Orion RXB 190L
The Orion RXB 190L is about as close as you can get to what you’re looking for, but again, it’s the 5 speed ZS190 engine, not a 6 speed. It’s street legal and powerful (@ 16HP stock; some say 18) and only 178lbs, but again, it’s street legal pit bike with a dirt bike seat and essentially what is a racing engine. ZS190 engines are known to be higher maintenance and finicky (i.e., starter chains breaking).

I can't help but think that if you consider how much work is actually done for the amount of fuel consumed, they are all incredibly inefficient. Is that a fair statement?

If you compare it to a roketa mc 05 127, or a Grom, both getting well over 100mpg, any bike will look poor in comparison. The first bike being geared very aggressively for higher mpg/lower rpm per mph. The Vader 150 is quite poor in it's gas mileage. Granted, I ride it at 6k rpm most of the time, and get a solid 60mpg out of it, while it gets closer to 80mpg when keeping it between 3 and 5k rpm. This engine should be able to do 100mpg easily at 40-45mph (doing ~ 4k rpm. A lot of the China bikes have lower performance when they're: a- Air cooled, and, b- not fuel injected. Mainly because they'll run a pretty low compression ratio. If there was only an easy way to increase compression ratio on pushrod engines... Especially people in colder regions will benefit from this (higher gas mileage, same or better performance). |

Seems like another contender (5spd) is the magician 250.

there are reports of 100cc bikes in India getting 100kmpl/235mpg.
But that's India. I can't say the models off the top of my head but that 100cc segment is cutthroat over there... You would not be going particularity fast by western standards. |

A 4 stroke carbureted bike, ideally reaches up to 120, and that's with heavy overgearing. Fuel injected bikes can reach up to 150mpg, because they can lean out the mixture so much when power isn't needed and load is low. So, reaching 200+mpg, may be possible on a mountain trail downhill. |
