How much MPG can i expect from these bikes?

[skimsurfer]

a 2005 yamaha FZ6
and a 99 gsxr 750
what can be done to either to increase mpgs?

Honest answer is 40-50 mpg depending how they are ridden, to increase mpgs drive slower or less distance.

40 MPG estimated EPA, which means ridden responsibly with no fast starts, and driving very conservatively. Ridden hard that wil drop significantly.

I couldn't find anything onthe MPG for the GSX-R which is probably not a good thing. If you are looking to get better mileage, these two are not it.
