not exactly sure on my 96 vmax 600 but i find myself having ridden about 40 miles when im at half a tank according to the gauge. this puts me at about 80 miles to a tank and 10 miles to the gallon give or take a mile or 2. its not great but i love the sled and am willing to keep fillin it up
The triples get much better gas mileage. The group I ride with has a 99 500 phazer-01 V-max 600-2000 500 kitty-02 550 kitty. My 700 beats the snot out of all of them by a big margine. Except the 550 kitty. We are very close. Not at first though, he had all kinds of problems with it the first year. That thing ate the gas and oil until he took it back for a good going over. I had a 97 500 xtc and that only got 11 mpg. MM.
i got the respectfully labeled TANKER. it's a '95 380(my 500 got totaled, so i had to ride it), those get like 160 miles on one tank. the other riders looked down and could see the tubing, i had a half tank!
i must say, i think those yamaha triples make gas! lol. its just from they're small carbs, their carbs are excellent for low end and mid range but at top end a bigger carb dominates. i never really have figured out the milage on my sled yet, but if you drive it decent it does pretty good, but damn, i love that throttle.
