About a year ago I did an experiment, running my uly down the highway in 5th gear, returning in 4th, and comparing the gas mileage both ways. I was surprised and pleased to learn that it gets better mileage in 4th, a finding that has been confirmed by other people. It would be an even more interesting experiment with the 1125. You've got your choice of 3rd, 4th, 5th, & 6th for highway cruising. If I actually owned an 1125, I'd do this experiment myself. Since I don't, I'm posting this and hoping someone else finds the idea interesting. I'd love to know what the answer is. | ||

Did you have a headwind in fifth and a tailwind coming back...? I say this only partly in jest, as I face this most of the time in my local rides, and I can see it reflected in the instantaneous mileages I get on the 11's panel display. To the point of your question, I have found that fifth and sixth return very close to the same mpg readings between 60 and 70 mph. Above 70, sixth gear does better - rpm at 70 is about 4500.

Seems like I read somewhere on BadWeb that EPA tuning is to meet emissions for this bike at about 4400-4600 rpm which I believe would be the best mileage due to leanest fueling condition. Naturally the highest cruising speed below where wind resistance becomes a factor should render the highest mileage. This was my experience also 4500 rpm in 4th or 5th. Easy on the engine also. If I remember the instant mileage readout was near 40 mpg. | ||

Ditto. According to the computer, this bike likes 4K or so. | ||

If I remember correctly, I get about 38 mpg when I'm cruising at about 4500 RPMs. I might have gotten 39 mpg once. I commute 80 miles per day, about 80 miles and I usually ride it 5500-6000 RPMs. This cuts my mpg down to about 35. I'm about to make a trip out to Prescott, AZ, from Riverside, CA, so I'm interested to see what kind of mileage I'll get. From experience it seems that the longer the trip is with a consistent speed the more mpg I get. My bike is pretty broke in: 9k + on the ODO. | ||

Did you have a headwind in fifth and a tailwind coming back...? I say this only partly in jest I don't know. I only did the experiment once, to have more confidence in the numbers, I'd need to repeat it a few more times. But others tried and some also get better mileage in 4th and some don't. It isn't clear what the difference is. Our current hypothesis is heavier riders do better in 4th. | ||

Pay close attention to tire pressure. I dropped from 42 to 39 psi and lost 7 mpg over a tank. I'll keep my tires tight unless i hit the hills. Shane - did you say you got 9k miles on your original rear tire? What pressure are you running? Zack | ||

wHAT IS THE max pressure per the sidewall? | ||

Zach, I have a correction to make. I was just looking at the work order for my bike when I brought it in to get the back tire replaced. It only had 8,743 miles on the ODO. I have 34 psi in the front and 36 psi in the rear. I've just maintained what the manual says to keep it at. | ||

Wow, I took a bunch of heat for my tire life - I got 6100 or so. The first 3000 were in 15˚ - 45˚. Avg fuel has been constant at 37mpg. Congrats! Z |
