Designed to be light, compact, extremely stingy on fuel and to conserve resources during manufacturing, the liquid-cooled, inline-twin engine incorporates numerous advanced and patented technologies.
To ensure strong acceleration, ease-of-use in the city and a relaxed character on the highway, the engine delivers exceptionally strong low-rpm performance. The unique design creates a muscular, easy-to-use powerband.
To give the engine a satisfying and distinctive sound and feel, engineers thought way outside the box. Twin balance shafts counteract vibration from higher rpm inertia, making the engine feel more refined, yet still with the distinct “throb” delivered by its 270° firing order. The intake-port layout was carefully designed to create an intentional interference between adjacent ports, resulting in subtle combustion variations. In addition, the timing for the opening and closing of the intake valves was set differently for each cylinder. The result? An engine that connects with the senses.
The engine’s inline cylinders are canted forward to help create a low overall centre of gravity for nimble, confidence-inspiring handling.
Through the use of friction-reducing technologies, integrated components (such as running the water pump off the camshaft), precise PGM-FI electronic fuel-injection and efficient combustion, the NM4 engine delivers exceptional fuel economy.
The engine’s efficient use of fuel enables the use of a smaller-volume, more-compact fuel tank that still allows ample riding range while giving engineers extra freedom to re-think the optimal placement of other components.
The exhaust catalytic converter sits directly beneath the exhaust ports and is activated early when the engine starts. This design lets the combustion gas pass through the catalyst while it is at its hottest, thereby maximizing purification efficiency.
The Dual Clutch Transmission (DCT) includes two automatic drive modes, normal (D) and sport (S), as well as a manual mode with trigger-style shifting. Offering consistent, fast and seamless gear changes the twin clutches transfer drive from one gear to the next with minimal interruption, reducing gear change shock and pitching of the machine. Gear changes feel direct and smooth.
The lightweight, diamond-shaped steel-tube frame was carefully designed to be very sturdy while also allowing just enough flexibility to respond smoothly to changing road surfaces. This “tuned flexibility” produces a smooth ride while also generating a strong feel for what the bike is doing.
Low seat height of only 650 mm and well placed floorboards put the rider firmly in control, with handlebars just a relaxed reach away. The high leverage handlebars and super-low centre-of-gravity further increase rider confidence.
Honda’s two-channel ABS (Anti-lock Braking System) provides added confidence during sudden stops or when the road is wet or slippery.
Lightweight aluminum swingarm improves suspension reaction and control.

The digital dash changes mood depending on the drive mode selected, with subtle colour changes from grey in Neutral, to light blue in D, to vibrant pink in S, ultimately to aggressive red in manual mode. The rider can also choose between five other tonal ranges of colour – 25 individual colours altogether to personalize their dash.
The rear pillion seat flips upright when not in use, locking to provide the rider with a secure backrest and an almost fighter-pilot riding position. Its angle can be adjusted through three positions and it slides back/forward 25 mm through four settings, to fine-tune cockpit comfort.
Convenient storage spaces are concealed in the front bodywork. The left compartment opens with the ignition key and features 1-litre of storage space plus a 12V DC adaptor to recharge personal electronics. The right compartment has 3-litres of storage and opens with the push of a recessed, triangulated button.
Matte black paint and componentry is complemented by carefully placed glimpses of burnished aluminum.
