Meets current EPA standards. California version meets current CARB standards and may differ slightly due to emissions equipment.

Honda 399cc version of its 2013 500-series motorcycles for the Japanese market. The Honda CBR400R, CB400F and 400X will be offered in Japan instead of their respective 500 versions, as they are a better fit to the country’s tiered licensing system than the CBR500R, CB500F and CB500X.

Like the larger engine, the new powerplant is a liquid-cooled DOHC parallel Twin engine. The smaller engine has the same 67mm bore as the 500 engine, but at 56.6mm, it has a smaller stroke than the 500 engine’s 66.8mm.
