  1. Introduction

The Forza name has long been a powerful force in Honda’s two-wheeled line-up. Its history as a premium, mid-size scooter goes back to the year 2000: the first model set the template, delivering a lively ride, plenty of storage room and an innovative combined braking system. It was well received throughout Europe, where owners found its multi-role capability useful in every aspect of daily life.

While retaining its trademark mix of sporty and GT character, the Forza 300 has constantly evolved, aiming to exceed owners’ expectations with every upgrade. In 04YM it gained Honda’s S MATIC electronically controlled CVT (Continuously Variable Transmission), a theft-deterring Smart key, highly efficient PGM-FI fuel injection for the engine and space for two full-face helmets under the seat.

05YM saw the addition of ABS brakes and, in 08YM, luxurious touches like an audio package and speakers plus upgraded S MATIC (with phased auto shift mode) and Combined ABS brakes were added. In 16YM it moved on again, as the Forza 300 with a new ‘sit-in’ design large enough to carry two people in total comfort, even at highways speeds.

18YM marked the unveiling of a radically revised Forza 300 – lighter, smaller, sharper and sportier – following in the hugely successful wheel tracks of its little sibling, the Forza 125, while retaining all the best attributes of its ‘GT’ nature. A ‘Limited-Edition’ model with Grey/Gloss Black colour scheme and matching Smart top box added an exclusive choice in 2020.

In 21YM it was time for another advance – the Forza 350. Faster, even more useful – with new features like Bluetooth connectivity and Honda Smartphone Voice Control system – and, of course, stylishly desirable with it.

Mechanically unchanged for 22YM, a premium new colour option adds further appeal.

  1. Model Overview

Developing 21.6kW and 31.9Nm, the Forza 350’s 330cc engine is strong all the way through its rev-range, delivering crisp acceleration and a top speed of 137km/h. It’s also EURO5 compliant.

Alongside the new engine, in 21YM, cosmetic and aerodynamic updates were applied to the front fairing sides, mirrors, rear side panels and engine cover for a sleeker overall look with even more premium appeal. The chassis was unchanged but connected to a lighter swingarm, and the adjustable electric screen gained an extra 40mm travel to improve wind protection.

The instrument panel was also refreshed, with the Forza 350 rider having the possibility of linking to their smartphone via Bluetooth via the Honda Smartphone Voice Control system which is available as an option from new.

A USB Type-C socket provides convenient charging, with room for two full-face helmets in the under seat storage compartment.

The 22YM Forza 350 will be available in the following colour options:

Mat Carnelian Red Metallic **NEW**

Mat Pearl Pacific Blue

Pearl Cool White

Matt Cynos Gray Metallic

Pearl Falcon Gray

  1. Key Features

3.1 Styling & Equipment

  • Electric screen adjusts through 180mm
  • Room for two full-face helmets under the seat; USB charging socket
  • Smart Key operation of ignition and (optional) 45-litre top box
  • Emergency stop signal function (ESS) warns other road users of sudden braking

The Forza 350’s lines flow back from its electric screen (controlled by a switch on the left handlebar) which adjusts through 180mm. It’s designed to provide wind protection, with airflow directed around and over the rider’s head, and reduce wind noise. Stability and comfort at higher speeds – and long distances – can be instantly exchanged for a greater sense of freedom around town, by lowering the screen. For comfort at higher speeds a larger front air duct manages negative pressure in front of the rider, reducing the natural effect of the wind pushing the rider back.

Sculpted for both style and aerodynamic efficiency, the Forza 350’s sharp design lines give a clean, smooth modernity, creating an impression of energetic sportiness and premium desirability. The styling team’s key words of ‘aggressive, technical and powerful’ find expression in a new spoiler-type surround below the headlight, refreshed fairing side panels with a distinctive ‘Z’ design line, and a steeply descending character line for the rear side panels that create a forward-looking, purposeful aesthetic.

Two full-face helmets can be stored under the seat, and it’s also possible to partition the storage area to house a helmet and/or rain gear and A4 sized bags. The front left inner fairing pocket is lockable, and its internal space can be arranged for the rider’s convenience, to hold a phone and water bottle, for instance. It also houses a USB socket. All lighting is premium LED.

Keeping its rider fully connected, the Forza 350 also has the Honda Smartphone Voice Control system available as an option from new, which links the rider to their smartphone while on the move and allows voice management of phone calls and music. A helmet-mounted headset is needed and the smartphone connects via Bluetooth; management of Honda Smartphone Voice Control System is from the left switchgear and dash.

