These days in 150cc full fairing motorcycle segment Suzuki Gixxer SF vs Yamaha Fazer Fi competing hard on our roads. I such situation our riders are also in confusion in terms of buying. Consequently we are herewith Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Comparison Review.

suzuki gixxer sf vs yamaha fazer fi

Suzuki Gixxer SF Overview

Suzuki first brought the Gixxer in the market in year 2014, the bike was so successful that they thought to bring a new variant of the same motorcycle and they did, it was named Gixxer SF, SF stands for “Sports Fairing”. Gixxer SF shares same aesthetics as the Gixxer from flesh to bones. Full fairing of the Suzuki Gixxer SF gives it a very sporty look and makes it more aero dynamic.

This full faired motorcycles are loved by the young crowd mostly. Thinking of a fully faired motorcycle the names which comes into our mind are Yamaha YZF R15 and Honda CBR, both these category bikes are very famous among the young people but because of the high price margins these sport variant bikes are not affordable to many.

Despite of the fact that Suzuki Gixxer SF comes with a full body kit but it is not a track focus bike like the Yamaha R15 rather it is a daily commuting bike which can be occasionally used for touring and highway riding. The Gixxer SF was designed by the same engineers from Japan who designed the Suzuki GSR 1000 which is the predecessor of the Gixxer.

The Gixxer SF was aerodynamically tested in the same wind tunnel where the moto gp bike GSXRR and the Hayabusa was tested; the aim was to deduce the air drag and increase high speed stability. Unlike the aluminum finish on the exhaust pipe and new clam handle bar SF is identical to is sibling Gixxer.

A question might pop up in the readers mind that the sports faring on the Gixxer SF add weight which might make it heavier of a bit slower than the naked Gixxer. The answer is “NO”, despite of the fact that the fairing adds 4kgs weight on the bike but SF reaches a good top speed than the naked Gixxer and reduces more wind blasts. This was an anecdote about the Suzuki Gixxer SF and Gixxer.


Yamaha Fazer Fi V2 Overview

Now let’s talk about the recent launch of the latest bike in the Bangladeshi market the Yamaha Fazer – fi V2. The most awaited bike of the year by the young motorcycle enthusiasts. The new Fazer- fi V2 entered the market through ACI motors previously Yamaha bikes were imported by Karnaphuli motors.

The trend of 150cc touring bike were introduced by Yahama Fazer and then the Japanese rival Suzuki introduced Gixxer SF. The Yamaha Fazer is already a successful model undoubtedly for which Yamaha has decided to upgrade the Fazer. Not only cosmetic changes are done on the Fazer-fi V2 but always Yamaha’s “Blue Core” fuel injection technology was introduced in the Fazer V2. Its new sharper new look has grabbed the eye balls of the motorcycle enthusiasts.

The Fazer was previously known for its refined and smooth engine and now the fuel injection has done its job quiet well and makes the bike’s engine super refined. The previous model fazer had complains about its fuel economy, think of this fact Yamaha has done a good engineering on this Version 2 model by deducting the cubic capacity by a few number which gives a better mileage than the previous one.

Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Head To Head Comparison

The Suzuki Gixxer SF in a single cylindered air cooled 155cc engine with 14.6 Bhp and 14NM torque. It clocks a top speed of 131 km/h and gives a decent mileage about 40km/L. Gixxer SF weighs 139 kg which is definitely the heavier one with its competitor. Whereas the Yamaha Fazer-fi V2 has a 149cc single cylindered two valve engine with 12.9 Bhp and produces 12.8 NM of torque. Yamaha Fazer-fi  V2 is 2kg lighter than the Gixxer SF which mean 137kg and gives a little more mileage about 43km/L. Fazer-fi V2 reaches a top speed about 120km/h.

These were the Engine specs which are mostly given on papers, apart from this the bikes has similarities like they have fully digital meter, an eco-mode indicator, telescopic front suspension, mono shock absorber, alloy rings, front 100/80-17 and rear 140/60-17 tubeless tyres. The Gixxer SF has a gear indicator and two trip meters which misses out in Fazer-fi V2. Fazer-fi V2 is given a well cushioned wide split seat assembly with a new shape grab rail and the Gixxer SF has a single seat and a round shaped grab rail. Gixxer Sf would look sportier if it had a split seat.


Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Styling & Comfort

Both the bikes boast of their looks in their own ways, a fully body kit on the SF makes it look like a Hayabusa from the front and the Yamaha Fazer-fi  with duel headlamp with a semi fairing is a beauty of its genre. The riding position on both the bikes are upright, despite having a sport fair on the Gixxer SF the rider do not have to lean on the handle bars while riding.

The SF has mono color variants like Black, red, Blue (moto gp edition) and White; Fazer has duel color combination with eye catching graphics on it. The Fazer look more edgy, sharper and wider than the SF and SF looks sportier than the Fazer, though there are complaints against built quality of the plastics on Gixxer bike for which Fazer V2 steps one step further towards bonus points as there are no such issues regarding the built quality of the Yamaha bikes.


Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Handling and Power

Yamaha Fazer is well known for its stability, control, better braking, engine refinement but the Gixxer SF excels in terms of power. The suspensions on both the bikes are adequate bump in and out of the pot holes with ease. Gixxer SF can take sharp turns around the corners, can lean more than Fazer while the Fazer makes you feel more comfortable in the twisty.

The gear shifts feels a bit clunky, despite having a 5 speed gear box in the Gixxer  SF, but the SF has a crispy throttle, the engine is tuned to broad low end torque and punchy mid-range, just twist the throttle, you can feel the raw power of the engine and the fairing help you to main a three digit speed very smoothly.

