I wouldn't be happy with 50mpg city. Though being that I live in Maine, "city" is a lot different here than elsewhere. Even in the "city" here you are still normally averaging 35-40mph with very little stop and go.I would be more than happy with that!
I'm getting 75+ mpg on my CTX700N, so I get less than 90mpg on my Grom, I'll be disappointed.I would expect more; my CTX 700N is suppossed to get an average of 62 or 64....and that has over 500cc more but has 2 cylinders instead of one....??? Plus, as you know "Your mileage may vary ba......."
It could be, you never know. With an older carb'd 80 we ran for something like 4 hours without using a full gallon of gas lapping on a track. I doubt we did that distance but we rode the snot out of them.130 mpg must be imperial gallons, not US. Look up Fuelly for motorcycles. The Honda elite gets 88 mpg av. The Wave is about the same, and the PCX125 which shuts down at traffic lights reports 91 mpg as the most common av. mileage. 130 mpg is not realistic.
