As a new Spyder owner I have put about 900 miles so far on my 3 week old 2021 RT. I always have it in ECO mode, and have tried to shift when the orange arrow lights up (I assume older model years had a green arrow from the comments here). Mostly I am finding that I get about 33 mpg. On a group ride, riding solo, and at the very modest pace the group was traveling (mostly Honda Goldwing trikes), I got 38 mpg. But the rest of my riding, mostly two up but not aggressive or with much at speeds over 70, the 32 or 33 mpg seems pretty consistent. I didn't buy the Spyder for its gas efficiency, but I was a bit surprised at the low mpg. The Spyder weighs about the same as the Goldwing that I just traded in, but the Goldwing's engine was significantly larger (1832cc vs 1330). Yet the Goldwing gave me 37 to 39 mpg regardless of how I rode it, and regardless of whether I was riding solo or two up. Still, having the ability to easily go 200 miles between fill ups is more than acceptable to me.
