Honda CB 750 Hornet
From a press release issued by Honda: The original 1998 CB600F Hornet grew to be a hugely popular bike in Europe, for many reasons. Its compact, naked form was great around town, and it had the engine power and handling ability to carve a section of corners with joyous enthusiasm. Different iterations of the Hornet took it in the direction of sports touring and – in the hands of Hornet Cup racers –an outright race bike, while a 2007 upgrade added extra RR-derived top-end power and much more aggressive style. Every individual owner had a reason why their Hornet was so good, but two things remained constant throughout its life and development: It was great fun to ride. And the fun came with an affordable price tag. 23YM was the perfect time for a new Hornet to land – a bike for the time and a whole new generation of riders. It had big tyre tracks to fill and serious competitors to contend with. None of which was lost on Honda’s development engineers.
This background drove the creation of something quite special -
the CB750 Hornet, a bike which took inspiration and direction from its ancestor
but brought the celebrated Hornet brand right back to the cutting edge. And
packed it with a direct injection of excitement and pure-thrill adrenaline. And, to keep things simple, three words can be used to sum it up: Fast, agile, fun.
For 25YM, the trademark Hornet’s svelte, taut styling is
amplified through a newly developed, powerful light unit. Giving it a look of
its own within the three-bike Hornet family, the CB750’s dual LED dual projector
headlight sits low and centered for a true streetfighter silhouette.
Model Overview 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 (with
new settings for 25YM) 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. Also new is the five-inch TFT colour display which 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. A range of Genuine Honda Accessories, including updated quickshifter, soft luggage, engine protectors and cosmetic enhancements are ready to go. New for 25YM are honeycomb pattern knee grip Tank Pads, Dark Smoke Instrument Visor, headlight stripe, stainless Radiator Grill and loud volume Alarm.
The 25YM CB750 Hornet will be available in the following colour
combinations:
Key Features
- 755cc parallel twin 8 valve unicam engine The parallel twin-cylinder powerplant packs a hugely enjoyable punch to give the Hornet its performance edge. 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. An aesthetic update for 25YM is removal of the breather tube which ran across the engine – it has been re-sited for a much cleaner look. The 270° crank and uneven firing order create a characterful, twin-cylinder pulse feeling. To make the engine as tightly wrapped 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. Engine Electronics
- Three levels of Engine Power, Engine Brake and HSTC with
integrated Wheelie Control
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 new 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 more compact and more powerful than the previous design. The cockpit cowl has been tautly re-shaped to match, amplifying the Hornet’s aggressive streetfighter styling and conveying its engaging, sporty ride. 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 new 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. At a minimum speed of 56km/h, with either brake working if negative acceleration of a minimum of 6.0m/s2 is detected, the hazard lights flash to warn other road users a hard stop is in process. At the same speed the threshold is reduced if ABS is activated, to a negative acceleration of a minimum 2.5m/s2. 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. The rear shock absorber operates through the steel swingarm via Pro-Link and offers 130mm travel. Its design ensures excellent response and temperature management; it features 7-stage preload adjustment to match the forks. Building on the Hornet’s raw sporting appeal for 25YM are the detail changes to the bike’s suspension. Damping settings have been optimised front and rear to maximise the front wheel’s contact patch, for a more dynamic, sportier and engaging ride. 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. Front wheel width is 3.5inch wearing 120/70-ZR17 tyre, the rear 4.5inch with 160/60-ZR17 tyre.
Accessories To make it easy for an owner there are three packs that group the accessories neatly together:
