I have a Concours which I keep in Florida and another which I keep in England. The Florida dealer inflated my tires with nitrogen whereas my british bike is inflated with air. Cold pressures are 42 front and rear but I notice that when I have been riding in England the pressures can reach as high as 45 whereas in Florida they barely move. Now presumably Kawasaki know that 42 cold can reach 45 or higher when ridden hard and are happy with this state of affairs. How can this be reconciled with the fact that my Florida pressures don't move? Does it mean that in Florida I am riding with pressures that are too low? Or is it all a red herring as the rubber warms up just the same and the pressures don't matter. Any thoughts you technical guys.
