OK Hobot, this is from Graeme Crosby`s memoir re high speed [motorcycle] flight...
"When you race at Bathurst, that 1st run down Conrod Straight is awesome. It is just one big long downhill stretch with 2 large humps & then a 90` corner.
The old nail [KR 750/3] was being timed at around 285 km/h in practice but just keeping it on the ground proved a problem with the aerodynamics. I had to pull myself up on to the tank & climb under my screen in an attempt to shift as much weight forward to prevent the wheel from comimg up. Having it in the air momentarily isn`t an issue, but it must stay straight while its up there. There is no guarantee that the bike will behave, so everyone used the same technique."
"The KR 750 went like 'shit off a shovel' - I blitzed the competition & was credited with breaking the lap record. There seemed to be an element of disbelief in the timing by some people. Just because the terminal speeds are high doesn`t mean the lap times are fast, because my KR 750 was no slouch across the mountain, making up for a lack of top-end speed down Conrod."
[TZ 750 was ~20 km/h faster there].
For myself, the old dirt bike learning of leap attitude control by a touch of rear brake always gives a certain confidence when the front rears up, but I get what you say about aero lift at speed compared to road feature & torque surge surprises.
