I know some here are not keen on Guy Martin but I see from the current Classic Motorcycle that he managed to finish the Scottish Pre-65, riding an Ariel (which looks very standard from the pic in the magazine). He came home last - the 157th finisher.
I used to ride an Enfield Bullet in pre-65 trials and I know just what hard work these old bikes are. So I say congratulations to him - I look forward to seeing the TV programme!
