But I think best MPG results come from a low seat height in combination with a normal gearbox. Some losses in the CVT drive come from the rubber belt and are higher than losses from metal contacts like chain or gear.
Actually, on my bike , I think the exemplary sidewind self correcting tendencies result from a highish cg with low polar inertia about the roll axis due to my anchored tuck. As riders of high suspension adventure bikes such as the BMW GS will attest to. It is easy for changes in lean to arise from the various forces to immediately countersteer the wheels away from the wind. A smaller and more comfortable frontal area comes with the lower seat and feat forward position though.
