Thanks for posting that one Dr, good to see he's got a few projects out back. Yeah I increasingly feel that racing motorbikes is not the smartest thing to be doing. The smart thing to do is like he says to focus on safety.
I have no neck brace, wear open face helmet, have body armour - whilst it has shoulder shields I feel that they offer little help, wear orthopedic sort of back brace belt, Knee pads - not braces, it's my boots that give the greatest confidence.
There is one other thing I do for protection, it's a saying; "Discretion is greater than valour."
