It's a discussion with an enjoyable and infinite amount of input/info available - If tyres, suspension and bhp are the most important then how come there's such a small gap between a Superstock and Superbike especially as Stocker's don't change tyres ?, is it better to be on a machine that possibly moves around under you more but gives more feedback ?, is it more of a challenge to deal with your machine's reaction to bumps at a slower speed or the bigger commitment/speed and lean angle involved with a smoother surface?. Like Nick says the riding style back in those days was totally different - would you be able to use the lean angle/grip/stiffness benefits of a slick tyre over the bumps/surface of that era ?. Another question for Nick - Did the works/factory bikes of those days have trick/non retail suspension and tyres that weren't available to the other riders ? and were there the aftermarket suspension companies and components around in those days ?.
