2018 Honda CB650F Features and Benefits

  • CB650F
  • CB650F ABS

Honda's newest middleweight naked bike is powered by a compact 649cc inline four-cylinder engine that provides a satisfying rush of power and torque while emitting a throaty growl through beautiful side-swept exhaust headers (a Honda signature) and a single, organically shaped, under-swingarm muffler. With minimal bodywork, the view of the handsome engine and twin-spar frame is unobstructed. Suspension comprises a Showa Dual Bending Valve fork and adjustable shock, and both the headlight and taillight feature LED bulbs. All three brake rotors are wave-style, the dual 320mm front discs being squeezed by Nissin calipers. Longer rides are made comfortable by the sporty-yet-natural riding position and a rubber-mounted handlebar.

Engine / Drivetrain

  • 649cc liquid-cooled inline four-cylinder engine features a muscular torque spread through the low- to midrange portions of the powerband, especially below 4000 rpm.
  • Tuned especially for strong acceleration from a standing start and strong midrange roll-on throttle response for real-world street-riding performance.
  • Liquid-cooled inline four-cylinder engine features Honda's Programmed Fuel Injection (PGM-FI) system.
  • Dual overhead camshafts actuate four valves per cylinder. This layout allows a high degree of freedom in cylinder head design for optimum performance.
  • The camshafts are driven by a silent-type cam chain for reduced engine friction, and the surfaces of the cam-chain pins are treated with vanadium for lower friction and increased toughness.
  • The piston pins and connecting rods are treated with a special friction-reducing protective coating for greater durability and efficiency.
  • Cylinders are inclined at a 30-degree angle to help lower the center of gravity (CG) for more agile handling.
  • Sweeping right-side four-into-one exhaust system is both stylish and functional, and muffler emits a raucous growl.

Chassis / Suspension

  • Upright riding position and rubber-mounted handlebar for a comfortable ride.
  • Low center of gravity (CG), light curb weight, and slim cross-section work together to provide lightweight steering feel and responsive handling.
  • Street fighter styling places the CB650F squarely in the company of Honda's CB1000R and CB500F naked models.
  • Minimalist bodywork makes for a tough, street-fighter image and allows a full view of the engine and exhaust.
  • The frame incorporates elliptically shaped twin 64mm x 30mm steel spars for tuned flex to deliver excellent sport riding characteristics.
  • The engine is incorporated as a stressed member of the frame, an efficient layout for enhanced handling.
  • Single-shock rear suspension is actuated directly by the strong yet lightweight aluminum swingarm for 5.0 inches of rear-wheel travel.
  • Shock spring preload is adjustable in seven steps to accommodate variations in load and riding conditions.
  • Large, 41mm Showa Dual Bending Valve fork with 4.3 inches of travel for a well-controlled yet comfortable ride.
  • Lightweight cast-aluminum wheels with 120/70ZR-17 tire in front and 180/55ZR-17 rear.
  • Wave-type dual front 320mm disc brakes and 240mm rear give strong stopping power and lend a stylish touch while also saving unsprung weight.
  • Honda's ABS system is available for more confident stopping in challenging conditions.
  • LCD multi-function digital meter package includes speedometer, tachometer, odometer/A&B trip meters, fuel gauge and clock. Meter can also display average and instantaneous fuel consumption.
  • Under-seat utility area adds modest but convenient storage space.
  • Headlight and taillight both have LED bulbs.
  • L-shaped air valves on the wheels allow easier access, simplifying air-pressure adjustment.

Transferable one-year, unlimited-mileage limited warranty; extended coverage available with a Honda Protection Plan.

  • Meets current EPA standards.
  • Models sold in California meet current CARB standards and may differ slightly due to emissions equipment.
