Honda is founded on innovation. In keeping with this tradition, in recent years, from deep within the company came the desire to create a new machine that would push boundaries, with an identity, riding feeling and experience that could and would place it in a class of its own.
A ground-breaking machine inspired by the desire to establish a unique riding experience and an identity not bound by standard motorcycle design, with strong echoes of futuristic
bikes seen in Japanese movies. Created by a young design team who remained true to their original concept at every stage through to production, the NM4 brings radical style to the streets, with function from the future for a new breed of rider.
The visual creative spark was fired by the futuristic bikes seen in the anime and manga* television and film styles. Known collectively as ―Japanimation‖, in Japan both genres have long been very grown-up entertainment, woven into the fabric of life; now, the philosophy, attitude, fashion and feeling are worldwide and mainstream phenomena.
Another critical factor in the genesis of this new entity was a desire to create a machine capable of crossing traditional two-wheeled lines and reach out to a wider audience. The creative team of engineers who conceived, designed and put it together are in their 20s and early 30s. They were given a completely free hand. In that respect, the NM4 represents a leap of faith from Honda, one intended to appeal to and attract a new kind of rider. We predict that those that want it will want it now, and what will really captivate them is the look and how it makes them feel. The NM4 is real, like nothing else, and it is coming.
Mr Keita Mikura, Large Project Leader (LPL) NM4:
―Honda is a big company. We make every kind of motorcycle. It‘s great that sometimes we make a certain machine simply because we can and because we want to, not because we ―"should".
The NM4 exists because of a passion from deep within our company. We wanted to create something special, not just in the two-wheeled world, but truly unique in the whole world - a machine that engages a human soul like no other.
Our intention was to make something that makes every moment feel cinematic, and we want riding it to be an event - guaranteed – every single time.‖
*anime – Japanese abbreviation of “animation”; manga – 漫画 literally: impromptu drawings, sketches.
The young social media-engaged urbanite lives a digital existence in a fast moving world. They are totally engaged by the new and without question, the NM4 is just that. It is avant-garde in both the way it looks but also, and perhaps more importantly, in the detail work that has gone into creating a unique riding experience. The reactive dashboard – with colours that change depending on driving mode – and flip-up passenger seat that acts as rider backrest – and fully integrated saddlebags are just a few examples.
The NM4, with its LED lights, future-shock style and stealth bomber silhouette presents a look that will not have been seen in any cityscape this side of an anime movie.
Underneath the brooding menace is a rock-solid chassis and engine package. Packed with low-friction technology, its 700cc class twin-cylinder engine is canted forward, creating space and a low centre of gravity. It is specifically tuned to deliver strong low and mid-range power and torque for smooth acceleration coupled with excellent fuel economy.
The NM4 comes standard with Dual Clutch Transmission (DCT), giving the rider options between automatic twist-and-go D and S mode – plus trigger-operated computer game-style manual MT mode. Intuitive and easy to use, it adds to the futuristic appeal and is the perfect complement to the engine‘s gutsy, usable performance.
Matching the engine‘s strength is a rigid steel frame, 43mm telescopic forks, rear monoshock with Pro-Link, large diameter disc brakes, 18 inch front and 17 inch rear aluminum wheels – with a fat, 200-section rear tire – for street-bike levels of handling, feedback and stability.
Styling & Equipment
It‘s wide – 810mm up front, 933mm measured across the mirrors – low, and long; with seat height of 650mm. Drawn from all the overtones and billions of bytes that shaped its creators‘ imagination, the manga and anime influences throughout the NM4 are obvious in every chiseled angle and evocative curve, especially from head on: its broad, angular ‗face‘ will never go unnoticed. Behind it, the rider sits enveloped in a cockpit-like surrounding, with the digital instrument panel always in view.
Lighting is full LED with front indicators and mirrors integrated into the bodywork while the stylized headlight is framed with a distinct LED definition line. Everything is blacked-out to the max – with carefully-placed glimpses of burnished stainless steel here and there – and only one paint option will be available—matt black.
The obvious question every NM4 rider will face is ―what film was THAT in‖? Its looks are that bold. And as a machine that comes straight from the rapidly beating heart of Japanese manga culture, it was always going to be different. Having absorbed its striking presence, the thought that‘s gone into the design becomes more apparent.
Storage spaces abound, concealed in the front bodywork. The lockable left compartment opens with the ignition key and features 1-litre of storage space plus a 12V DC adaptor to recharge what matters while on the move. The right compartment has 3-litres of storage and opens with a push of a recessed, triangulated button. Rear panniers integrate fluidly adding even more convenient carrying capacity.
