Along with the naked CB650F, Honda’s wholly faired CBR650F was introduced in 2014 and offered a sizable chunk of four-cylinder middleweight performance that was firmly at the sporty end of the “sports touring” range. In 2017, it gained a more angular look that drew attention to the engine more. It also received an increase in peak power, a Showa Dual Bending Valve front fork, and updated Nissin brake calipers.
The CBR650F underwent an upgrade in 2019 and became the CBR650R. The upgrade from “F” to “R” denotes a shot of sporting ability that is considerably more powerful and intended to be tested, utilized, and enjoyed on the street.
The CBR650R was intentionally transformed into a rare breed: a four-cylinder sports bike that offers equal enjoyment, pleasure, and adrenaline to an RR machine, while being sufficiently practical and having reasonable operating costs to make it a viable option for both weekday transportation and weekend fun.
It’s a direction that people seem to like. The 2021 CBR650R Honda Sports Motorcycle was the second best-selling sports bike in Europe in its first year of 2019. The 2021 CBR650R Honda Sports Motorcycle continues to advance with user-driven minor upgrades and a significant front suspension change.
Showa’s new 41mm Separate Function Big Piston forks and EURO-5 compliance for the high-revving four-cylinder engine are added to Honda’s versatile middleweight sports bike. Other upgrades include a better LCD dash, updated visual design, updated USB Type-C connector, and reworked headlight reflectors.
2021 CBR650R Honda Sports Motorcycle – Features and Specs
Chassis
To achieve balanced handling characteristics and high levels of rider feedback, the steel diamond frame uses pressed swing arm pivot plates and twin elliptical spars, including a rigidity balance that has been specifically tuned (stiffer around the headstock and more flexible in the spar sections). With a trail of 101 mm and a wheelbase of 1,450 mm, the rake is set at 25.5-degree. 208 kg is the kern weight.
A pressure separation damper in one fork tube and a spring mechanism in the other give excellent damping performance and less weight in the Showa 41mm SFF-BP USD forks, which significantly improve. Improved feel, bump absorption, and control result from an oversized diameter piston. The single-tube mono-shock, which has a 7-stage spring preload adjustment, functions straight on the curved gravity die-cast aluminum swing arm.
A single-piston rear caliper and 240 mm of the disc are combined with the four-piston radial-attached front brake calipers that operate on 310 mm wave-pattern floating discs. An all-new two-channel system ABS comes standard in 2021 CBR650R Honda Sports Motorcycle.
Front and rear tires measuring 120/70-ZR17 and 180/55-ZR17 respectively are fixed on cast aluminum wheels.
Styling & equipment
The CBR650R’s wrapping amplifies the pure racing appeal since it makes the four-cylinder power unit visible. Dual LED headlamps generate a piercing, stern look, and the upper and (expanded) lower fairings merge muscularity with sleek lines and angles.
The seat unit also contributes to the machine’s hard-edged feeling of purpose by being small and truncating the back. Adding new side panels and the steel rear mudguard/number plate mount emphasize the minimalist design.
The clip-on handlebars that install behind the top yoke and are paired with rear-seat foot pegs are the foundation of the aggressive riding stance. A USB Type-C port comes added beneath the seat for humble mobile device charging. The seat height is still 810mm.
Shift Up, Gear Position, and Peak Hold indications are included on the fashionable LCD instruments. With a modification in LED angle and letter size for 2021, readability has been enhanced.
Engine
The new DOHC, 16-valve, 649cc engine is developed to provide the cleanest, most pleasant mid-sized four-cylinder performance imaginable, with the renowned quick ‘pick-up’ across the rev range and hard-hitting, high-revving top end of Honda’s in-line fours. Peak torque of 63 Nm is supplied at 8,500rpm, while peak power of 70kW comes at 12,000rpm. A2 license holders feature access to a humble 35kW conversion.
The only update in engine specifications until the 2021 update is those necessary for EURO-5 compliance, known for adjustments to the ECU, cam lobes, intake timing, exhaust pipe, catalyzer, silencer, and crank pulsar.
Compact cylinder heads are delivered by direct cam actuation; the diameter and stroke are set at 67mm x 46mm, respectively and the compression ratio is improved to 11.6:1. Twin air ducts, one mounted on each side of the gasoline tank, feed the air box and offer a throaty intake roar. Iridium spark plugs are used.
Asymmetric piston skirts reduce friction by minimizing bore contact. Thanks to enhanced heat transmission, ferrous spines on the outside of the cylinder sleeves reduce oil consumption (and conflict), and the pins of the quiet SV cam chain have a vanadium coating to lessen frictional losses. Most of the outside hoses are eliminated by internal water channeling from the cylinder head to the cylinders.
The engine has a small internal structure, a stacked six-speed transmission, and a starting design with the cylinders canted forward by 30 degrees. An assist/slipper clutch manages rear-wheel lockup under heavy braking and quick downshifts while easing upshifts. Rear wheel traction is organized by Honda Selectable Torque Control (HSTC), which may be disabled at the rider’s discretion.
With a fuel consumption rate of 20.4 km/l (WMTC mode), the 15.4-liter fuel tank can go more than 300km.
