Honda's CB650R brings modern performance and timeless style together in one accessible, enjoyable package. Offering the thrill of a sport bike without sacrificing everyday comfort, it blends the precision of a naked machine with Honda's signature refinement. The inline-four powerplant and advanced chassis deliver a uniquely balanced riding experience—spirited on winding roads yet composed in city traffic. With its minimalist design and innovative Honda E-Clutch technology, the CB650R proves that performance can be both practical and emotional.
HISTORY
First offered in the U.S. for the 2018 model year as the CB650F, the model served as the naked counterpart to the full-fairing CBR650F. For 2019, the bike was transformed into the CB650R, adopting Honda's Neo-Sports Café styling and a long list of updates to the chassis, suspension and ergonomics—changes that sharpened its performance and elevated its overall presence. It received a major front-suspension upgrade for 2021, plus a range of detail improvements to enhance comfort, usability and practicality.
The 2024 model year was important for the CB650R, which received updates to styling and functionality. It also went down in history as the first Honda (along with its CBR650R sibling) to be available with Honda E-Clutch technology.
DESIGN / STYLING
There's an appealing look to the CB650R E-Clutch's retro-minimalism, with the fuel tank given a strong presence above the beautiful inline four-cylinder engine. Tightly wrapped, the model features the signature compact "Trapezoid" proportions, with a sharp tail and short overhang, combined with a slanted LED headlight. All other lighting is also LED, and the taillight is tucked seamlessly into the fairing.
From the radiator shrouds at the front moving rearward, the CB650R's styling is simple, modern and well-proportioned, giving the bike a clean, premium appearance. The long fuel tank serves as a key design element and houses the ignition. A 35° handlebar contributes to easy low-speed maneuvering and U-turns.
The five-inch full-color TFT screen adds to the CB650R's high-quality look and feel, and it uses optical bonding to maximize visibility in bright sunlight. By sealing the gap between the cover glass and TFT screen with resin, glare is reduced, and visibility is optimized. The display itself is customizable between "Bar," "Circle" and "Simple" patterns.
ENGINE / DRIVETRAIN
The 649cc, DOHC 16-valve engine is tuned to create pure, enjoyable midsize four-cylinder performance, with fast pickup through the rev range and a hard-hitting, high-revving top end. Direct cam actuation makes for a compact cylinder head; bore and stroke are 67.0mm and 46.0mm, with a 11.6:1 compression ratio. Iridium spark plugs are employed, while twin air ducts (one on either side of the fuel tank) feed the airbox and produce a throaty intake roar.
Asymmetric piston skirts minimize bore contact and reduce friction. Ferrous spines on the outer surface of the cylinder sleeves reduce oil consumption and improve heat transfer, while a silent SV cam chain with a Vanadium coating on its pins minimizes frictional losses. Most exterior hoses are eliminated through internal water channeling from the cylinder head to the cylinders.
The engine uses a compact internal architecture, stacked six-speed gearbox and starter layout, with the cylinders canted forward 30°. For riders who choose to shift with the clutch lever, an assist/slipper clutch reduces lever effort and also manages rear-wheel lockup under hard braking and rapid downshifts. Honda Selectable Torque Control (HSTC) responds to rear-wheel traction, and it can be turned off should the rider choose.
Honda E-Clutch
Honda E-Clutch takes elements of the technology and performance of quick-shifters, manually operated clutches and Honda's Dual Clutch Transmission to create a unique blend of these proven approaches, opening a new aspect of the motorcycling experience for riders of varying types and experience levels. The clutch and transmission hardware are no different from a conventional motorcycle, and the compact system weighs less than four and a half pounds.
Honda E-Clutch simplifies gear changes by eliminating the need to use the clutch lever for upshifts or downshifts. Riders can simply tap the shift pedal for quick, consistent gear changes, enhancing the overall riding experience. The clutch lever is also not needed when starting from a stop or coming to a halt. Activating as soon as the engine starts, the system prevents stalling and manages these transitions smoothly—boosting rider confidence in stop-and-go urban traffic and on challenging inclines.
Honda E-Clutch manages clutch engagement and disengagement based on its reading of parameters, including vehicle speed, throttle-opening angle, engine rpm, pressure on the shift pedal, clutch-motor reduction-gear angle, engine-countershaft speed and gear position. The clutch is operated through an actuator unit with two motors situated inside the righthand engine cover. As the clutch is engaged or disengaged, the engine's ignition timing and fuel injection are also controlled, resulting in smooth, shock-free shifting in any situation.
The system also allows the rider to select an "operation feel" to set the strength of the force required on the shift pedal to make a gear change. Three settings are available: HARD, MEDIUM and SOFT, each of which can be chosen independently for upshifting and downshifting.
In addition to enjoyment and convenience, Honda E-Clutch brings ultimate flexibility, allowing riders to use the clutch lever manually at any time if they choose. When the clutch lever is used, Honda E-Clutch temporarily pauses, then automatically reactivates—after less than a second at higher engine speeds or after five seconds at lower engine speeds. When E-Clutch is paused, manual operation is indicated by a letter "M" on the instrument panel. The technology also advises the rider to shift down (via a symbol on the instrument panel) if it detects that the motorcycle is in a high gear at a certain speed.
CHASSIS / SUSPENSION
The steel-diamond frame uses pressed swingarm pivot plates and twin elliptical spars with a rigidity balance specifically tuned (stiffer around the headstock and more flexible in the spar sections) to deliver excellent all-around handling characteristics with high levels of rider feedback. Rake is 25.5°, trail is 4.0 inches and wheelbase is 57.0 inches. Curb weight (with all required fluids and a full tank of fuel) is 456 pounds. Seat height is 31.9 inches, and ground clearance is 5.8 inches.
Showa's 41mm Separate Function Fork Big Piston inverted fork (SFF-BP) offers high-quality reaction. A pressure-separation damper in one fork tube and spring mechanism in the other deliver high damping performance and light weight. With the use of a large piston, the combined result is optimized feel, bump absorption and control. Front-wheel travel is 4.7 inches.
Adjustable for 10-stage spring preload, the single-tube monoshock operates directly on the curvy, gravity die-cast aluminum swingarm. Rear-wheel travel is 5.1 inches.
Four-piston radial-mount front brake calipers work 310mm floating discs, and are paired with a single-piston rear caliper and 240mm disc. The ABS is a two-channel system. Cast-aluminum wheels are fitted with 120/70-ZR17 and 180/55-ZR17 front and rear tires.
