I'd say it's possible. At least I know about a guy who rode a BMW G650GS single on a fuel economy run, at 103mpg. The bike wasn't streamlined, the rider was He brought a pillow and used that to keep tucking during the whole run. With streamlining it should be easier to surpass 100mpg. Without it I haven't ever succeeded, even with P&G (which Craig hates but I love indeed...)

But I have several 90mpg+ tanks (all "real life"), so it shouldn't be too far.
