188mpg Yamaha retrobike
I know what I want for xmas... yet again, something I won't get. 
Yamaha shows retro lightweight 125cc motorcycle that gets 220 mpg
With 20-24" (?) OD tires it's pretty small though.

I bet it is even fuel injected, other then that part it would be possible to build something like that your self, use rims for down hill mouton bike racing, same with the suspension fork and brakes.
It's a really cute bike and I bet it would sell well.

220 mpg is probably ONLY 170 mpg on the U.S. EPA cycle.

I agree 
Looks too fragile for our bad roads (and the trail to our house), though. But I might be wrong. |

Looking at it's frame and comparing it to the frame that my Honda CB125 has, that Yamaha almost looks tougher, of course the paint job doesn't make it look tough. |

It's not the frame, I worry about the rims, which are as thin as bicycle wheels. They have large diameter though, which gives some protection against potholes.

They look like 24" bicycle tires to me, but I have not been able to locate any information on them. I'd think wheels and tires developed for mountain bikes would be strong enough at such a low vehicle + rider weight, especially with plush suspension on both ends to protect them from severe jolts. But I do wonder about what the speed limitations of standard bicycle tires are.

In down hill off road racing it seems like 40 to 50mph could be seen on a bicycle while hitting bumps that are larger then you could ever see on the road, you aren't going to find tires that take that kind of abuse at Wal-mart but there are some really impressive street tires as well that fit mouton bike rims if you look around.
