I just recently purchased the 650 Exec and took it on the Interstate for the first "long" trip. The round trip was approximately 320 miles. The tank was filled for the start of the trip and I would say around the 110 mile point the low level fuel light began flashing (the gas icon and the one remaining bar). My average speed was 80 mph. No choice but to fill up and continue. On the return trip same thing...another fillup. The computer was averaging betwee. 37-39 mpg. All in all with two gas stops I paid about just under $40 for fuel that day with current prices at $4.20/gallon. I was almost shocked how much fuel it consumed albeit perhaps my speed was higher than a usual crusing around town speed. Apart from the beautiful ride and comfortable as the ride was is this the BEST range this scoot has? Interestingly enough I began the journey with the POWER mode selected and after the first stop selected it off as I thought that was going through excess fuel. But it made no difference once it was back in D. I heard this bike would be just as (or more) comfortable than bigger cruisers out there if one decded to tour across the countrywith it. If I was to do that I would be stopping at least every hour or 110 mile mark to fillup....not fun. Any comments about the range or what I can do to improve this? Thanks.
