100% disclosure....I ride like a total asshole most of the time. I always accelerate like I'm trying to win the hole shot at every light. My setup is Big Air Kit open air cleaner, VH Comp Exhaust, Cobra FI2000. I'm one of the first people to have the KOSO, and my shit is locked in. My bike also has to move more mass than Joko. He's fully loaded at 160lbs, that was my fighting weight in 1993. I'm 5'9" and about 215lbs (most of it in my testes), plus I have the fairing, saddlebags, and I live in Delaware, right at sea level, and it's flatter than most of my dad jokes.
There was ONE night I rode home in a storm for the entire 100 mile trip. I went the speed limit the entire way, like a little bitch. My fuel light came on at 128 miles. That's 53 MPG. So I'm sure if I rode my bike like a tool and went the speed limit everywhere, everyday, I would spend less on gas. Regardless I'm going to have to fill up before I go to work AND on my way home. And it's like 5 bucks to fill up so who cares?
