1. Introduction

The Forza 125 is designed for those European customers who demand more from a 125cc scooter: more performance, more agility and more usability. They are motivated by style, quality and performance; they expect a lot out of life and aim to extract the most from every experience.

The machine they ride has to offer the very maximum a 125cc scooter can give, and look good while it does it. And it has to combine the best of two worlds: the highway ability and comfort of larger capacity ‘GT’ style (Grand Touring) scooters and the traffic-beating, sporty acceleration and easy-to-park utility of smaller, lighter machines.

Honda’s Forza 125 does just that, creating a compelling proposition for those that want the very best that a 125cc scooter can offer.

Mr. T. Suda, Large Project Leader Forza 125:

The team’s aim with the Forza 125 was to make the ultimate 125cc scooter, with the very best of everything. It offers both great highway performance for a fun, easy commute, and class-leading acceleration for the city. All with classy, premium styling, and a very strong focus on practicality and comfort.


2. Model Overview

The Forza 125’s slim exterior exudes an aggressive, sporting attitude and a dynamic, modern design and layout. Inviting ergonomics offer a perfect fit for both rider and pillion while the windshield is height adjustable to suit both highway and city riding. There’s plenty of storage room (48 litres - enough for two full-face helmets) beneath the seat plus a 12V power socket in the glove box and – underlining its premium credentials – LED headlight, position lights, taillight and license plate light.

The 125cc liquid-cooled engine is a four-valve unit with an intake and exhaust system designed for strong mid-range and top end power. It offers swift pick-up from standstill, class-leading rolling acceleration from 90km/h and strong high speed performance. A host of low-friction technologies mean that this is combined with impressive fuel economy of 43.5km/l (WMTC mode). For 2017, the engine also now meets the stringent EURO4 emission regulations. The allowable limits for exhaust tailpipe pollutants such as carbon monoxide, hyrdrocarbons and nitrous oxide specified by EURO4 are approximately half of those for EURO3.

To deftly manage city streets and cruise open highways, the steel frame – with carefully optimised wheelbase and steering geometry – employs supple 33mm telescopic forks and twin rear shock absorbers. A 15-inch front wheel provides stability and confidence, backed up by the 14-inch rear. Large diameter single discs front and rear come with the option of ABS.

The Forza 125 is the best-selling premium 125 scooter in Europe in 2016. For the 2017 model, the formula has been even further enhanced with the addition of Honda Smart Key technology, revised rear suspension, new Michelin tyres and 3 new colours.

A range of purpose-built accessories is ready to tailor the Forza 125 perfectly to its owner’s lifestyle and includes heated grips, rear carrier and 35L colour-matched top box.


3. Key Features

3.1 Styling & Equipment

Easy mobility underpins the Forza 125’s look and functionality – it’s a contemporary design enabling life in and out of the city. The exterior’s trapezoidal proportions highlight the original ‘forward mass balance and performance strength’ concept of the styling team, and give the rider protection from wind while presenting a light and sporty appearance.

The sit-in riding position cups the rider securely and the screen easily adjusts through six positions and a total of 120mm for use at higher speeds and city traffic, to suit all types of riders. There is plenty of room for two adults on the carefully profiled seat, which opens to reveal storage space to match: two full-face helmets fit beneath it. The glove box up front contains a 12V socket for charging electrical accessories on the go and also easily holds a plastic water bottle. Seat height is a comfortable 780mm.

Premium LED technology has been adopted; underscoring the dual LED headlights are LED position lights that lend a crisp edge and unique identity to the Forza 125 ‘s frontal signature. Indicators are mounted high in the mirror bodies - which have been repositioned for 2017 for improved visibility - and stereoscopic LED taillights are matched by LED number plate illumination.

The stereoscopic theme extends to the instruments. Mounted high for ease of viewing and lit with a reverse LCD display and deep colour tone, the speedo and rev-counter are defined by elegantly flowing curves. A central LCD block features a clock (with large display), fuel gauge, average fuel economy meter, section fuel economy meter, A & B trip meters, odometer and coolant temperature.

For 2017, the Forza 125 is fitted with the Honda Smart Key system. The ‘key’ itself 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.


The Forza 125 will be available in five colour options for 2017, three of which are new:

Matt Cynos Grey Metallic/Black

Matt Pearl Cool White with Matt Pearl Pacific Blue

Black Matt Ruthenium/Silver Metallic (new colour)

Matt Cynos Gray Metallic/Matt Pearl Havana Brown (new colour)

Lucent Silver Metallic/Matt Pearl Pacific Blue (new colour)


3.2 Chassis

The steel frame that’s the focus of the Forza 125’s chassis provides the necessary rigidity and strength for the mix of riding conditions it will face. Sturdy 33mm telescopic forks are matched by twin rear shock absorbers – adjustable through 7-stage spring preload – working through a 1-piece aluminium swingarm. For 2017, the rear suspension has been further improved, with a more progressive damping feel.

The light weight of 158kg (159kg for ABS version) not only aids performance but also makes the Forza 125 easy to manage at walking speeds, and easy to park. The dynamics of the chassis ensure composure on the highway and agility in traffic. A wheelbase of 1,490mm provides stability; the steering geometry – 26.5° rake and 89mm trail – delivers nimble steering.

The cast aluminium 15-inch front wheel is fitted with a 120/70-15 tyre while the 14-inch rear uses a 140/70-14, offering maximum traction and ride comfort. For 2017, the popular Michelin City Grip tyres offer outstanding grip and feel in any weather conditions. A large 256mm single disc performs stopping duties up front, mated to a 240mm rear – both have the benefit of optional ABS for extra braking control on slippery surfaces.


3.3 Engine

The Forza 125’s new four-valve water-cooled SOHC powerplant delivers 11kW@ 8,750rpm, with peak torque of 12.5Nm @ 8,250rpm. Bore and stroke is set at 52.4 x 57.9mm; compression ratio is 11.5:1. From a standing start it accelerates rapidly, while sharper mid-range makes for reactive roll-on performance in the typical 40-60km/h around-town speed range. At speeds over 90km/h its top-end strength delivers class-leading acceleration, and for 2017, a higher gearing ratio gives the Forza 125 even more highway performance.

The engine is packed with Honda’s eSP low-friction technologies; clever packaging of items like the oil pump (which is built in to the crankcase) help to further ensure efficiency. A compact combustion chamber and PGM-FI fuel injection – fed by a redesigned 4.7-litre airbox and 28mm diameter inlet duct – optimise burning velocity and cooling performance. A new triple chamber exhaust muffler contains a 400-cell catalyser to clean up exhaust gases.

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 compact 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 by the use of three low-friction main bearings, all designed to deal with the loads they individually receive. The drive pulley features a fin design that lowers air resistance and the follower pulley reduces pressure on the drive belt, cutting transmission losses.

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, and re-starts it instantly the throttle grip 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. The battery is a long-life YTZ8V unit.

One of the aims of the development team working on the Forza 125 is that the trip to the fuel station should happen just once a week for the average user; accordingly, a 500km tank range has been achieved thanks to the 11.5 litre tank the engine’s fuel efficiency of approximately 43.5km/l (WMTC mode), which remains the same for 2017 even with EURO4 compliance.
