1. Introduction

Part of the million-selling SH family whose founding member, the SH50, went on sale in 1984 the four-stroke Honda SH150 (and SH125) first hit the market in Europe in 2001, with both models gaining fuel injection in 2005. Ever since both have quietly and consistently gone about their mission to provide stylish, fun and fuss-free transport – becoming true favourites along the way.

That first machine laid down the blueprint for success: a frugal-natured but lively engine that could deal with highway as well as town use tied to nimble, sure-footed handling underpinned by the stability that large diameter 16-inch wheels deliver – all wrapped in elegant, premium styling.

Over the last 20 years the SH150i and its 125cc sibling have come to represent the ultimate in urban transport with the perfect balance of style, reliability, economy and downright usability.

And of course, its story is one of constant, careful evolution reflecting the developing needs and expectations of owners, and Honda’s desire to keep on giving them an even better version of their SH. In 13YM it received Honda’s eSP (enhanced Smart Power) low friction engine and Idling Stop, boosting both power delivery and fuel economy. And in 2017 the look was refreshed with more chiselled design lines, and LED front/rear lights and Honda Smart Key added.

In 20YM the SH150i, manufactured at Honda’s Atessa factory in Italy, and immensely popular in the Italian market due to legislation that prohibits 125cc machines from motorways was, effectively, a brand-new scooter. Standing squarely on the shoulders of its forbears it instantly became faster, even more stylish, comfortable, convenient to use and as cost effective as ever to own and run. 24YM saw the arrival of the SH150i Vetro, a unique bike is the brainchild – and a tribute to the technical skills – of the workforce at Honda’s factory in Atessa, Italy. The model variant made its debut last year with its distinctive semi-transparent, unpainted fairing panels – production of which produces 9.5% fewer CO2 emissions over a year compared to those of the standard colouring schemes. 

For 26YM, the SH150i moves forward once again with style and functionality updates cementing its position as a surefire choice.

‘The King of European Commuters’

2. Model Overview

The SH150i is built for life and features refreshed styling, with plenty of ever-useful storage space plus a USB-C socket now housed in the new glovebox. Seat material has been optimised for increased ride comfort while SH-signature 16-inch wheels roll smoothly. Refined styling is all-new for 26YM, with a stylish riff on the classic silhouette – led by redesigned LED lighting, whilst the new 4.2-inch TFT display, with Honda RoadSync smartphone connectivity is a premium finishing touch.

The EURO5+ compliant four-valve eSP+ engine produces 12.4kW peak power, 14.9Nm torque, returns 44.7km/l (WMTC mode) and features Idling Stop technology. HSTC (Honda Selectable Torque Control) to manage rear wheel traction is also a bonus for an owner’s peace of mind.

3. Key Features
    3.1 Styling & Equipment

• Restyled front mask introduces a new elegant style, whilst revised side panels create a unified, sleek silhouette
• Premium LED lighting all-round
• Premium tech in new 4.2” colour TFT screen with Honda RoadSync connectivity and smart key operation

The SH350i heads the SH family and, for 26YM, the SH150i follows its strong 25YM style refresh. With an elegant presence and luxurious feel the sophisticated ‘front mask’ sets it apart, and the update brings with it a redesigned LED headlight – with central main beam splitting dual dip beams – while revised panels, side lights and reprofiled indicators create a sleek, contemporary frontal signature. The LED taillight and indicators sit neatly at the rear, between an aluminium grab rail.

And, in true SH fashion, classy looks are matched to effortless practicality. The overall compactness, flat floor and upright riding position (essential for ease-of-use and visibility in busy town traffic) are conspicuous hallmarks. Less obvious is the 28L of under seat storage, capable of holding a full-face helmet. Conveniently, the USB-C socket moves from under the seat and is now sited in a new inner front fairing inner glove box, handily sized at 175.5 x 88 x 11.9mm.

The flat seat, employing a new urethane material for plusher comfort, provides plenty of support and room to move around. its carefully contoured shape, plus slim floor width, makes reaching the ground easy. As many journeys around town involve a pillion there’s plenty of room for two; retractable aluminium pillion footplates tuck away when not in use.

