2015 Honda CB300F, MSRP $3,999 excludes $310 destination- 2015 CB500F motorcycle - Less Is More: the New Honda CB300F is Here. The new 2015 Honda CB300F—you get all the great CBR300R features, but in a bike that offers the pure, clean look some riders prefer—and once you see a CB300F, you may prefer it yourself. An added plus: The CB300F is a little bit lighter, and you sit up a little straighter. You’re a little more involved in your riding world. It’s an especially good choice for the urban rider. The two share the same great engine—bigger and more powerful than the CBR250R, it offers a wider powerband and more power, great traits for a bike in this category. Like the CBR300R, thanks to it’s single-cylinder engine design, the CB300F is narrow, light, and fun. And the fuel-injected engine also offers excellent fuel economy.
