In terms of performance, the 300‘s bigger motor yields noticeably stronger low-end and midrange grunt. Drop into first, slip the clutch at idle, and you’re on your way. I found myself short-shifting to fifth or even sixth gear while puttering around town, mainly because the little thumper has enough power on tap to accelerate from as low as 3,000 rpm. Honda says the 37cc bump—accomplished by way of an 8mm increase in stroke—boosts peak output by 17 percent. The last CBR250R we ran on the dyno made 22.3 hp, so it’s likely that this new bike will make somewhere in the neighborhood of 26 hp. That’s still quite a bit down on the 33 hp the twin-cylinder Ninja 300 puts to the rear wheel, but plenty for urban riding, carving canyons, and the occasional freeway run. Honda says that revised fuel mapping allows the 300 to squeeze 71 miles out of every gallon of regular unleaded. And while that seems like a big number, it’s actually 6 mpg down from the claim made for the 250.
