Honda CB 750 Hornet
From a press release issued by Honda: The Hornet’s engine packs a great deal of Honda’s engineering prowess into a small space. Headline numbers: 755cc parallel twin-cylinder, 67.5kW peak power and 75Nm torque. With wet weight of 192kg (E-Clutch – 196kg) it has a class-leading power-to-weight ratio of 0.35kW per kg / 2.84kg per kW. Compact, competition CRF-derived Unicam eight-valve cylinder heads employ downdraft air intakes and a Vortex Flow Duct to ensure optimal combustion. A 270° crank delivers feel and character; the primary drive doubles as balance shaft while an assist/slipper clutch manages a six-speed gearbox. Electronic rider aids thanks to Throttle By Wire (TBW) include three riding modes (plus USER mode), three-level Honda Selectable Torque Control (HSTC), Wheelie Control with three-level Engine Power and Engine Braking adjustment.
To maximise the engine’s potential, it’s housed in a steel diamond frame, which is extremely light weight thanks to optimisation of wall/pipe thickness and stiffness. For optimal agility and rider feedback, suspension is top quality: Showa 41mm SFF-BPTM USD forks and rear shock operating through Pro-Link. Dual four-piston, radial-mount calipers stop hard while the tyres are sized to provide perfect levels of grip and agility – a 120-section front matched to 160 rear. 26YM saw the introduction of Honda E-Clutch as an option, which works with the sophistication of TBW provides some key advantages for the CB750 Hornet. Starting and stopping in the city is so much easier, and less tiring, by not having to use the clutch lever. More importantly, the system provides next level riding enjoyment, working much more quickly and smoothly than a quickshifter, up and down the gearbox. Honda E-Clutch CB750 models also benefit from the addition of a stylish, svelte undercowl that seamlessly blends in to the Hornet’s signature aggressive, purposeful styling. The CB750 Hornet’s minimalism is led by a low-set, centrally mounted dual LED projector headlight, tautly wrapped and oozing streetfighter style. The CB750 Hornet owns a style that is distinct from its larger and smaller siblings, carving out an identity all its own. A five-inch TFT colour display supplies vivid information delivery and management of all systems, as well as the connectivity of Honda RoadSync system for both Android and IOS devices. It’s operated, easily, by a four-way toggle switch on the left handlebar. 26YM saw the range of Genuine Honda Accessories updated too, with new soft luggage, engine protectors and cosmetic enhancements added to the line-up. Also new for 26YM were updated honeycomb pattern knee grip Tank Pads, full-body graphic stickers, and the Under Cowl for non Honda E-Clutch models.
The 27YM CB750 Hornet and CB750 Hornet E-Clutch will be available
in the following bold colour combinations: Key Features
Engine The parallel twin-cylinder powerplant packs a hugely enjoyable punch to give the Hornet its performance edge and is unchanged for 27YM. It’s designed for every rider to exploit to the maximum, with exhilarating peak power output, but also to deliver accessible low to mid-range usability – perfect for the less experienced, and a major boost to the enjoyment of everyday town riding. 755cc, with an 8-valve Unicam cylinder head it pumps out 67.5kW @ 9,500rpm with 75Nm torque @ 7,250rpm. Bore and stroke is set at 87 x 63.5mm with compression ratio of 11.0:1. Compact and lightweight (and a configuration used by the MX competition-ready CRF450R) the Unicam head operates the 35.5mm inlet valves via cam, and the 29mm exhaust by rocker arms. Inlet lift is 9.3mm, exhaust 8.2mm. For razor-sharp pick-up and throttle response patented Vortex Flow Ducts create a more uniform distribution from the side scoops into the airbox, which then feeds downdraft intakes and 46mm diameter throttle bodies. The 270° crank and uneven firing order create a characterful, twin-cylinder pulse feeling. To make the engine as compact as possible there’s no balancer drive gear; the primary drive gear doubles up duties and spins the balance shaft. The water pump is tucked away inside the lefthand engine cover and there’s no need for a water-cooled oil-cooler. The cylinders also use a Ni-SiC (Nickel-Silicon Carbide) coating, as also used in the CBR1000RR-R Fireblade and CRF450R. An assist/slipper clutch – with oblique layout disc segments – offers light lever feel, eases up shifts and manages rear wheel hop under hard braking and rapid down changes. Fuel consumption of 23km/l (WMTC mode) offers a potential range of over 340km from the 15.2L fuel tank. A 35kW, A2 licence option is also available.
Engine Electronics There are three levels of Engine Power (EP), Engine Brake (EB) and Honda Selectable Torque Control (HSTC) with integrated Wheelie Control available; HSTC can also be switched off. The riding modes offer different combinations of each parameter. SPORT uses level three EP and level one EB and HSTC to deliver maximum performance with minimum intervention.
STANDARD mode is a mid-way setting that uses level two setting
for EP, EB and HSTC. USER1/ USER2 modes allow the rider to choose between the three settings for each parameter and save the setting for future use.
