He ran the bullet bikes laying down prone, no luggage, and much slower in 1983. 470 mpgUS but useless for real world transportation.

Ohhhh, I thought there was something recent. One can still run the engine of their choice.

As long as you don't get dropped. You must be capable of running with 70 mph highway traffic into a 30 mph headwind.

That was exactly my point, you can't use a 50 cc bike in the Vetter challenge because the speed requirement is reasonably too high.
On the other hand, I believe a 50 cc bike would be a winner on a 45 mph MPG contest.

I guess what I meant to say was that a top flight Vetter competitor that was capable of doing 140 mpgUS at 70 mph could also make 200 mpg at 45 mph.

I guess I understood what you were saying and I disagree.

Lets take a very good exemple :
our finest ecomodder on two wheel is the Velomobiel, the only subject topped in the motorcycle section.
The guy did 214 mpg tops, cruising around gently let's say like in a 45mph challenge.

Could he do well in a Vetter challenge ?
I don't think so.
Or say I would like to be proven wrong.

That bike can't complete the Vetter challenge. It is too slow.

[renault_megane_dci]

YES !
It is too slow but it is also the best MPG wise we have.

Do you think say a 250 or even 300 Ninja could better it MPG wise at any speed ?

[sendler]

Not quite. 200 mpg is the holy grail. But the Hayes Diesel is close. He is consistently over 130 mpgUS in Vetter challenges with slightly less than optimal aerodynamics. I wonder what his best could be at a slower speed?
