2018 Honda CBR650F Features and Benefits
The full-fairing sibling of the naked CB650F, the CBR650F touts an unorthodox 650cc displacement size that offers a great mix of midrange torque and low reciprocating mass, earning the model praise as a powerful, nimble midsized four-cylinder sport bike that's ideal for a broad spectrum of users, from weekend canyon carvers to weekday commuters. The competitively priced CBR650F benefits from a number of revisions for the 2018 model year, including enhanced power via updated intake stacks and muffler changes that also deliver an improved sound. The gear ratios have also been revised for improved acceleration feel. The fork is now a Showa Dual Bend Valve unit that has better damping action for more comfort over varying road conditions, and the headlight now has LED bulbs. Rounding out the changes are L-shaped air valves on the wheels to simplify air-pressure adjustment. While the sporty bodywork provides wind-cheating aerodynamics, strategically placed windows offer peekaboo views of the handsome cylinder bank and sculpted exhaust headers.
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.
- Revised intake funnels and updated exhaust enhance power output and provide a raucous exhaust growl.
- 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.
- Revised transmission-gear ratios provide an improved acceleration feel.
- 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.
Chassis / Suspension
- Sport-oriented ergonomics are also comfortable enough for longer rides.
- Low center of gravity (CG), light curb weight, slim cross-section and high-set clip-on handlebars work together to provide lightweight steering feel and responsive handling.
- Full sport bike-style bodywork places the CBR650F squarely in the company of Honda's flagship CBR600RR and CBR1000RR supersport models.
- New Showa Dual Bending Valve fork in large, 41mm diameter with 4.3 inches of travel for a well-controlled yet comfortable ride.
- 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.
- Lightweight cast-aluminum wheels with 120/70ZR-17 tire in front and 180/55ZR-17 rear for full sport bike capabilities.
- Revised Nissin brake calipers and wave-type dual front and single rear rotors (320mm and 240mm, respectively) 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 tail light both have LED bulbs.
- New L-shaped air valves on the wheels allow easier access, simplifying air-pressure adjustment.
