Yesterday was our first opportunity to sample the mono-cylinder CBR250R on U.S. soil. After flogging it on the interstate, around town, and along some of the best curvy roads in the country – in the canyons above Malibu, Calif. – we came away reasonably impressed, although not surprised.Living up to the predictions of its spec sheet recently analyzed in our tech review, the fuel-injected bike starts and warms seamlessly with no stuttering when pulling away cold from a stop.
