Honda CB300R

The Honda CB300R is a CB series 286 cc (17.5 cu in) single-cylinder standard/naked bike made by Honda since 2017. Graceful, nimble, and a blast to ride, the CB300R is full of innovative engineering to make riding fun. Its single-cylinder engine makes it light and narrow, and the new chassis is the basis of its sure-footed handling. Agility comes from the steering geometry that measures in with a 24.7-degree rake and 3.7 inches of trail over a 53.3-inch wheelbase.

About the Honda CB300R

The Honda CB300R is making its debut in a highly competitive market segment. Combining contemporary styling with light weight, a low seat, and appealing power, the CB300R is as compelling to beginners as it is for more experienced riders.

Honda expanded its Neo-Sports Café lineup with the new-in-2019 CB300R that brings more of the same café-tastic vibe as with the CB1000R, an entry level-size package. This naked little pocket crotch-rocket looks pull in younger riders with a user-friendly, 286 cc powerplant and lightweight design.

Honda went with a tubular-steel frame that uses pressed-steel components to finish the assembly on the CB300R, but deliberately kept the stock thin in order to keep weight down. It seems to have worked out well since the CB300R weighs in at only 317 pounds, wet.

Cast aluminum wheels do their part to help the suspension out as well, and while the 41 mm stems come with 5.1 inches of travel up front and monoshock gives up 4.2 out back, the system is plain vanilla as far as adjustments go. Spring preload out back, that’s all you get.

Agility comes from the steering geometry that measures in with a 24.7-degree rake and 3.7 inches of trail over a 53.3-inch wheelbase. As light as it is, the 300 doesn’t really rate dual front brakes so the single anchor is plenty to keep it under control. Last year, you could take or leave ABS, but for 2020, ABS is the only game in town.
