Honda ADV 125

From a press release issued by Honda:

Bringing genuine ADV family DNA to the 125cc class, the ADV125 combines rugged SUV-inspired styling, sophisticated technology and everyday practicality with the efficiency and ease of use demanded by urban riders.

The ADV125 combines the proven efficiency and refinement of Honda's liquid-cooled enhanced Smart Power Plus (eSP+) engine with a chassis package specifically developed to deliver confidence and versatility regardless of the journey. Throw in chic, modern styling, a comprehensive specification and Honda’s renowned reliability and the ADV125 offers an appealing blend of style, practicality and technology for urban riders.

Built around a tall riding position and relaxed rider triangle, the ADV125 is as at home filtering through traffic as it is exploring beyond the city limits.

The long-travel suspension and generous 165mm ground clearance deliver both commanding visibility and the ability to tackle poor road surfaces with ease. Visually, the ADV125 embodies the modern sports utility vehicle approach that has defined its ADV350 and X-ADV stablemates. Wide block-pattern tyres contribute to comfort and stability while reinforcing the ADV125's unmistakable SUV-inspired appearance.

The ADV125’s appeal isn’t just cosmetic. Packed with an extensive spec list, the ADV125 features a full-colour five-inch TFT display, with Honda RoadSync smartphone connectivity, USB-C charging port, Smart key operation, as well as Honda Selectable Torque Control (HSTC) and in-built Emergency Stop Signals (ESS).

Everyday practicality remains central to the package. Under the seat sits a generous 29-litre storage compartment capable of accommodating a full-face helmet, while a front glovebox provides convenient stowage of small, everyday items.

The 27YM ADV125 will be available in the following colour options:
- Pearl Falcon Gray
- Pearl Cool White
- Mat Cynos Gray Metallic
- Mat Pearl Diaspro Red

Engine
- Proven, robust 125cc, water-cooled eSP+ SOHC four-valve engine
- Honda Selectable Torque Control (HSTC)
- Idling Stop technology

The ADV125 is powered by the same proven, robust powertrain as utilised by the PCX125. Built around the enhanced Smart Power Plus (eSP+) four-valve, water-cooled SOHC powerplant the ADV125 delivers 9.2kW @ 8,750rpm, with peak torque of 11.7Nm @ 6,500rpm. Bore and stroke is set at 53.5 x 55.5mm with compression ratio of 11.5:1.

It accelerates smartly from a standing start or roll-on, and the ADV125 will cruise happily around 90km/h. V-max is 97km/h. And, thanks to the engine’s fuel efficiency of approximately 47.6km/l (WMTC mode), and 8.1L tank range is approximately 385km between fill-ups.

Honda Selectable Torque Control (HSTC), which works in the background to deftly manage rear wheel traction, helps to boost rider confidence in wet conditions. A ‘T’ indicator flickers on the dash when HSTC is actively reducing wheelspin, and the system can be turned off completely.

Honda’s eSP+ low-friction technologies are found throughout the engine; clever packaging of items like the oil pump (which is built into the crankcase) help to further ensure efficiency. A compact combustion chamber and PGM-FI fuel injection – with 28mm diameter throttle body, 2mm larger – optimises burning velocity and cooling performance.

An offset cylinder reduces friction caused by contact between piston and bore, efficiently transmitting combustion energy to the crankshaft. A ‘spiny’ cast-iron sleeve – with tiny surface extensions – keeps in check any distortion of the inner bore diameter. This design lowers tension in the piston ring, reducing friction. A hydraulic cam chain tensioner further improves engine efficiencies by reducing internal vibrations and improving fuel economy.

Piston oil jets – as used by CRF450R competition MX machine – maintain consistent cooling. This allows ignition timing advances and prevents abnormal combustion, such as ‘knocking’. A hydraulic cam chain tensioner lifter inhibits chain vibration, controls noise and reduces friction.

A high-efficiency radiator – integrated into the exterior of the right-side crankcase – employs a small, light fan reducing frictional losses and lowering drag. Rolling resistance within the transmission unit is reduced using three low-friction main bearings, all designed to deal with the loads they individually receive. An optimised clutch – and pulleys – complement the performance.

