2027 Honda CMX500 Rebel – In depth

The CMX500 Rebel, Honda’s hugely popular A2 licence-friendly 500cc parallel twin-cylinder compact cruiser, is updated for 27YM courtesy of an all-new 3.5” circular TFT display featuring crisper graphics and a more intuitive design, paired with a new six button module on the lefthand handlebar. Everyday useability is boosted through the addition of Honda E-Clutch technology, whilst an overhauled colour palette rounds out the 27YM changes. Standard specification includes assist/slipper clutch, LED lighting and gear position indicator.

1. Introduction

For many riders in their early 20s – Generation Z, who have grown up through the digital age – motorcycles mean so much more than just transport. They need to represent a lifestyle, an attitude, and allow them to express their own individual identity.

These riders’ expectations are different to those of the motorcycling mainstream and the machines that speak to them reflect this. They must fit in with their life but also contain the potential for further individualisation. Fusing tradition and ground-breaking new ideas and perspectives, the CMX500 Rebel set out to be that motorcycle.

Showcasing a classic, timeless look but imbued with a forward-looking, contemporary style all its own, the CMX500 Rebel was an instant hit on its introduction in 2017 and has been popular ever since, becoming the best-selling European model in the ‘custom’ category every year since 2021.

For 20YM, its ergonomics and practicality were boosted thanks to a revised seat and suspension settings, and the introduction of a gear position indicator. Both the headlight and taillight were new, and the addition of LED indicators meant all lighting became LED. A revised exhaust system, including new exhaust sensor, ensured EURO5 compliance. 21YM saw the Rebel family expand across Europe with the introduction of the CMX1100.

Accessible, easy to ride and easy to live with, the CMX500 Rebel goes its own way but also acts as blank canvas, ready for whatever its owner’s imagination has in store. It received some minor 25YM updates to keep it fresh and for 27YM it debuts a ‘second-generation HMI’, which comes with richer graphics and data relay, an improved user experience, and all-new features. The left-hand control system moves from four buttons to six, and for the CMX500 Rebel, this is all packed in to an all-new circular 3.5” TFT screen, in keeping with the custom aesthetic. Also new is the addition of Honda E-Clutch technology, bringing increased everyday versatility and comfort on the urban commute or out on the open road at a weekend. 27YM changes are rounded out by a revised palette of standard paint choices, for both the standard and ‘S’ Edition models.

2. Model Overview

Development of the Rebel began in North America, with an outlook geared toward firing the imagination of a younger generation of riders in a different way to traditional cruiser motorcycles. Powered by a 471cc parallel twin-cylinder engine, with strong bottom end torque and a smooth, linear power delivery, the Rebel is A2 licence friendly. For 25YM the engine was updated with new ECU settings and the addition of an OBD2-2 exhaust sensor.

The Rebel has been designed to be a slim motorcycle with a low seat height making it easy and unintimidating to manage at low speeds. Updated and improved for 25YM, the riding position is relaxed and neutral, with gently outstretched arms matched to mid-mounted footpegs.

The CMX500 Rebel’s tubular steel frame draws fresh, contemporary lines into stripped-back, fat-tyred ‘bobber’ style. Blacked out to the maximum, with the minimum of paint, it switches from solo-only to pillion-possible via two bolts.

Making its debut on the model for 27YM, a new 3.5-inch circular TFT display replaces the previous 100mm negative LCD dial. Featuring crisper resolution and revised graphics, it pairs with an all-new six-button control system to deliver enhanced functionality and more intuitive operation.

27YM sees the introduction of Honda E-Clutch technology, for increased everyday versatility and comfort, whether on the urban commute or taking on twisty roads on a longer run. The new colours and increased flexibility ensure the CMX500 Rebel continues its journey into the hearts and minds of European riders.