A revised 4.2-inch TFT screen integrates into the handlebar cover and offers simple, crisp information delivery as well as the usefulness – especially for on-screen navigation – of Honda RoadSync smartphone connectivity. Also, smoothing day-to-day riding, the Smart Key resides in the rider’s pocket and does away with the need to constantly insert and withdraw a key for ignition, fuel cap and seat. It has two switches: the smart function on/off and ‘answer back’, which flickers the indicators for identification from a distance.

With the Smart Key present one push of the machine-mounted main switch powers it up and makes it possible to turn, giving the rider control of the ignition and steering lock, and, via two rocker switches, the fuel cap and seat. It also illuminates when pushed, or from the answer back function of the Smart Key, with a blue light.

3.2 Engine

• Four-valve eSP+ engine produces 12.4kW peak power and 14.9Nm torque
• Fuel economy of 44.7km/l (WMTC mode)
• Honda Selectable Torque Control (HSTC) standard
• Equipped with Idling Stop and low-friction technologies
• EURO5+ compliant 

The SH150i’s lively 157cc liquid-cooled four-valve enhanced Smart Power+ (eSP+) engine produces peak power of 12.4kW 8,500rpm with 14.9Nm torque delivered at 6,500rpm, and is the first Honda engine to meeting the stronger EURO5+ emissions regulations.

Technology to boost rider confidence in wet conditions is Honda Selectable Torque Control (HSTC), that works in the background to deftly manage rear wheel traction. An indicator flashes on the dash when HSTC is actively reducing wheelspin and the system can also be turned off completely.

Bore is set at 60mm with stroke of 55.5mm; compression ratio is 12.0:1. The compact engine is a masterpiece of mass centralisation. The radiator, rather than being mounted at the front of the machine is built into the engine itself for a simple, light layout. Its highly efficient core allows for the use of an ultra-compact, light cooling fan.

Low-friction technologies are employed internally; the cylinder sleeve uses minute splines on its outer surface to keep oil consumption low and improve cooling and the cylinder is offset to keep frictional losses to a minimum. Rolling resistance within the transmission is kept in check by using three main bearings, all designed to deal with the loads they each individually receive. The result of all these measures is an outstanding fuel economy (without Idling Stop activated) of 44.7km/l (WMTC mode).

Another key fuel-saving technology incorporated into the SH150i is Idling Stop. It’s operated via a switch on the right handlebar and, when enabled, automatically stops the engine running after three seconds at idle and re-starts it instantly when the throttle grip is twisted.

It is seamless in use, thanks to a swing-back system that returns the crank to its position before air intake, and a decompression mechanism that negates cranking resistance due to compression. The ACG starter also generates electricity, doing away with a conventional system’s motor and gears.

3.3 Chassis

• High-tensile tubular steel underbone frame 
• 16-inch front and rear wheels deliver sure-footed confidence
• Michelin City Grip 2 tubeless tyres 

The high-tensile tubular steel underbone frame sites the 7L fuel tank under the floor beneath the rider’s feet, which frees up space. Wheelbase is set at 1,350mm with rake and trail of 26°/85mm and turning radius of 2.0m. Seat height is 799mm with wet weight of 138kg.

For ride comfort the engine hanger link angle and rear suspension angle are optimised to reduce rotational load toward the engine link, making for supple bump absorption and control. The rear shocks feature 5-step preload adjustment and 85mm axle travel. For 26YM, the SH150i gains new rear springs with revised diameters and settings.

The 33mm telescopic front forks, with 90mm of travel, ensure excellent road holding and are tuned to match the new rear setup to give a compliant, yet controlled ride.

Lightweight 16-inch aluminium die-cast wheels have always been key to the SH150i’s sure-footed handling ability and stability on a variety of road surfaces and mount Michelin City Grip 2 tubeless tyres sized 100/80-16 front and 120/80-16 rear. ABS is fitted as standard; both front and rear discs employ a 240mm diameter; the front caliper is a two-piston design, the rear a single.
