Best MPG petrol motorcycle out there?

[Stuart]

I keep hearing about this Honda NC700 from other bikers. I like to think they are coming around to our way of thinking, slowly Sounds like a nice, torquey ride anyway.

We've got cars that will do that lol
The Enfields are very good although you won't get the same performance and the LML(stella in the US) 4 stroke scooter is said to be capable of 120mpg although that's at commuter speeds.
It's always been the case with older bikes if you fitted a single carb conversion SU or Amal you got considerably more mpg and a much more flexible bike for not much loss in performance.
I've always wondered what some of the Japanese 4 cyl bikes would achieve if the 4 carbs were removed and a single carb/ manifold fitted??
I know these days that emissions/laws etc. make a lot of this on modern bikes impossible.
Hopefully if the Japanese start concentrating on MPG we might see some useful bikes coming out and I haven't mentioned diesel

200+mpg with a fairing? http://www.velomobiel.nl/allert/

Very nicely constructed and it proves the theory

My little 2006 Honda Rebel averages mid-60mpg US and will still do 65-75mph on the highway. Got 80mpg running lean with straight pipe exhaust before rejetting the carb.
Main complaint is the 2 gallon fuel tank requiring refill every 120 miles making long trips impractical. It does need premium gas when riding in the mountains (6000-11,000ft) to prevent knocking.
