After a fundamental redesign in 2019, Honda's A2-compatible “Pocket Rocket” will receive an aggressive and, above all, aerodynamically focused make-over for 2020. The CBR500R is now also homologated for EURO5. Fast, economical, affordable and inexpensive to maintain: Honda's fully faired CBR500R - launched in 2013 together with the naked version CB500F and the adventure-trimmed CB500X - is the sport star in the two-cylinder trio from the “light / middleweight” category. The CBR500R gives riders stepping off smaller machines the exciting feeling of owning a real sports bike, and that with every ride. At the same time, the low maintenance costs and the versatility are surprising: with the CBR500R you can commute to work and enjoy the weekend at the same time. In addition, the CBR is also popular with experienced drivers who want to downsize without sacrificing driving pleasure.

In 2016, the CBR500R received sharper styling, LED lighting, and upgrades to the front suspension. In 2019 there was an even more aggressive makeover with a new shape and a sportier seating position. The engine has also been further improved: more power in the lower speed range, a strong acceleration across the entire speed range into the red area and an even more distinctive sound were the result.

Model overview

Dynamic lines, slim and muscular at the same time, define the look of the CBR500R. The design is pure ergonomics, geared towards the sporty driver and is characterized by excellent aero management. Handlebar stubs below the revised, upper triple clamp enable a sitting position that is more forwardly inclined than that of the two CB500 siblings. The 35 kW motor of the CBR500R is compatible with the class A2 driver's license and benefits from the 2019 upgrades to inlet and outlet as well as valve timing. This resulted in - compared to the previous model - 4% more power and torque between 3.000 and 7.000 revolutions per minute. In addition, the CBR was equipped with an improved exhaust system and an anti-hopping clutch. The LCD instruments have a gearshift indicator and a gear indicator, the entire lighting consists of LEDs.

Styling & chassis

  • Aggressive lines with double LED headlights
  • Improved aerodynamics, ergonomic seating comfort
  • sporty seating position thanks to the handlebars
  • LCD instrument display, with gear display and gear shift indicator
  • complete LED lighting

Since further development in 2019, the fully faired CBR500R provokes with a super aggressive styling. Straight, wedge-shaped lines and side panels extended downwards symbolize speed. The slim-cut cladding and bench improve ergonomics and freedom of movement. Aggressively designed LED double headlights stare menacingly forward, LED turn signals complete the sporty front.

The view ahead, over the cockpit of the CBR500R, is pure sport. The handlebars are mounted under the upper triple clamp and the seating position leaves no room for doubt: here you are sitting on a sports bike! The CBR's fairing is set low, giving the rider the control and stability that Honda athletes are famous for.

The LCD instruments have a gear display and gear shift indicator; this is set to 8.750 rpm by default, but can be readjusted between 5.000 and 8.750 rpm in steps of 250 rpm.

The tubular steel frame with a diameter of 35 mm is light and stable. It gives the driver good feedback in changing road conditions. The shape and position of the engine mounts, as well as the rigidity balance of the frame, reduce vibration.

The wheelbase is 1410 mm, the inclination and caster are set to 25,5 ° / 102 mm, which enables direct and trustworthy steering. The mass centralization, in which the engine is in the immediate vicinity of the pivot point, ensures improved maneuverability, while the optimal weight distribution between the front and rear axles ensures stability. The weight (full tank) is 192 kg.

The seat height is comparatively low at 785 mm, which makes the CBR500R very easy to handle, and the neutral seat position suits drivers of all sizes. The overall dimensions are 2080mm x 755mm x 1145mm, with a ground clearance of 130mm. The fuel tank has a capacity of 17,1 l including a reserve. The engine's excellent fuel consumption of 3,5 liters per 100 km results in a range of 480 km.

The 41 mm telescopic front fork with 120 mm stroke provides a pleasing yet controlled driving behavior and provides a good feeling for the front tire. A monotube rear shock absorber (as found on larger-capacity sports motorcycles) with a large piston diameter ensures excellent suspension behavior and temperature management. It has a 9-stage spring preload adjustment and works via a rigid steel rocker with a box profile, which is equipped with pressed steel chain adjustment end pieces. The final drive is via a sealed 520 chain.

