[QUOTE="Andrew"] However, in the case of a motorcycle, unlikely.[/QUOTE] Careful, you're painting with a very big brush. I've been through four bikes, (all different flavours of yamaharleys, plus one Kawasaki of a similar theme), non have been closer than 5Km/h at any useful speed (above 40), and at least one of those edging close to 10Km/h off towards the windy part of the scale. And as per usual, none of them read slower than actual.
