2010 Kawasaki KLX250SF, SUPERMOTO STYLE!!! - Sticky street rubber meets lightweight DualSport big fun can t be far behind. Type big fun in a small package into your internet search and it might take you straight to the Kawasaki KLX250SF supermoto. Based on Kawasaki s critically acclaimed KLX250S dual sport on / off-road bike, the SF dials up maximum on-road fun with sticky street radials mounted on 17-inch wheels, a shorter seat height, a bit less suspension travel and a big front brake. It s just a 250, but its light weight of just 302 pounds means the KLX250SF packs the sort of performance you d expect from something bigger and more expensive. Few motorcycles of any size or price are capable of out-cornering it.
