my motorcycle does not coast well at higher speeds, light and not streamlined (tires are pumped up as much as I care to). The saturn glides much farther at higher speeds.

Funny thing is in rc sailplanes they can add weight to make them glide faster but it doesn't have much effect on the glide ratio. Of course it is harder to climb when you are heavier so the extra weight isn't a freebie.
