On the 250 ninja, 70 mpg was the highest tank average I got, although I never really hyper miled it. It was just when I felt like riding lazily.
On the 600 Ninja, 54 mpg is the best tank average I've got, with it regularly being closer to 45. The 600 does not like to cold start at ALL. So I have to run the choke some even on the warmest of days. Once its warmed up though.. wow.
