Never thought of looking there, thanks. While there were no studies I could find, significant data was posted by several suggesting that mpg peaks at around 80 to 85 degrees. Exactly what I was thinking with very limited data. It appears that the increase is linear from about 40 degrees to 85 degrees, with a considerably steeper line below 40. Very interesting.
For the first time in 6 months I checked my tire pressures (bad owner). To my embarrassment, they were 8 psi low. That makes me think tire pressure on a motorcycle is a fairly trivial component of efficiency as my last two tanks were 79/78 mph, a personal best per the title. I certainly notice low pressures in car efficiency.
Anyone anecdotally documented lower mpg on under inflated tires?
On my OEM Dunlops, I could notice lowered handling performance with just 4 psi under inflated. I'm only on my second set of tires, but could not tell the difference with another brand. That's a bit concerning on a couple levels.
8psi low isn't really that low: remember the pressures listed is for max pressure at max weight (460lbs-weight of rider, pinion, and any luggage).
