Yup, less leaning required.

just thinking out loud, perhaps for crosswind you want the fore-aft cg to align with the cp. But you want the cp to be be as low as possible with the cg as high as possible (with the least frontal area too and weight a secondary consideration).

Some discussions say to have a more forward CP, as the effect is somewhat self correcting? But at very high speeds (i.e. bonneville) this sounds unnerving to me, dunno, maybe the fast spinning wheels help.

Yahoo! Groups
"If a cross wind pushes the rear of the bike off line, it will be similar to
a dirt track power slide which could lead you to places you don't want to go
unless you can correct out of it.

Conversely, If a cross wind pushes the front of the bike off line, the
steering will be moved which will trigger an automatic correction.

This is exactly what I experienced in the ECO with 50MPH cross winds on
three different howling windy days. The ECO has more "sail" area in the
front than the back. It immeadiately causes a steep lean toward the wind
just as it would on your typical motorcycle."
