Here's why: 52718.2|306.5|5.379gal.@$2.459/87oct. 56.98mpg (XR650L) Rock&McCarren 7:40am Translation: Odometer (with thousands of miles missing due to broken speedo cables): 52718.2 Miles on trip meter since last fill-up: 306.5 Gallons taken: 5.379gal Miles/gallon = 56.98mpg Yep: 87 octane This includes a 'shortcut' that adds 5 miles of gnarly, fun, steep, rocky offroad to my commute, and about 3 miles of freeway that my regular route doesn't get near. This bike spends some time at WFO or ar highway speeds. Gas mileage has almost never dipped below 50mpg. Yes, I'm one of those AR people that keeps a fuel/maintenance log on all of my vehicles. I have a POS Acrebis 6.0 gas tank. at 56.98mpg * 6 gallons = 341miles range. It has gotten over 65mpg before keeping it under 50mph. I figure that if I want the raw kind of power that pulls my arms off, breaks traction on asphalt through 3rd gear, 0-60 in 2.9 seconds, I'll ride my modified ATK605. So besides the smog removal, the foam air filter and the snorkel removal, my 650L is going to remain 'stock'.
