First quiet moment you get call in a newsagents pick up the latest MCN (motor cycle news) ,a weekly motorcycle newspaper, find a quiet pub and get an 'English' beer, towards the back of the paper is a weekly events list.
+1 for the Motorcycle Museum in Birmingham, you could do it in a day by train if no car, Birmingham International station is close by, not been myself since the fire. Also consider Sammy Miller Museum in Hampshire near to Beaulieu but a distance from London and travel links not good.
