It's gotten to the point where I feel like I'm being greedy driving my little '09 eco hatchback instead of my motorcycle and how much weight a subsequent fuel is being carried around and burnt to move me through the town on my way to work. 2800lbs vs 366lbs
What is mind blowing to me is how little weight impacts the fuel efficiency in my situation. I get ~58 MPG on my 385lb bike and ~55-60 MPG in my 3,500lb Prius prime. Obviously the regen helps, but still it is crazy how efficient the Prius is.
This is more a reflection of your motorcycle engine favoring power, low weight, low emissions, and low cost of production over efficiency. There are people with DIY efforts that can get something like a 125cc 9 horsepower Honda engine to get over 200MPG at around 230 pounds and 55 MPH
