Re: CleanMPG reviews the 2008 Yamaha XT250
As the owner of many small-displacement bikes over the last 20 years I've always known about the 'huge' MPG these little 250s are capable of, even with a 200+ lb rider like myself.
My current 'trail bike', an '05 Kawasaki KLR-250 can bring back fantastic MPG when used in city, or highway only. I use it primarly for scooting about desert trails, many times at lower speeds, and often at higher RPMs when climbing hills/mountain trails, and it still returns 60-65MPG with what I would consider to be horrible FE conditions.
All that said, even with 20+ years of motorcycle experience with everything from dirt bikes, to light-displacement enduros, to sport bikes, to larger touring bikes, I find myself shying away from riding my bikes on the highway. Too many folks just drive too crazy and just don't 'see' you on the bike, or just don't care (probably a combination of both). I'd like my boys to have me around for a bit, so I pretty much steer clear of the freeway nowadays.