The Forza 350’s Smart Key – as well as controlling the main ignition switch knob and compartment locking – also manages the optional 45L Smart top box. With the Smart Key in the rider’s pocket the box is unlocked, and automatically locks when the rider walks away. It can also be locked from the key. To maintain the internal volume of the box the actuator mechanism is located in the rear body of the machine.

The front and rear indicators of the Forza 350 have an auto-cancelling Emergency Stop Signal feature. Once the ABS modulator detects sudden braking, the rear indicators flash at high speed to warn other vehicles.

Instruments present analogue speedometer and rev-counter flanking a digital display that can switch between 3 modes: 1) odometer, range remaining and current mpg, 2) trip meter, average mpg and timer and 3) ambient temperature thermometer and battery sensor.

3.2 Engine

  • 330cc engine puts out 21.6Kw peak power with 31.9Nm torque
  • enhanced Smart Power+ (eSP+) technology ensures fuel economy of 30km/l (WMTC mode)
  • EURO5 compliance

The Forza 350’s eSP+ engine achieves both high environmental performance and strong output characteristic through comprehensive adoption of technologies for friction reduction.

Liquid-cooled the 330cc, fuel-injected SOHC four-valve unit produces peak power of 21.6kW @ 7,500rpm, with maximum torque of 31.9Nm @ 5,250rpm. Top speed is 137km/h and, from a standing start, the Forza 350 will cover 200m in 10.4s.

Bore is set at 77mm with stroke of 70.7mm; compression ratio is set at 10.5:1. Roller-type rocker arm, plain journal crank bearings and sealed crankcases deliver long-term reliability together with strong performance. To enhance piston cooling, an oil jet, as used on the CRF450R, sprays oil right to the back of the piston, advancing ignition timing and improving combustion performance. Oil capacity is 1.8 litres.

Air is supplied via a 5.5 litre airbox which feeds a 36mm throttle body. The intake port draws air efficiently, utilising a ‘tumble’ flow within the cylinder for more consistent fuel combustion. Exhaust gases are expelled via a straight exhaust port and, to reduce exhaust gas resistance, the muffler consists of two distinct chambers.

Internal friction is reduced through a 5mm offset cylinder, a hydraulic cam chain adjuster and the use of a scavenger pump. Used on high performance machines, the pump lowers the internal pressure within the engine, reduces oil agitation and decreases pumping losses and internal rotational friction. A balancer shaft further reduces vibration and contributes to a smooth enjoyable ride.

An automatic centrifugal clutch works a V-Matic transmission (with ratios set for fast low speed reaction and smart acceleration) and belt final drive.

The Forza 350’s engine is equipped with Honda Selectable Torque Control (HSTC). The system detects any difference between the front and rear wheel speeds, calculates the slip ratio and then controls engine torque via the fuel injection to regain rear wheel traction. HSTC can be switched ON-OFF via a switch on the left handlebar. A ‘T’ indicator in the digital display flickers when the system is working to manage grip.

The engine is homologated for EURO5, which from January 1st 2020 introduced significantly stricter engine emissions standards compared to EURO4. These requirements include substantial reductions in permitted carbon monoxide emissions, an over 40% decrease in total hydrocarbon emissions, tougher misfire detection and the introduction of a particulate matter limit.

Fuel economy is a frugal 30km/l (WMTC mode); the 11.5L tank capacity gives a potential 340km+ range.

3.3 Chassis

  • Short wheelbase with sharp steering geometry
  • Compact body dimensions paired with a practical seat height
  • Both wheels cast aluminium; 14-inch diameter rear and 15-inch front

A sturdy, yet lightweight, tubular steel frame is at the heart of the Forza 350’s reassuring feel on the road. Wheelbase is 1510mm, rake is 26.5° and trail 89mm. The radiator is located in front of the fuel tank for better cooling performance, and the battery is found between the fuel tank and the under-seat storage area, focusing mass to the centre. Wet weight is 184kg.

Seat height is 780mm and the riding position naturally upright, promoting excellent all-round visibility. Handlebar width is 754mm, with front width of 580mm and mirror width of 860mm; compact dimensions that make slipping through traffic-heavy streets easy.

Rigid 33mm telescopic forks are matched by twin rear shock absorbers – adjustable through 7-stage spring preload – working through 1-piece aluminium swingarm.

The cast aluminium 15-inch front wheel is fitted with a 120/70-15 tyre while the 14-inch rear wears a 140/70-14 tyre, offering maximum traction and ride comfort. A 256mm single disc performs stopping duties up front, mated to a 240mm rear, with the benefit of 2-channel ABS for braking control on slippery surfaces.
