John, you missed out the ambidextrous catagory, I am mainly right handed but used to be able to write with either hand. Can't write with either now of course since all we do nowadays is type.................
Also if you're left handed how do you find using a throttle?
Usually on the right hand handlebar.......... No, sorry, it's second nature. It's just like me asking how do you use a clutch as a right hander? Both require an amount of finesse to use effectively.
