[QUOTE="Muck"] [QUOTE="Krusty"] I've just leant over while standing on the scales, & I didn't get any heavier. Therefore you're obviously talking bollox![/QUOTE] You're not going round a corner on those scales. If, on the other hand you were leaning at 45 degrees and being accelerated at 1.4G[1] then you would be back in a steady state, until you stopped accelerating and fell over.[/QUOTE] So we're talking about the effective increase in gravity in the plane of the bike/rider due to centrifugal force (whether or not centrifugal force actually exists), yes? In which case I don't see where the 1.4G comes from, as surely it's not a fixed figure, but one that depends on the speed you're going? The extra weight whilst leaning at 45 degrees at 150mph will be much higher than at 20mph. If it's physically impossible for there to be less than 1G acting on the plane of the bike/rider at any speed/angle, then I'll concede. In fact I'll concede anyway coz it's not something I want to be thinking about at bedtime :-)
