Euro 5 and chassis upgrade - the Honda CBR 650R (2021)

Honda's versatile mid-range athlete receives Showa's 41 mm Big Piston fork and a EURO5-compliant four-cylinder engine. Other updates include an improved LCD dashboard, revised headlight reflectors and a USB charging socket under the seat. 2014 the sporty, fully faired CBR650F entered the market together with the naked CB650F bike. Thanks to the dynamic four-cylinder engine, the model expanded the range in the medium displacement class for sports bikes. 2017 the CBR650F received a more powerful design that presented the engine even better. In addition, there was more engine power, a Showa Dual Bending Valve front fork and revised Nissin brake calipers. 2019 Honda has further developed the CBR650F to the CBR650R, and put an attractive, sporty and everyday-friendly overall package on the road. The CBR650R serves a niche: a four-cylinder sports motorcycle that is as enjoyable as an RR machine and at the same time offers sufficient practicality and economy. The model has been developed for adrenaline-filled driving fun on the weekend and at the same time for everyday use.

Positioning was well received in the market

In its debut year 2019, the CBR650R was the second best-selling sports motorcycle in Europe. In 2021 the CBR650R will be leveled up again with further improvements, including a significant upgrade for the front suspension. The most important innovation on the CBR650R is the 41 mm Showa Big Piston upside-down fork. It ensures even better driving characteristics. The EURO5 conformity of the engine was achieved without any loss of performance. Other updates include improved visibility of the LCD display, new headlight reflectors and a USB charging socket under the seat. There are also cosmetic changes such as new side panels and a new license plate holder.

2021 CBR650R available in the following colors

• Matte Gunpowder Black Metallic
• Candy Chromosphere Red

Chassis

• New Showa Separate Function Big Piston (SFF-BP) upside-down fork
• Radially mounted four-piston front brake calipers with floating brake discs
• Front and rear tires in dimensions 120/70-ZR17 and 180/55-ZR17

 The steel frame of the CBR650R uses pressed mountings for the swing arm mounting and two elliptical bars with a specially adjusted stiffness balance (stiffer around the steering head area and more flexible in the bar sections) in order to achieve balanced handling properties combined with a high level of driver feedback. The lead is set to 25,5 ° with a lag of 101 mm and a wheelbase of 1.450 mm. The curb weight is 208 kg.

The 41 mm SFF-BP upside-down fork from Showa is new.
A pressure isolating damper in one of the fork tubes and a spring mechanism in the other ensure high damping performance and lower weight. Together with the use of a larger piston, it results in better shock absorption properties and more control. The monoshock shock absorber acts directly on the arched swing arm made of cast aluminum and has a 7-stage spring preload adjustment.

Radially mounted four-piston brake calipers grab the floating 310 mm wave brake discs on the front wheel. They are supported by a single-piston rear brake caliper and a 240 mm brake disc. The CBR650R also has a two-channel ABS system. Tires in the dimensions 120/70-ZR17 (front) and 180/55-ZR17 (rear) are mounted on the cast aluminum wheels.

Styling & Furnishing

• New side panels and new license plate holder
• Revised headlight reflectors
• LCD display now easier to read; USB Type-C charging socket under the seat

The new CBR650R is sporty and attractive:
The four-cylinder engine remains clearly visible, the double LED headlights give the machine a penetrating, aggressive look. In addition, there will be a new, sharp reflector profile in 2021. The fairing of the CBR perfectly combines the muscularity of the machine with its slim lines and edges. The seat is compact and keeps the rear section short, which further emphasizes the sportiness of the machine. New side panels underline the minimalist design, as does the rear splash guard and license plate holder.

The sporty, aggressive riding position begins with the clip-on handlebars, which are mounted under the upper triple clamp and matched to the rear footrests. There is now also a USB charging socket under the seat for easy charging of a mobile device. The seat height is still 810 mm. The stylish LCD instruments include a gear indicator and a gearshift indicator. For 2021, readability has been improved by adjusting the LED angle and font size.

Motor

• 95 HP (70kW) peak power, 63Nm peak torque, with 48 HP (35kW) also A2-capable
• Honda Selectable Torque Control (HSTC)
• EURO 5 compliant

 The 649 cm³ large DOHC 16-valve engine is designed to offer the best possible performance of a four-cylinder engine in this class. It offers all the features that make Honda's inline four-cylinder engines unique. The peak output of 95 PS (70 kW) is achieved at 12.000 rpm, the peak torque of 63 Nm is delivered at 9.500 rpm. A conversion to 2 HP (48kW) is available for owners of the driving license class A35.

The engine specifications for 2021 have been adapted to the EURO5 standard. This required revisions to the ECU, camshafts, intake timing, exhaust, catalytic converter and rear muffler, and the addition of a crankshaft pulse sensor.

The direct actuation of the cams offers a compact design of the cylinder head. Bore and stroke are 67 mm x 46 mm with an increased compression ratio of 11,6: 1. Two channels along either side of the fuel tank supply the airbox with air and create a throaty suction noise. Long-life Iridium spark plugs are installed as standard.

Pistons with asymmetrical piston skirts minimize the friction losses on the cylinder walls. The special shape of the outer surface of the cylinder liners is reduced
the oil consumption and the friction through improved heat transfer. A low-noise SV timing chain reduces friction losses through a vanadium coating. The cylinder head and cylinders are cooled via ducts inside the engine, which means that most of the cooling hoses otherwise routed outside are superfluous.

The in-line four-cylinder with the cylinder bank inclined by 30 degrees has a compact architecture and a raised six-speed gearbox. The slipper clutch favors easy upshifts and makes downshifts smoother. When shifting through the gears in a sporty manner before bends, the locking of the rear wheel is prevented. The Honda Selectable Torque Control (HSTC) is installed to control the rear wheel traction. It can also be switched off at the request of the driver. The fuel consumption is 4,9 l / 100km (WMTC mode). With a capacity of 15,4 liters, one tank of fuel allows a range of over 300 km.
