Such changes usually Novocaine up handling, but that's not what happened here. Thanks to different tires—the X model rolls on Pirelli Scorpions—and a taller, wider (by 3.25 in.) handlebar, the CB-X flicks into corners with an eagerness that makes it feel lighter than the 425 pounds (wet) our scales show. Its steering is neutral, if not exactly light, with little of the CBR500R's tendency to become heavy feeling as you lean farther. Because the CB-X shares frame, suspension rates, crazy-squishy footpegs, and low peg carriers, it has functionally about the same cornering clearance as the CBR500R, which is to say not quite enough. The additional fork travel helps incrementally—an increment you'll measure with a micrometer not a yardstick—but the X's chassis is plainly more eager for fun than its softly calibrated suspension allows.
