    Model updates: The CB125F is extensively revised with CB-F family ‘naked’ style plus a responsive new chassis and six-spoke 18-inch wheels. Built for real-world usability, its new air-cooled engine delivers strong low to mid-range torque, and features a balance shaft and revised PGM-FI settings. Build quality is also enhanced, while purchase and ownership costs remain outstandingly attractive.

    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 be easy for a novice to manage as he/she learns, with build quality that instills tangible pride of ownership and 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.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 four colour ways:

    Pearl Twinkle Yellow
    Onyx Blue Metallic
    Pearl Sunbeam White
    Candy Blazing Red

    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 51.3km/l (WMTC mode) provides a range of over 600km 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.

    But.... but.....but.... it's less powerful than the current model - which I think looks better too, watch them ( >2014 ) hold their prices now.

    Yeah I know but Honda have shifted their motorcycling philosophy for road going bikes, they creating bike with more low end torque for the real world riding. Everything today is not about HP with fuel injection low down torque it will reward the novice rider more than sheer speed. The 70's and 80's was the era of silly power that is gone and we all know how many young riders lost their lives with poor brakes poor tyres and poor suspension.

    The fact people are still hanging on to the past is the best problem for motorcycling with the new licensing regime there are no long term younger riders today, youngsters are not taking to motorcycles like they used to. The average biker age today is 40 plus and it needs to change.

    Honda is right to change that perception.

    Low end torque and real world riding is okay with real motorcycles.
    My son bought a brand new 2013 CBF125 last year (with the little belly pan and fairing)
    I'm quite an experienced rider and believed there was something wrong with it when we initially made the purchase 'cos it was just too slow.
    I took it back to the dealer who tested it as all correct and stated that it was actually one of the 'faster' ones that they'd sold.
    Every young rider, (and me too), just to keep pace with traffic flow, will wring the neck out of any 125 that they're initially restricted to, 'cos they're so underpowered. And just like the 50cc moped legislation of the '70's (in which I was trapped and stuck with a Puch M50 Sports moped) prompts young riders to get rid of them as quickly as they can.
    Mind you, the year he owned that CBF125 for, it was managing 120+MPG every day.
    It was a looker in that guise, but not so much now with this 2015 revision.
    To me it's lost it's identity, too similar now to all the cheap Chinese copies knocking about.
    At 22 years old now, as an "A22 livence holder (for two years) he's running a Suzuki GS500F that I travelled to Essex to collect for him and is being forced to jump through hoops to get his full on '"A" licence.
    He's now down to about 80mpg but at least we were able to tour Scotland this last summer together with me leading the way on the 'Wing. Happy days.
    As to the '70's being the era of silly power.... have you seen the latest Kawasaki H2 and H2R...... now there's silly. (google it and see)
    - - - Updated - - -
    Whoops . meant to say......... "A 2" licence holder ....... above.... about 9th para down. sorry, no edit?

    Well first off all congrats your son taking up biking , feel sorry for him to sit so many test and and wait till his full A.. :nea:The problem you have today is no one barely keep to the speed limit, everyone on their best behaviour if a mobile speed camera van is out, so I can see you point of need the power to keep with flow. However the fact he has a underpowered bike he can adjust his riding skill by making that shortfall to his advantage by anticipating situation and control the throttle better . If you always have loads of power on hand then you will be racking up those speed tickets.. I learnt on the Yamaha RXS-100 2stroker it had power alight LOL , I installed a cheeky quick throttle on it. Get your son to install one and then see ooh we have power.

    Yes I have seen the Kawak H2 H2R very very good bike but Honda RCV for me.

    BTW are you going to the NEC show ? I have to get down to see these Hyper bikes use my drool as quick detailer.

    I still miss my MTX 125 it was loads of fun. I don't think the weedy 4stroke 125 of today is a good introduction to motorcycles.
    I worked for a motorcycle dealer in the 80's and had a race tuned Suzuki RG125. Now that felt more like a big bike. :Wink:
