I had one a few years ago.£30 fine and the ticket lasted 12months.It just meant I couldnt go back on a certain quarry on my crf for 12months.Good policing there imo,there was about 7 of us all wearing proper gear and helmets and we had vans as transport not like some of them two up in "trainers n trakkies" they could of been real twats and reported us for insurance/licence offences .
On another note though,mate mate had one for starting his bike up in his front yard,he wasnt impressed and it was handed out by a pcso