And in one of those ―how come this hasn‘t been done on a motorcycle before…?‖ moments, the rear passenger seat flips upright when not in use, locking to provide the rider with a secure backrest and almost fighter pilot riding position. Its angle can be adjusted through 3 positions and it slides back/forward 25mm through four settings, to fine-tune cockpit comfort.
The digital dash changes mood depending on the drive mode selected, with subtle colour changes from Neutral (white) through D (blue) to S (pink), ultimately to MT (red). Alternatively, the rider can choose one colour from five other tonal ranges of colour – 25 individual colours altogether – they want to live with on a day-to-day basis.
Dual Clutch Transmission (DCT)
In keeping with its avant-garde appeal, the NM4 comes standard with Honda‘s unique DCT, specially tuned for a smooth acceleration feeling.
DCT delivers consistent, seamless gear changes, and very quickly becomes second nature in use. It uses two clutches: one for start-up and 1st, 3rd and 5th gears: the other for 2nd, 4th and 6th, with the main shaft for each clutch located inside the other for compact packaging. Each clutch is independently controlled by its own electro-hydraulic circuit. When a gear change occurs, the system pre-selects the target gear using the clutch not currently in use. The first clutch is then electronically disengaged as, simultaneously, the second clutch engages. The result is a consistent, fast and seamless gear change. Furthermore, as the twin clutches transfer drive from one gear to the next with minimal interruption of the drive to the rear wheel, any gear change shock and pitching of the machine is minimized, making the change feel direct as well as smooth.
With extra benefits such as durability (as the gears cannot be damaged by missing a gear) impossibility of stalling, low stress urban riding and reduced rider fatigue, DCT‘s acceptance and popularity is fast expanding in global markets.
Three modes of operation are available. MT mode gives full manual control, allowing the rider to shift with the handlebar trigger control buttons. Automatic D mode is ideal for city and highway riding, and achieves optimum fuel efficiency. Automatic S mode is sportier and the ECU lets the engine rev a little higher before shifting up, giving greater performance. It also shifts down sooner when decelerating for extra engine braking.
In either D or S mode, DCT offers immediate manual intervention if required – the rider simply selects the required gear using the up and down shift triggers on the left handlebar. At an appropriate time DCT seamlessly reverts back to automatic mode, depending on throttle angle, vehicle speed and gear position.
Furthermore, in D mode, the DCT system detects variations in rider input typical to certain environments, from busy urban streets to mountain switchbacks, and adapts its gear change schedule accordingly to create an extra level of riding compatibility. ―Kickdown‖ gear changes are natural and intuitive.
The compact liquid-cooled, SOHC 8-valve parallel twin-cylinder engine driving the NM4 is a usable, fuel-efficient and clean powerplant. The fundamental design ensures a punchy low-to-mid range performance: relatively long-stroke architecture and specially shaped combustion chambers combine with the high-inertial mass crankshaft to produce large amounts of effortless torque from very low down in the rev range.
Bore is set at 77mm with 80mm stroke, plus compression ratio of 10.7:1. The engine features twin balance shafts, the effect of which counteracts vibration from high rpm inertia. So it manages to feel refined, yet retain the characterful ‗throb‘ delivered by its 270° firing order. Where possible, components are made to do more than one job: the camshaft drives the water pump, while one of the balancer shafts drives the oil pump.
There‘s a single 36mm throttle body and PGM-FI fuel injection system supplies the optimum amount of fuel/air mixture thanks to an oxygen sensor in the exhaust. A high-absorption catalyzer is located close to the engine – as a result the catalyst reaches operating temperature quickly after a cold start, further reducing emissions. As with other models using similar engine technology we are expecting that the fuel consumption will be particularly impressive.
The rugged steel diamond frame at the NM4 core delivers high levels of rigidity required for agile, responsive handling in a variety of conditions from busy urban to open road. Rake is set at 33° with trail of 110mm, wheelbase of 1,645mm and front/rear weight balance of 49/51. The curb weight is 245kg.
The 43mm telescopic forks feature 125mm of stroke. The rear monoshock has 100mm of travel and operates through Pro-Link for a soft initial stroke. The lightweight aluminum swingarm improves suspension reaction and control.
The front 320mm wavy disc and two-piston brake caliper offer plenty of easy to modulate stopping power, matched by the rear 240mm wavy disc and single-piston caliper. Two-channel ABS helps greatly reduce the chance of wheel lock-ups on slippery or wet road surfaces.
A Unique 10-spoke cast aluminum front and rear wheels – sizes 18 x 3.50-inch front and 17 x 6.25 inch rear – finished in black and wear 120/70 ZR18 and 200/50 ZR17 tires.
