the penalty, suggest an alternative penalty (which could be higher or lower) or dismiss the penalty altogether.

APPEALS

Results of appeals can be found below.