The electronically controlled, brushless ACG starter is an integrated component mounted directly on the end of the crankshaft, serving as starter motor and alternator. It spins the engine directly, eliminating any noise from gear engagement or meshing.

Idling Stop automatically stops the engine running after three seconds at idle when the scooter is stationary, and the brakes applied, restarting instantly when the throttle is twisted. It’s seamless in use thanks to ACG and the swing-back system that returns the crank to its position before air intake, and a decompression mechanism that negates cranking resistance from compression. It has the functionality to ‘read’ the battery charge and turns itself off to avoid excessive drain.

Chassis
- Proven duplex steel cradle frame gives solid foundation for bike
- Long-travel suspension gives 165mm ground clearance
- Block-pattern tyres deliver confident handling and off-road ability
- Lightweight handling and excellent manoeuvrability

The ADV125 is built around a tough, duplex steel cradle frame that has been designed to deliver the durability needed for the rigours of everyday life, whilst delivering genuine rough-road capabilities.
Long-travel suspension delivers 116mm front and 103mm rear wheel travel, providing improved comfort when riding over potholes, poor road surfaces and urban obstacles. External reservoir rear shock absorbers add a new level of damping consistency, and reinforce the premium feel of the package.

The ADV125's distinctive wheel design complements its rugged styling while contributing to ride comfort and rider feedback. These are mounted with block-patterned tubeless tyres, which have been selected to cope with unexpected variation of city street surfaces, as well as deliver run-through performance on unpaved and rough roads. Sized 110/80-14 for the front and 130/70-13 for the rear, the tough-looking tyres contribute to the SUV aesthetic and deliver linear handling performance and pleasant ride comfort.
Braking performance comes from a 240mm front wavy disc and 220mm rear wavy disc. This new design not only reduces unsprung weight, but also effectively scrapes out dirt and rainwater on the pad ensuring consistent performance regardless of the road surface.

Styling & Equipment
- Five-inch TFT with RoadSync connectivity for everyday convenience
- Smart key operation of ignition and seat for effortless usability
- 29L underseat storage capacity and adjustable windscreen
- Upright riding position with optimised rider triangle focusing on rider comfort

The ADV125's styling is instantly recognisable as part of Honda's wider ADV family, combining sharp bodywork, strong horizontal lines and rugged proportions inspired by modern SUVs and adventure motorcycles. Its bold, confident shapes help create a unique silhouette in the 125cc scooter segment.
Wide block-pattern tyres, substantial suspension components and an elevated stance reinforce its tough, go-anywhere character, while careful attention to rider comfort and practicality ensures it remains perfectly suited to everyday use.

A key feature is the two-position windscreen, which can be adjusted through 75mm using Honda's slide-lock mechanism. In its lower setting it promotes airflow during urban commuting, while the higher position provides increased weather protection and comfort on longer journeys.

The upright riding position delivers excellent visibility in traffic and helps reduce fatigue over extended distances. A narrow seat profile and accessible 780mm seat height further enhance rider confidence, particularly at low speeds and when manoeuvring in confined spaces.

Practicality is enhanced by generous storage and convenience features, including 29 litres of under-seat luggage space, a 2-litre front inner box and a USB Type-C charging socket. Full LED lighting and Honda SMART Key operation add a premium feel, making the ADV125 as convenient as it is versatile.
Central to the riding experience is Honda’s proven five-inch TFT display that offers clear information presentation to riders and brings with it Honda RoadSync smartphone connectivity. The system allows riders to access selected smartphone functions, such as music control, navigation, messaging and more, while keeping their attention focused on the road ahead.

Honda SMART Key adds further everyday convenience, enabling keyless operation of the ignition, seat and fuel filler system while also incorporating anti-theft and answer-back functions.

Comprehensive safety comes via Honda Selectable Torque Control (HSTC), which is equipped as standard. The ADV125 is also equipped with Emergency Stop Signal technology, which automatically flashes the indicators under heavy braking to alert following road users to sudden deceleration.
