How much difference is there in highway fuel economy between 250cc motorcycles and 400-750cc models?

Question

Also, would the 250cc bikes be a lot more susceptible to cross-winds and other conditions, or would they be roughly the same?

Thanks!

Answer 1

motorcycles were not built for gas mileage, they were built for fun

Answer 2

fuel economy depends on the rider. if you put a 250 pound person on a 250cc bike it will be bad. rule of thumb is 2cc per pound. yes wind sheer is a problem if the bike is too big for you.

Answer 3

I have an 07 Kawasaki Vulcan 900 and get usually 45-47 on the highway.

Answer 4

The UM bikes must get better mileage

My 650 gets 56-59 mpg

the 250 guys on our forum say 70-75 mpg
