Vehicle Classes

This is an extract from the current (2009) Standing Supplementary Regulations (SSRs) and, whilst every effort has been made to ensure consistency, the wording of the published version takes precedence over this website version at all times. The MCC also imposes tyre regulations for all classes. Refer to the published version of the current SSRs for full information.

Motorcycle and Three Wheeler Classes

CLASS A – Single or Multi Cylinder Solo Motorcycles of British Manufacture, (Engine and Frame).

CLASS B – Single or Multi Cylinder Solo Motorcycles up to 450cc.

CLASS C – Single or Multi Cylinder Solo Motorcycles over 450cc.

CLASS D – Motorcycles with Touring or Trials Side-cars, (Scooter Side-car outfits are NOT eligible).

CLASS E – Three-Wheelers. Three-Wheelers must comply with the following requirements:
a). Seating must be side by side. Passengers must remain within the seating accommodation of the vehicle.
b). Must have a floor of metal or other substantial materials, and be surrounded by body sides to a minimum height of 12 inches above the uncompressed seat cushion.
c). The drive may be either shaft or chain, driving one wheel only, or two wheels via a differential which is NOT a torque biasing device.
d). Engine capacity is limited up to 1300cc.
e). Must be fitted with a Towing attachment.
f). Three-wheelers will be placed in the running order of the event with the car classes, to assist with recovery.
g). Details of Non Production home built specials must be submitted to the MCC for approval and an acceptance certificate.

Rigid sidecar outfits and early Three-wheeled Cyclecars may apply to the MCC for a classification certificate that will allow them to compete in conditions that conform to the age of their vehicles and these conditions will clearly be shown in the Final Instructions.

Copies of the agreed specification for each car listed in Class 7(c) are obtainable from the General Secretary. Variations to these specifications may only be made in compliance with the Motorsport UK Technical Regulations M 6.2 to M 6.10. The list will be kept under review and other cars may be added after a submission by the manufacturers, Owners Club, or any owner to the Motorsport UK.

Vehicles with current agreed specifications include: Allard J1, Buckler Mk5 and 6, Buckler type 53, Burlington-Arrow, Dellow Mks 1 to 3, Dutton Phaeton and Melos, Dutton Sierra Estate, Fergus Mosquito, Jago Jeep, Liege, Marlin-Roadster T,M, and TM versions, JC and MJ Midge, NGTA, Racecorp LA Roadster, Rickman Ranger, Siva Edwardian Roadster, Spartan Roadster Mks 1 to 6, Swindon Vincent Roadster MPH and Brooklands, Teal type 35, Tempest 850.

a) Non-production cars.
b) Rear Engine Cars. (except vehicles in classes 4, 6, and 7).
c) Front engine cars manufactured on a limited basis (except those in Class 7).including those which:
1) have the rearmost part of the front seat cushions(s) rearward of any part of the rear tyres and
2) have a wheelbase less than 90 inches (228.6cm).

a). Any vehicle is eligible, subject to ‘d’ below. (Subject to acceptance by the Clerk of the Course.)
b). The class will be competing on a modified course of a less damaging nature.
c). Entrants will NOT be competing for any of the awards under SSR ‘G’.
d). The vehicles must comply with all other SSR requirments.
e). For practical reasons it may be necessary to limit entries in this class.
f). Suitable awards will be presented to competitors in this class.

Exceptionally, and at the Club’s discretion, historically interesting or traditional trials cars, or other cars which have a recognised disadvantage or advantage in their defined class, may be reclassified. On the basis of their performance, or potential performance cars may be placed in a nominated higher or lower class. Competitors wishing to make use of this discretion must apply to the General Secretary with the full specification of their car and the justification for inclusion in a nominated Class. The Club will issue a Reclassification Certificate to accepted cars which will be valid for one or two years in the first instance and be renewable at 2 yearly intervals thereafter. Conditions may be attached to the certificate.

To celebrate the Exeter Trial’s 90th anniversary the MCC organised a separate ‘Run’ which took place alongside the actual trial but used only hills of a totally non damaging character. These had figured in past trials but by their nature were no longer difficult enough to be of interest to present day competitors. This event-within-an-event was an immediate success with competitors asking for more of the same and from this was born our present Class O.

This is an entirely separate class in each of the three MCC classics. It is part of the main trial using a similar route but deviating to take in easier hills, usually with a historic MCC background, and a shorter night road section. Unlike the regular classes with gold, silver and bronze medals, plus class and overall awards, there are no prizes here other than for finishing without penalty which means that no competitor’s success or failure can affect another. This takes us back to the basis of all MCC trials which is for the competitor to be pitting his skills against the club.

Anyone in any type of car or motorcycle can take part in Class O and consequently it appeals to many for whom the general classes might be too competitive. These competitors may be people who are newcomers wishing to dip their toes into the water before tackling the real thing or “Oldies” who still enjoy being part of an MCC event but for whom age or health presents a problem. The class also appeals to owners of old, interesting but fragile, machinery which could not cope with the hurly burly of today’s sections but which would be perfectly at home with the less damaging hills of, say, fifty years ago. Competitors on two, three or four wheels all run together in true MCC manner, the club being one of the very few where drivers and riders rub shoulders.

It would be a mistake, though, to think that Class O is merely a nostalgic social run in interesting countryside. All the hills have a sting in them. Some are surfaced but have enough gradient and corners to make drivers think, particularly when faced with a restart on the most difficult bits. Those that have gravel or muddy surfaces, although not rough and damaging, are “stoppers” in their own right ensuring that vehicles should be carefully prepared and competently driven. To claim a Class O award for a faultless performance, which appropriately takes the form of an MCC medal cast from genuine Cornish tin processed from our own Blue Hills Mine, is no mean achievement.

The introduction of Class 0 has certainly added a new dimension to the three MCC Classics, allowing fifty or more members each time to sample the action rather than having to stay at home regretting their inability to compete due to age, lack of experience, or possession of suitable machinery.

Variations from the ACTC Vehicle Class system

Members who are considering competing in events organised by other ACTC member clubs should be aware that there are subtle variations between the current MCC vehicle classes and the current ACTC vehicle classes. These are listed below:

  • Class 3: The ACTC does not allow front-engine front-wheel-drive cars with limited slip differentials (and similar) into Class 3. These vehicles must run in Class 6 in ACTC events.
  • Classes 6(b) and 7(b): The ACTC Rules are much more restrictive about the use of limited slip, or similar, differentials in these two classes. Refer to the ACTC website for more information.
  • Class 0: The ACTC has no direct equivalent to MCC Class 0 although some ACTC clubs run events which include a ‘Class 0’. The requirements may differ from club to club and careful reading of the SSRs for each event will be required.
  • Reclassification Certificates: MCC Reclassification Certificates are not accepted in most ACTC Championship events, although some ACTC clubs run non-Championship events which do accept them. This will always be stated in the SSRs for the event.

All motorsport in the UK is run under the control of either the Motorsport UK, for car events, or the Auto Cycle Union (ACU), for motorcycle events, and those competitors with licenses issued by either organisation receive a copy of the relevant organisation’s regulations.

The MCC chooses, however, to run all its events under permits – Clubsport (Motorsport UK) or Restricted Permit (ACU) – which do not require competitors to have competition licenses. The MCC is also unusual in that we provide events which cater for competitors on 2, 3, or 4 wheels. It is therefore necessary for the Club to publish its own Standing Supplementary Regulations (SSRs) which include regulations extracted from the handbooks of the two national organisations, and regulations pertinent to the unique nature of the MCC events.
