When you arrive for any activity within the group, whether it is a ride out with your trainer or an organised run, please make sure that your motorcycle is maintained in good order and road legal. If for any reason it is found that this is not the case, you may be asked not to take part, and to remedy the situation before attending again.
This is not a case of the group "making silly rules". The fact is that if the worst happens it will reflect badly on RoSPA and undermine the standing of the Motorcycle section. It may also leave the trainer open to accusations of "abetting".