The 27YM CMX500 Rebel will be available in the following colour options:

• **NEW** Mat Fresco Brown
• Mat Gunpowder Black Metallic

The 27YM CMX500 Rebel ‘S’ Edition will be available in the following colour option:

• **NEW** Candy Rosy Red
• Mat Gunpowder Black Metallic

3. Key Features
    3.1 Styling & Equipment

• All-new 3.5” circular TFT screen debuts on the 27YM CMX500 Rebel
• New unit features improved graphics, richer data relay and all-new control system on the left-hand side bar
• Lean and low ‘bobber’ styling an exercise in minimalist design
• Rider’s seat now more comfortable; pillion pad and rear pegs easily removed for customisation
• Factory-fitted Genuine Honda Accessories ‘S’ option remains available

Two key words ran throughout the Rebel’s development programme: ‘Simple’ and ‘Raw’. But to do so much with so little is an art form in itself; an exercise in minimalist design where every detail matters.

And the 27YM Rebel does not disappoint; rolling on fat tyres, a low and lean ‘bobber’ silhouette crowned by the signature steeply raked 11.2L fuel tank, and newly optimised for comfort fat handlebars. From every angle of its stripped back form, it expresses an off-beat individuality. There were subtle updates for 25YM; the front mudguard was switched to painted steel, rather than coloured resin, while the rear resin mudguard carried a wider range of colours.

Everything that can be is blacked out, accentuating the Rebel’s lithe design as well as underlining the subtle paintwork. All lighting is LED, and the evocative round headlight features a compact 175mm diameter lens and die-cast aluminium mount. The ultra-thin oval tail-light and licence plate light match the Rebel’s low-down stance; mini circular LED indicators measure only 55mm in diameter, with a circular position light included in the front indicators.

Rider comfort was improved for 25YM through the use of a new urethane foam material for the seat. Both pillion pad and rear footpegs are easily removed to help transition between pillion and single occupancy, as well as allowing a range of accessories from the comprehensive line-up to be fitted. Optional extras include a rear rack, backrest, tank pads, high screen, nylon or leather saddlebags and much more.

Headlining the updates for 27YM is the introduction of a new 3.5-inch circular TFT display, making its debut on this model and replacing the previous 100mm negative LCD dial. It offers sharper graphics and a more premium user experience. Paired with an all-new six-button control system, the system offers faster, more intuitive operation

The ‘S’ edition continues for 27YM and comes complete with factory-fit headlight cowl with smoke screen, retro front fork covers and gaiters and a special brown diamond-stitch style seat and bronze wheels. All are available individually.

3.2 Engine

• 471cc liquid-cooled parallel twin-cylinder engine, A2 licence compatible
• Torque heavy bottom-end delivers an effortless ride
• 120mm ‘shotgun’ style exhaust provides a suitable cruiser soundtrack

The 471cc 8-valve, liquid-cooled parallel twin-cylinder engine is drawn from the sporty CBR500R. For cruising duties, revised PGM-FI fuel injection mapping as well as different valve and ignition timings mean its character is shifted away from the high rpm-focused performance of the CBR to a torque-heavy bottom-end output, with smooth and linear delivery throughout the rev-range. Punchy maximum torque of 43.3Nm torque @ 6,000rpm combines with peak power of 34kW @ 8,500rpm.

It’s a power unit that strikes a great balance between physical size and flexible output. Bore and stroke is set at 67mm x 66.8mm respectively, with compression ratio set at 10.7:1. Internally the cylinder head uses roller rocker arms; shim-type valve adjustment allows them to be light, for lower valve-spring load and reduced friction.

A silent (SV Chain) cam chain has the surface of its pins treated with Vanadium, reducing friction with increased protection against dust. Inlet valve diameter is 26.0mm with exhaust valve diameter of 21.5mm.

Friction is reduced by the addition of striations on the piston skirt (a finish that increases surface area, introducing gaps in which oil can flow for better lubrication). An AB 1 salt bath process, used after isonite nitriding, forms a protective oxidisation membrane.

The crankshaft pins are phased at 180° and a primary couple-balancer sits behind the cylinders, close to the bike’s centre of gravity. The primary and balancer gears use scissor gears, reducing noise. The crank counterweight is specifically shaped for couple-balance and its light weight allows the engine to spin freely, with reduced inertia.