Styling & Equipment
- Hornet style defines razor-sharp minimalism The main signature of the Hornet is the fuel tank, which takes inspiration from the shape of a hornet’s wing. Everywhere you look, from the aggressively angled nose-fairing to the razor-sharp, minimal tail, there are hallmarks of tension and aggression, outlining true sporting intent. Up front the headlight unit – comprising dual high/low unified projector lenses – is unique within the Hornet family. With a look of its own within the Hornet family, the LED unit is both compact and powerful. The cockpit cowl amplifies the Hornet’s aggressive streetfighter styling while conveying its engaging, sporty ride. For 26YM, the CB750 Hornet with Honda E-Clutch gained an all-new undercowl that tied together the naked style of the bike, seamlessly integrating with the aggressive styling of the tank and frontal mask without interrupting airflow, and ultimately, the bike’s balance and poise. The svelte part is also available as an optional extra on the standard model. Usability, for all riders, is also inherent to the design. Seat height is a very manageable 795mm and the riding position upright, with slightly rear set footpegs for natural control and wide handlebars for leverage. The five-inch full colour TFT screen uses optical bonding to improve visibility in bright sunlight. By sealing the gap between the cover glass and TFT screen with resin, glare is reduced, and backlight transmittance improved. The IOS/Android smartphone connectivity of Honda RoadSync – alongside a simple, easy-to-use, backlit four-way toggle-switch on the left handlebar – allows straightforward, on-screen turn-by-turn navigation as well as the option (via a Bluetooth helmet headset) for the rider to make calls or listen to music. All an owner has to do is download the Honda RoadSync app from either the Play Store or the App Store, connect to the CB750 Hornet, and go. To simplify and miniaturise the entire electrical system the Hornet uses a Controller Area Network (CAN) alongside a Body Control Unit (BCU). The rear indicators have an Emergency Stop Signal (ESS) function. Both front and rear indicators also auto-cancel; rather than using a simple timer, the system compares front and rear wheel speed difference and calculates when to cancel the indication relative to the situation.
Chassis The Hornet’s steel diamond frame is lightweight, at just 16.6kg (for comparison, the CB650R’s is 18.5kg). A major technological process of stiffener, main/down tube thinning, and pivot shape optimisation has produced a hugely strong platform, with rigidity balance to deliver feel and geometry set for agility – just what the engine needs. Rake and trail are set at 25° and 99mm, with wheelbase of 1,420mm and kerb weight of 192kg (Honda E-Clutch – 196kg). With a view to heighten sports handling performance (especially braking from higher speeds) Showa 41mm Separate Function Fork Big Piston (SFF-BPTM) USD forks are clamped by Hornet-specific top and bottom yokes. With 130mm travel and by dividing the functions – Big Piston pressure separation damper in one leg, spring mechanism in the other – maximising both reaction over changes in road surface and the overall ride quality. The rear shock absorber operates through the steel swingarm via Pro-Link and offers 150mm travel. Its design ensures excellent response and temperature management; it features seven-stage preload adjustment to match the forks. Damping settings are optimised front and rear to maximise the front wheel’s contact patch for a more dynamic, sports riding experience. Dual front 296mm discs and Nissin radial-mount, four-piston calipers deliver impressive, fingertip stopping power, with excellent progressive feel through the lever. To further elevate handling and ride quality lightweight wheels use Y-shaped spokes. The 3.5inch width front wheel wears a 120/70-ZR17 tyre, the rear 4.5inch a 160/60-ZR17 tyre.
Honda E-Clutch
Available as an option from new 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. 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. And, with the CB750 Hornet’s Throttle By Wire (TBW) control, Honda E-Clutch offers an even greater advantage, especially on downshifts. When the half-clutch position is activated TBW blips the throttle, matching engine revs to rear wheel speed for even smoother shifting. Honda E-Clutch also adjusts the throttle butterfly opening range depending on riding mode selection. For instance, RAIN mode is suitable for extreme weather conditions, SPORT heightens the experience, for maximum enjoyment and riding pleasure. The system also detects rear wheel ‘hop’ under rapid downshifting and braking and employs half-clutch to stabilise the situation. The rider can also 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 system 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 five 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. For extra legroom on the CB750 Hornet, the mounting structure of the Honda E-Clutch has been adjusted by dividing the clutch lifter shaft in two and adding a gear train, offsetting it 40mm away from the foot. Also, the anti-vibration rubber and stays of the standard clutch cover design were found to be unnecessary in testing, following optimization of the engine cover design, ultimately saving 300g.
Accessories Overhauled for 26YM, the range gained new colour-matching Under Cowl for non E-Clutch variant, and decorative stickers with Kanji inspired graphics. To make it easy for an owner there are four packs that group the accessories neatly together:
Style Pack
Sports Pack
Comfort Pack
Design Pack Additional accessories include Side Bags, Rubber Side Tank Pads and a SC-Project Slip-on muffler (Customized EU accessory).
