I think most of the high mileage posts are at least pre 05 bikes. I have noticed that many of the discussions over acceleration, power, MPG etc. don't take into account the changes that have occurred over almost 10 years of production. A 99 and an 08 have a lot of differences.
Of course if lower per mile expenses are a goal then buying an LT is probably not a good choice. I'm sure over the next few years I will spend a lot more on service, parts and tires than I will for some extra gallons of premium gas. My tank lasts longer than my butt and my bladder anyway.
Assume you are responding to me:
I consistently get in the very high 40s and that includes some red line run ups in the lower gears - in other words I do not baby my ride at all. (Come join me one Saturday morning when I am in the chase with my friends on their 1200 GSA's, 1200 RT's and, on occasion, a dam Ducati 1098S. The ole fat girl can hang in there pretty good - still in the mid to upper 40s). I think one of the reason for my economy is that my bike was broken-in hard and the rings were seated properly early on.
Cruising in good weather with the shield down (where it usually stays) and the wings in - 52 to 55 MPG is well within reach. 325 mile on a tank is no problem at all as long as I stay below 85 for extended periods ( 81 works out about perfect for my ride - 4,000 RPM, engine smooth, airflow smooth) - and that includes 2 up with luggage.
An 08 may have more horse power (which should make it more efficient?), but the 5th gear drive ratio is lower than my bike so my cruise should be more efficient.
I did not purchase my bike for it's economy, but it sure is remarkably good for a bike it's size. In fact, it is not unusual to ride with some Harley / GL riders and have them ask, "how much dam fuel does that thing hold?". Riding their ride and purchasing fuel at every other stop seems to get their attention.
