Rider Numbers

Your riding number will be issued by Ridernet when you get your MA Licence and should be used for all road races .

If you do not have a registered number (e.g. One Event Licences) then you can nominate a preferred number on your entry form.  However,  if your preferred number  is being used by another rider, you will be issued a different number in your final acceptance.

Stick On numbers can be bought in the office during rider sign in.  Make sure your background is big enough (see below).

Displaying Rider Numbers

The front number must be either in the centre of the fairing or slightly off to one side. Number plates must have a solid 10mm border.

Side numbers must be placed on both sides of your bike in a location that is clearly visible from the side and not obstructed by the riders legs (as per MoMS

  • Numbers can be on the fairing side panels, belly pan or sides of the tail piece.
  • Where there is no suitable location on body panels, number plates must be fitted.  These can be bolted onto brackets or zip tied to the bike as long as they are secure.  Edges must be safe and corners rounded. Mounting brackets must have rounded corners to prevent injury.
  • Number backgrounds can be oval or round as long as they meet minimum sizes.
    The minimum size Background for a 2 digit number is a rectangle 164mm high x 200mm wide
    The minimum size Background for a 3 digit number is a rectangle 164mm high x 300mm wide
    Note: the width can vary if the number contains a “1”
  • Advertising and designs on fairings must be kept 25mm clear of the background. If your fairing is the same colour as your background, you need to put a border around the background.
