Okay having had a day at 'The Track' in Portreath last week (my first time on a track on 20" wheels in over 20 years, why have I left it so long?) and then watching the National round at Bournemouth over the weekend my nipper is raring to go and wants to race. He's 5, what sort of helmets are these pin heads wearing these days? I've had a look around the net and aren't coming up with much.....MX stuff??
