Ah well I don't do 'high speed' any more, my next bike was made in 1953 in Plumstead with drum brakes, and doesn't need tax or an mot.From experience, air bag vests are a huge step forward in rider protection. I've had the misfortune to test mine on two occasions, both high speed, I've also had similar crashes with regular armour (the good stuff too) I'll take the airbag vest anyday of the week.

I wear the armoured stuff these days, which is a step up from the t shirt and patch of my youth. That'll do, at 60 I don't really care any more.
