Loosing weight alone may be slightly more efficient, but the main reason to loose weight is to downsize the engine. Old cars get good fuel economy not because they weigh less, but because their engines are small and consume less fuel.

As far as pulse and glide strategy goes, having a denser (heavier) vehicle can be a benefit for maintaining momentum and extending the glide.

They are designed for a side load. When a bike is at maximum lean and a bump in the road is encountered, the damper is not able to absorb the impact as readily as when the bike is upright. Instead, the swingarm is designed to flex and absorb the sideways force.

This doesn't necessarily mean the suspension can handle the side forces of a heavier trike in corners though. You bring up an important consideration.
