The liquid-cooled 649 cc four-cylinder engine uses a compact internal architecture with cylinders canted forward 30 degrees for a lower centre of gravity and an impressive power-to-weight ratio.

Balanced powertrainTuned for increased torque and effortless performance in low and mid-range power, the versatile 649 cc DOHC features direct cam actuation and 11.6:1 compression to increase peak power delivery at a thrilling 11,000 RPM. |
Even more powerThe pistons and valve timing boost power even higher, giving the CB650R its sportier character. |
HSTC torque controlThe Honda Selectable Torque Control System (HSTC) controls torque output by detecting differences in the slip ratio between front and rear wheels. When the rear tire loses traction on a slippery surface, HSTC instantly kicks in and suppresses torque by controlling fuel injection to inhibit rear tire slip. This system is user adjustable and can be turned off |

Quality engineeringAsymmetric piston skirts, ferrous spines on the cylinder sleeves and a silent SV cam chain using a Vanadium coating on its pins ensure reduced friction, minimal oil consumption, and improved heat transfer. |
Quick responseThe PGM-FI fuel injection system operates with information from four separate throttle body sensors for crisp and accurate throttle response. |
Optimal fuel economySpecific fuel-injection mapping and ignition timing work together to optimize fuel economy and deliver impressive range from the generous 15.4 L fuel tank. |
Streetfighter designThe exposed side-swept downpipes pay homage to the vintage CB400, while also offering a modern streetfighter design twist. The exhaust now sports a larger bore tail pipe angled upwards to increase airflow while producing an emotive sound. |

FrameThe CB650R’s twin-spar steel frame is engineered to be light, strong and to improve mass centralization, providing the basis for the bikes sporty handling and high level of rider feedback. |
SuspensionShowa 41mm SFF-BP USD forks are a major upgrade over the previous generation; a pressure separation damper in one fork tube and spring mechanism in the other deliver high damping performance and lighter weight. Together with the use of a larger sized piston the result is increased feel, bump absorption and control. Adjustable for 7-stage spring preload, the single-tube monoshock operates directly on the curvaceous gravity die-cast aluminium swingarm. |

Digital displayThe backlit digital display tells you everything you need to know about your ride, with a speedometer, tachometer, odometer, gear indicator, fuel gauge, clock, warning lights, plus all trip details including average speed, fuel consumption rate and elapsed time. For 2021 readability has been improved with a change of LED angle and font size |
Safe and soundA compact wave-design ignition key offers increased security and reduced chance of breakage. |
