after 3 fill-ups, I calculated 43 mpg on my 2005 gsxr 750.
cruising range of around 145 miles before the low fuel light engages.
this is from normal commute to work and back.
i was expecting to see it around 35 mpg.
still too damn cold for me to try a commute. mine is 53 miles though and through some pretty twisty roads. I am still too newbie on my bike to try to make it at 6am when it is real foggy on the river. Can't wait til spring though.
