This evening I filled the tank on my 1500. It was last filled just prior to riding a 156 miles with a local group last weekend. We were on back roads and some one laneroads traveling fairly slowly, mostly around 50mph or less with about 35 miles of freeway that varied from a few moments at 95mph to a cruising speed of 70mph. My mileage for this tank was 46.8 mpg. Quite a bit different than the average mileage I got going to and from Montrose. On that run the speeds were often above 70mph and often bucking headwind. The average for the 2600 miles on that trip was around 38mpg. A couple of fill ups achieved less than 34mpg. Just goes to show the effect of high speed running and wind.
Oddly enough I filled the tank on my Silverwing and got about 46mpg. Mostly around town with a bit of fast running on the freeway. Considering that the scooter has half the displacement and just a wee bit over half the weight the Goldwing looks pretty good. I suspect my enjoyment of twisting the throttle hard on the scooter and the reduced efficiency of the CVT is what makes it less efficient over all than the big 'Wing.
