2011 New Honda CBR250R 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.
The new, fuel-injected CBR250R offers everything you want in a first-time bike: Light weight. A powerband that’s immensely user-friendly. Excellent fuel economy. Unmatched reliability. And a fun factor that’s off the chart.
The new CBR250R is powered by an extremely efficient 249cc liquid-cooled single cylinder engine that features a sophisticated four-valve DOHC cylinder head, engine counter balancer, and fuel injection—this dependable and lightweight machine delivers nimble handling, a broad spread of easily accessible power and low operating costs all in one. The motorcycle weights only 359 lbs.
Since the new CBR250R is a Honda, it’s full of features few other bikes in its class can match. And it offers a build quality that means you’ve got dependable cross-town or cross-country transportation.
The DOHC liquid-cooled single-cylinder 249cc engine of the 2011 CBR250R is an all-new design that was erected specifically for this bike – as was the chassis. The power plant plays host to a counterbalancer for reduced vibrations, roller bearing-equipped rocker arms that activate the valves and a spiny-sleeve cylinder that will keep the engine’s temperatures down. An interesting side note is the fact that the rocker arm design of the single-cylinder engine allows for valve shim adjustment without removing the cams. And speaking of valve adjustments, Honda says valve adjustment intervals are right at 16,000 miles – which is similar to the intervals of the 250’s larger CBR relatives.