The crankcases use centrifugally cast thin-walled sleeves. Their internal design reduces the ‘pumping’ losses that can occur with a 180° phased firing order. A deep oil sump holds 3.2L. Slick to use up or down, the six-speed gearbox is designed to offer effortless changes, especially around town. An assist/slipper clutch makes the shift lighter and smoother, and controls rear wheel ‘hop’ on rapid downshifting.

The 2-1 exhaust scrubs spent gases in its catalyser, which then speeds them through its first chamber into the second resonator chamber; the sound produced has a heavy-duty pulsing feel that fits the torque delivery and exits through a 120mm diameter ‘shotgun’ style muffler.

3.3 Chassis

• Low slung tubular steel frame with newly optimised handlebar position
• Compliant, supple damping front and rear; shocks nitrogen charged with revised bump stop rubbers
• 130/90-16 front and 150/80-16 rear tyres

Facilitating the Rebel’s low-slung look is an attractive tubular steel frame that grips the engine in three places. Designed to be as narrow as possible around the rider’s inseam, the frame includes an innovative rear loop that separates the thicker seat from the textured metal mudguard. At the rear, the bolt-on cast aluminium subframe provides further scope for customisation.

Trail is set at 110mm with 28° rake; the 30° off-set of the forks, combined with a 1490mm wheelbase allows for a low 690mm seat height. The Rebel’s footpeg placement ensures a natural, comfortable riding position, with balanced and neutral steering. The handlebar position was finely tuned for 25YM to further rider comfort.

At 230mm apart, the 41mm front fork stanchions are set wide for handling rigidity, comfort and style; spring rates and oil volume are optimised to give compliant damping and a smooth ride. The tubular steel swingarm has a 45mm diameter and works twin, nitrogen-charged shock absorbers that feature 5 step preload settings and revised bump stop rubbers that have been re-profiled for a smoother ride.

Dunlop tyres are fitted as standard sized 130/90-16 front and 150/80-16 rear. The classical style of the 16-inch cast aluminium wheels is crisp and simple, with the 296mm front disc acting as mirror to the spoke pattern. A twin-piston front caliper is matched by a single-piston rear.

4. Honda E-Clutch 

• Advanced Honda technology that brings ‘next level’ sporty riding performance
• Also allows the rider to start, stop and change gear without using the clutch lever – just the gear shift pedal
• Honda E-Clutch also allows normal operation of the clutch lever
• Brings more enjoyment and flexibility across a wide range of scenarios, for a ‘next level’ riding experience

The Honda E-Clutch system – which debuted on the 24YM CB650R and CBR650R – brings ‘next level’ riding enjoyment and performance, allowing consistent gear changes that are faster and smoother than a quickshifter. For the first time, it will now be available on a Rebel family member – giving more young riders the opportunity to sample class-leading technology and sporty riding.

As well as performance, it offers simplicity of operation. The clutch lever is not needed when pulling away or coming to a stop and there’s no need to use the lever to make a shift either up or down the gearbox. The rider simply operates the shift pedal to change gear.

A half clutch position smooths the up/down shift, and the engine’s ignition timing and fuel injection are also controlled, based on parameters such as 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 operation itself is performed through an actuator unit with two motors situated inside the right-hand engine cover.

The Honda E-Clutch 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. The technology will also advise the rider to shift down – via a symbol on the instrument panel – if it detects the motorcycle is in a high gear at a certain speed.

And the system is the ultimate in versatility, as the clutch lever can be used as normal at any time. After use, the Honda E-Clutch system will re-activate after less than a second above a certain engine rpm, and after 5 seconds at lower engine speeds. Should the rider wish to turn off the system for a particular ride, this is also possible via the switchgear on the left handlebar, once the vehicle is stationary and in neutral. The change to manual operation is indicated by a letter ‘M’ on the instrument panel.

Junya Ono, Large Project Leader, Honda E-Clutch: “Our Honda E-Clutch is designed to offer motorcyclists a new kind of experience that can make their riding even more fun and exciting. It also adds peace of mind and comfort to town riding or the daily commute. We hope that many riders will try this system to enjoy the unique mix of sportiness and flexibility it offers.”
