When Honda introduced the single cylinder CBR250R a few years ago, we found it a competent, fun bike that was easy to ride and had just enough power for freeway commuting here in Southern California.
For 2015, the big news is that Honda has increased engine displacement to 286 cc courtesy of an 8 mm increase in stroke. Honda claims that this provides a 17% increase in horsepower compared to the CBR250R.
The other changes are not as dramatic. They include a redesigned fairing with dual headlights, new, higher volume exhaust system, new, narrower seat (providing an easier reach to the ground), and even a small detail like the stalks on the mirrors (which are shorter this year).
The engine has several new parts, we are told. Making it all work together required a remapping of the fuel injection system.
Ergonomics are essentially unchanged, and continue to provide a comfortable, semi-upright seating position to help riders enjoy the considerable range (a claimed 71 mpg) from the 3.4 gallon fuel tank. Claimed curb weight (all fluids, including a full tank of gas) is unchanged from last year at 357 pounds (364 for the ABS version).
