I think my best has been about 33 mpg for one tank of gas. It improved slightly after (over?) inflating the tires (42/42). I never lug the motor and rarely over rev. 90+mph (indicated) is not uncommon, but typically 80 ish on the freeway (5th gear) and 50-55ish (3rd/4th gear mostly) on local roads. Acceleration is "moderate" I suppose. My other rides are generally a lot lighter and a lot more powerful than the ST and while I don't try to compete with the same sensations, I imagine I might ride a little faster than average, especially around turns, of which there are not many along my commute. I will pay more attention to what gear I'm in and try your suggestion as well. Thank you.
