This makes no sense to me, Amigo. At a given lean angle that angle from the CG to the road surface remains the same; however, the amount of movement increases the higher from the road surface you go. Therefor, the more movement available, the more control the rider has. CG height on a motor is somewhat overrated and has way more affect on vehicles with Ackermann steering and roll centers.
Balance a tall (high CG) broom handle on your finger.
Now balance a toothpick (low CG) on your finger.
Which is easier to control?
Food for thought:
Why do trials riders stand up on the pegs, raising the combined CG for better control?
