Honda's iconic CB moniker evokes a proud legacy of middleweight machines that boast user-friendly four-cylinder engines mated to nimble, confidence-inspiring chassis. That's also an accurate description of the CB650R, which features a Showa Separate Function Big Piston fork, excellent emissions performance, aesthetics and comfortable ergonomics. Showcasing Honda's Neo Sports Café design theme through its smooth lines and compact packaging, the CB650R is a popular and enjoyable naked bike that builds on the CB history of catering to diverse riding experiences, from daily commutes to exhilarating outings on tight, twisting backroads.

STYLING
Tightly wrapped and aggressive, the CB650R's Neo Sports Café style features the signature compact "trapezoid" proportion of short, stubby tail and short-overhang headlight. The long fuel tank is a key motif of the family design; its smooth lines accentuate the solidity of real metal surfaces and crown the engineering of the four-cylinder powerplant. It also houses the ignition.

The handlebar is set forward for good ergonomics, and the LCD dash has good visibility. The round headlight is based on that of the CB1000R. It's LED, as is the rest of the lighting. Sharp LCD instruments also use the CB1000R as a baseline and include Shift Up, Gear Position and a Peak Hold indicator, which brings attention to the peak revs and offers a dynamic experience for the rider.

A 21.9 inch tapered handlebar is shaped and positioned to offer a sporty yet comfortable riding position, as is the foot-peg position. Seat height is 31.9 inches.

CHASSIS / SUSPENSION
The CB650R's steel-diamond frame uses pressed swingarm pivot plates for weight savings twin elliptical spars with a rigidity balance specifically tuned (stiffer around the headstock and more flexible in the spar sections) to deliver balanced handling characteristics with high levels of rider feedback. Curb weight (measured with all required fluids) is 447 pounds. Much is owed to weight-saving measures in the frame, fuel tank and super-sport-style footpegs. Handling is further aided by an ideal centralization of mass.

Front suspension comprises an inverted 41 mm Showa Separate Function Big Piston fork – high-quality suspension that improves the bike's handling. The fork is held by a forged-aluminum bottom triple clamp. Adjustable for seven-stage spring preload, the single-tube shock operates directly on the curvaceous, gravity die-cast aluminum swingarm.

Four-piston radial-mount front brake calipers work on 310 mm floating rotors and are paired with a single-piston rear caliper and 240 mm rotor. Two-channel ABS is standard. The cast aluminum wheels are designed with five Y-shaped spokes, reducing weight by front and rear, which also improves handling by reducing inertia and unsprung mass.

ENGINE / DRIVETRAIN
Honda's development engineers wanted to create the purest, most enjoyable midsized four-cylinder performance possible for the CB650R rider, so the 649 cc, DOHC 16-valve engine has been tuned to deliver good power above 10,000 rpm. Peak power arrives at 12,000 rpm, with peak torque delivered at 8,500. The net result is a motor that spins well at high rpm, with a smooth, linear torque delivery that builds strongly as revs rise, and sounds great in the process.

Direct cam actuation makes for a compact cylinder head; compression ratio is 11.6:1. The valve train is reinforced and iridium spark plugs employed.

Asymmetric piston skirts minimize bore contact, reducing friction. Ferrous spines on the outer surface of the cylinder sleeves reduce oil consumption (and friction) with improved heat transfer, and a silent SV cam chain reduces frictional losses by using a Vanadium coating on its pins. Internal water channeling from the cylinder head to the cylinders does away with most of the exterior hoses.

Twin air ducts on either side of the fuel tank feed a large volume of air, raising atmospheric pressure in the airbox. They also produce a throaty intake roar. The exhaust features a large, 1.5 inch-bore tail pipe inside the muffler to flow more gas and, with its exit pipe angled upward, to emit an emotional howl.

The engine uses a compact internal architecture, stacked six-speed gearbox and starter layout with the cylinders canted forward 30°. An assist/slipper clutch eases upshifts while managing rear-wheel lock up under rapid downshifts, while Honda Selectable Torque Control (HSTC) manages rear-wheel traction; it can be turned off should the rider choose.

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