New members.

If you have no machine when you joined, find out what is acceptable within our cut-off dates. Only the committee can assist you with this. Their names appear on the front page of the website.

  1. First you must bring your machine and riding kit to a practise, usually at Midvaal because of its easy location to us all, before doing anything else. 
  2. Malcolm Tutt or Trevor Williams our ‘A’ grade MSA scrutineer who has in the past scrutineered and passed the World SuperBikes when they come here, will check your bike and riding kit over and give you a list, if needed, of things he wants corrected. His word is law as far as bike safety, riding kit etc is concerned and nobody including the committee or chairman can override his decision. 
  3. Assuming the bike is rideable and Trevor allows you onto the track, you will ride with at least two committee members so we and you can get to know each other as to riding style, abilities etc. 
  4. Once all the above has been complied with Terry Barson or such committee member who is instructed to issue a ‘racing number’ will then provide you with a unique number that must appear on the front and sides of the machine.   
  5. You are then welcome to ride in any event and or practise we organise. 
  6. At every event we take part in, Malcolm or Trevor will scrutineer your machine prior to going onto the track. No scrutineer sticker, no ride.


Rules and regulations not finalised as yet.
The Historic Motorcycle Group, which is currently “demonstrating” race orientated bikes up to December 1975, have instituted an additional group called class B.

Class B.

This class will cater for any bikes, racers, or standard bikes (limited modifications) up to December 1983. The current bikes up to December 1975 will be known as Class A.
The aim of this is to dust off that old bike in the garage, shed or museum and join us.

HMG currently visits all the race tracks in the country.
This is not a championship or series with points or trophies. We are just a bunch of guys having fun whilst going fast in a safe track environment.
We do not want any wild eyed maniacs riding with us due to the probable speed differences.

Safety rules regarding overtaking and track etiquette will apply.
HMG is run by a committee which will monitor and scrutinise both bikes and riders.

Please visit our website for rules, bike eligibility and contact numbers.