The CBR features lightweight 17-inch cast aluminum wheels with Y-shaped spokes and hollow sections. The width of the front wheel is 3,5 inches, it is equipped with a tire in the dimension 120/70-ZR17. The width of the rear wheel is 4,5 inches, this is equipped with a tire of size 160/60-ZR17. A single 320 mm wave brake disc at the front with a two-piston brake caliper is matched to a 240 mm rear disc with a single-piston brake caliper. ABS is installed as standard.

The CBR500R will be available in the following color options:

  • Matt Axis Gray Metallic
  • Grand Prix Red
  • Pearl Metalloid White

Engine of the Honda CBR500R

  • Lively two-cylinder power plant related to the 2019 CBR1000RR Fireblade
  • Power and torque over the entire range
  • Sportier sound thanks to the dual exit silencer
  • Anti-hopping clutch facilitates upshifting and downshifting
  • Now EURO5 homologated

The A2-capable CBR500R with 8 valves in a liquid-cooled parallel twin offers a balanced ratio between motor size and willing, pleasant power output, with an energetic and willing turning character right up to the top.

The 2019 engine upgrades improved acceleration by increasing power and torque in the low to medium speed range from 3.000 to 7.000 rpm; an improvement of 4% due to a modified valve control - with valve timing closing 5 ° earlier - and a valve lift that has been increased by 0,3 mm to 7,8 mm.

The PGM-FI fuel injection is fed more or less in a straight line by the airflow through the airbox and throttle bodies - the 2019 upgrade moved the battery further away from the back of the airbox's intake duct to allow for greater airflow. The muffler has double outlet pipes, which give every impulse a sporty sounding note. The peak power of 35 kW is achieved at 8600 rpm, the torque of 43 Nm is available at 6500 rpm.

Bore and stroke are 67 mm x 66,8 mm, the compression ratio is 10,7: 1; the crankshaft journals are offset by 180 °, and a primary balancer shaft sits behind the cylinders, near the center of gravity of the motorcycle. The primary drive as well as the drive of the balance shaft use scissor wheels, which reduces noise. The crankshaft balance weight is specially shaped for torque balancing and its low weight allows the engine to rotate freely and with reduced inertia.

As a loaded element, the engine contributes to the rigidity of the frame through four frame suspensions on the cylinder head. Roller rocker arms are used inside the cylinder head; which can be particularly light due to the valve clearance adjustment via shims, which in turn reduces the valve spring load and reduces friction.

The smooth-running timing chain (SV Chain) is made with vanadium-treated pins, which reduces friction and increases wear protection. The inlet valve diameter is 26,0 mm and the outlet valve diameter is 21,5 mm.

The piston shape is based on the pistons used in the 2019 CBR1000RR Fireblade to reduce “piston noise” at high RPM. Friction is reduced by grooves on the piston skirt (a finish that increases the surface area and allows oil to flow in the channels created for better lubrication). As with the CBR1000RR, an AB1 salt bath process, which is used after isonite nitration, forms a protective oxidation membrane.

The "triangular" relationship between the crankshaft, main shaft and countershaft is very similar to that of the four-cylinder RR engines from Honda, with much of the internal structure and technology being taken directly from the 2019 CBR1000RR.

The crankcase uses thin-walled centrifugally cast bushings whose internal construction reduces the pumping losses that can occur with a 180 ° firing order. The oil pump is characterized by an improved ventilation performance with reduced friction; a deep sump reduces oil movement when cornering hard and when braking. The oil capacity is 3,2 L.

The six-speed transmission on the CBR500R is very similar to that of its RR cousin and uses the same shift arm structure and linkage mechanism. An anti-hopping clutch introduced in 2019 enables easier upshifts and smooths hard downshifts.

The CBR500R, like its 500 cc stable companion, is homologated for the EURO5 standard. This came into force on January 1, 2020 and - compared to the EURO4 standard - stipulates significantly stricter emissions values ​​for engines. These requirements include a significant reduction in allowable carbon monoxide emissions, a reduction in total hydrocarbon emissions of more than 40%, more stringent misfire detection and the introduction of a limit value for particulate matter.
