1. Introduction
An entry-level 125cc motorcycle has to be a multi-faceted machine. To some it represents
the most economical way of getting from A to B, both in terms of initial affordability and
running costs. To these riders it must be durable, easy to live with and economical: simple,
trouble-free transport at its most fundamental.
But to many new riders a 125 is the start of their motorcycling adventure, their first ‘real’ bike.
So it must deliver all of the above and everything else that a motorcycle should - the
excitement, freedom and instinctive pleasure that two wheels bring to everyday life. Yet it
also has to inspire confidence, be easy to ride and instill pride of ownership with style that
adds street credibility.
For any manufacturer, welcoming and introducing fresh entrants to their brand is important.
The right initial experience can lead to a lifelong association, especially when a family
progression is built into the line-up for when age and experience advance.
Honda’s CBF125 has long proved a tough, user-friendly entry-level motorcycle. The new
2015 CB125F is drawn from a fresh gene pool and while it maintains the previous model’s
core strengths, it builds heavily on quality, ease of use and a desirable new look. It’s a great
bike to simply get you where you need to be – or from where to begin the ride of a lifetime.
2. Model Overview
The new CB125F has been styled with a strong family resemblance to the twin-cylinder
CB500F and four-cylinder CB650F. An injection of aggressive ‘streetfighter’ attitude matches
an upright riding position and wide handlebars, giving excellent control.
An all-new steel frame provides strength, with geometry for all-round reactive and confident
handling. Revised 18-inch (from 17-inch) wheels iron out surface imperfections and aid
stability, as do the telescopic forks and twin rear shocks. Powerful but novice-friendly braking
is delivered by a hydraulic caliper and disc up front with a drum rear.

2. Heart and soul of the new CB125F is its robust fuel-injected single-cylinder engine. The
engine has been developed to deliver strong low and mid-range torque with crisp throttle
response. It provides brisk acceleration in busy urban situations, is easy to manage and
smooth at all rpm thanks to the addition of a balancer shaft. It’s also economical and a ready
starter in challenging weather conditions thanks to use of the latest design PGM-FI system.
For the end user the other good news is that the 2015 CB125F, armed with an array of
improvements plus Honda engineering and high quality finish arrives in dealers at a highly
competitive price point.
3. Key Features
3.1 Styling & Chassis
With strong desire for naked motorcycles of all capacities throughout Europe, the CB125F
channels its larger siblings’ street style with a broad-shouldered and muscular ‘mass
forward’ stance. Angular side shrouds extend forward from the fuel tank and the contoured
side cowls narrow neatly, minimizing the height difference between rider and pillion.
The compact nose cowl surrounding the multi reflector headlight and dash display completes
the aggressive new look. Clear indicator lenses and orange bulbs add a stylish finishing
touch.
The engine, exhaust downpipe and muffler, fork lowers and wheels are blacked out,
underlining the crisp lines and bright paintwork. Subtle red detailing is to be found on the
shock springs and Honda logo on the engine crankcases. It’s a bike built to endure the
rigours of European weather, whilst its new style, build quality and finish add greatly to
owner satisfaction.
As a machine that will see use as every day commuter, riding school stalwart and open door
to the world of motorcycling, its riding position is upright and relaxed, with more forward-set
footpegs and wide handlebars (pulled back slightly, with 45° lock left and right) giving
optimum control, rider confidence and all-round visibility. Seat height is 775mm.
The integrated steel frame suspends the engine from a sturdy central spine and features
geometry that provides the best balance between ride comfort and straight line stability, with
a focus toward light steering input and sporty feel at all lean angles. Rake and trail are set at
26° and 97mm with wheelbase of 1295mm. Kerb weight is just 128kg.
Dual rear shocks offer 5-step spring preload adjustment and complement the 120mm
telescopic fork’s compliance and ride quality; stylish six-spoke 18-inch aluminium front and
rear wheels increase stability and ride quality over rough city streets. Tyres are sized 80/100
front and 90/90 rear. A 240mm front disc is worked by a double piston caliper, with back up
from the 130mm rear drum.
The CB125F will be available in three colour ways:
Pearl Twinkle Yellow
Onyx Blue Metallic
Candy Blazing Red

3. 3.2 Engine
The CB125F’s 124.7cc, air-cooled fuel-injected OHC 2-valve engine is tough, proven and
efficient. Bore and stroke is set at 52.4 x 57.8mm, with compression ratio of 9.2:1. The
cylinder head has been revised for 2015 and the addition of a balancer shaft neutralises
vibration. The 5-speed gearbox provides a wide spread of useful ratios. Peak power of
7.8kW arrives at 7,750rpm, with maximum torque of 10.2Nm delivered at 6,250rpm.
But numbers tell only half of the story; focus of the engineering team was around the
powerplant’s real-world user friendliness – in other words, strong low and mid-range torque,
with excellent throttle response for smart acceleration from a standstill in urban riding. The
engine’s pick up and throttle response is noticeably stronger.
Fuel economy of 120.7mpg (WMTC mode) provides a range of over 370 miles between fill-ups
from the 13-litre tank and the PGM-FI employs the latest solenoid, making for much
easier starting in extreme cold or adverse weather.
