I'm a motorcyclist, weekend warrior if you like
It makes you a better car driver, just like being a cyclist does.
The training received nowadays(and the current test) drill this into you
(sorry MF & Grips, 's true)
However, when I was 17 you just rode round the block twice without falling off to get your licence. Maybe this is where the "born agains" are lacking, as when they come back to the scene they either go HD-type pipe and slippers, or the sportsbike route. It's tempting to push the things beyond your skill level, and in support of that side of the argument I would agree that the modern machine is much more capable than 99% of riders.
But there's an element of truth in what TJ and PP say – some things may look scary to the uninitiated, but that 1% know what they are doing. In the same way that some of the MTB stunts you see look terrifying, but you know obviously that the guys concerned can pull it off – and on your bike too.
The public roads however are no place for scaring people, even if you know what you're doing.
great thread though
