I just got back into couple of months ago, did it late 70s-80s. Probably one of the cheapest motorsports to get into, picked up a Montesa 315 for 900 and a trailer for 150, still had my old boots, helmet was 45 and I just wear my mtb jacket, gloves and tracksters. Two local clubs have a trial each per month, 10 entry fee and 1/2 gal of fuel :-)