Speed or engine performance is not what you always need, riding comfort, better fuel economy, and a much refined engine brings satisfaction to a rider, in which the Fazer V2 takes all the points, tapping brakes at a higher speed on a Fazer you would feel the level of stability this bike provides, a smoother engine sound brings rhythm while riding, the semi faring is ample to give the rider wind protection.

Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Drag & Brake

If both the bikes are put on to a drag race surely the Suzuki Gixxer SF will win with a substantial margin but while braking from a high speed to zero, Fazer has the best braking record.


Suzuki Gixxer SF vs Yamaha Fazer Fi V2 – Verdict

Choosing one bike over the other would not be wise enough at a glance because both the bikes are priced at a margin of 3 lac BDT, so which on to choose is purely subjective. We have tried to cover all the major points here in this article, keeping in mind which bike serves your purpose of riding you can easily choose any one of these motorcycles. If you want a performance bike with high speed, much power and Sporty looking motorcycle then go for Suzuki Gixxer SF and if you want a bike with best comfort, smooth engine and better braking then Yamaha Fazer-fi V2 is what you need!

Carburetor Vs Fuel Injection – Which Is Best?

Perhaps not all the bikers know about the functionality of a carburetor on their motorcycle or has a very little interest in it. This little thing can bring a massive change in your riding experience. Today, let’s glimpse into the world of fuel delivery. Why do more and more motorcycles now a day have fuel-injection systems rather than carburetor?  So here is our discussion Carburetor Vs Fuel Injection – Brief Discussion.


The carburetor is one of the most essential mechanical part on a motorcycle and many small engine machines. All engines require a proper mixture of air and fuel for combustion; this vital device known as the carburetor controls the ratio of the fuel/air mixture entering the engine.

This sounds simple enough, but all the components inside it has to work properly for the efficient output. There are many carburetor parts that, if not set properly, will at best cause the bike to run properly, or at worst keep it from not running at all. The correct ratio of fuel and air is crucial for engine performance.


Carburetor – How Does It Work

Air enters the carburetor from the air intake or through the air filter, and speeds up gradually, due to the narrowing of the interior walls of the carburetor. This air is blowing perpendicular to the throttle slide – a valve controlled from the throttle cable. When the throttle is pulled it is opened, the cable raises the throttle slide located inside the carburetor’s main body. As the slide rises, the fast moving air pulls the fuel up the main jet from the float chamber.

This works automatically because the fuel wants to travel from an area of high pressure (the float chamber) to an area of low pressure (the carburetor main body). The fuel mixes with air and heads into the engine. The amount of fuel that flows is dependent on the position and size of the needle valve, the size of the main jet, and the height level of the fuel in the float chamber.

The fuel height in the float chamber is controlled by the floats. Adjusting these floats correctly inside the carburetor is very important. As a vehicle ages it may develop vacuum air leaks from the many vacuum lines used in the engine compartment. These leaks cause additional air to be drawn into the intake manifold, changing the fuel/air mixture from the right blend of fuel and air to more of a lean mixture – too much air, not enough fuel.  Any time you add additional air to the intake system with the same amount of fuel as before, it results in a very high combustion chamber temperature.

A carburetor is dependent upon the velocity of air entering the venture to create a good air/fuel mix to feed the engine, and serves to maintain the fuel circuits which pump the petrol – and although the majority of current high-performance bikes have switched to fuel injection, there are still plenty of motorcycles fitted with carburetor engines.

Float Chamber Components:

Needle valve assembly
Float pivot rod
Chamber and gasket
Drain plug.

The float chamber is a reservoir for fuel, and contains all of the working components of the float. Most float chambers have a drain fitted for maintenance and, in some cases, to measure the actual fuel height.

A carburetor also lets some fuel evaporate because it is an open system. The air intake is not sealed when the bike is not running. Fuel pooled in the carb evaporates. The lost fuel is a very small even over the lifetime of a motorcycle. Cold weather can be a problem when starting the engine. Even push starts can’t overcome this.


Electronic Fuel Injection: EFI

Nowadays, most rider turns the key in the ignition, jump on and speed off without a second thought and that’s because a fuel injected engine makes cold starts much easier. Technically, though, the mechanics are far more complex. First of all, there’s a fuel pump inside the tank, an electronic engine controller and an assortment of sensors.

The fuel injected system is controlled by a computerized fuel delivery system, while the ECU takes information from various sensors and determines how much fuel the engine receives based on this data. Other sensors deal with RPM, engine temperature, throttle position, and the crankshaft position.

Additionally, the fuel required for each RPM and engine load condition is located in the fuel map within the ECU. Once the amount of fuel is identified, the ECU will adjust the fuel mixture for the engine and air intake temperatures. Computer-controlled, electronic fuel injection systems consist of a computer, an oxygen sensor, a set of fuel injectors, a fuel pressure regulator and an electric fuel pump. When the key is turned on the ECU runs through a quick self-check that tells it everything is ready to go.

Fuel injection engines for motorcycles function similar to those in cars, trucks and other modern engines. Fuel injection engines are controlled electronically by the Engine Control Unit (ECU), a small computer within the engine that measures many variables (such as throttle, RPM’s, air and engine temperature, and crankshaft position) in order to determine how much fuel should enter the engine through the fuel injectors, thus creating less emissions and wasted energy and creates a more responsive acceleration for the rider.

All modern motorcycle fuel injectors are capable of opening and closing many times per second. In a sense, Electronic Fuel Injection is a lot simpler than a carburetor. Reduced to its essentials an EFI system is nothing more than a nozzle that sprays fuel into the airstream whenever a computer tells it to.


In particular the processes the computer uses to determine how much fuel to supply can get pretty complicated. Fuel injection uses a high pressure pump to deliver fuel under pressure to another point in the intake sequence, much closer to the piston head. In fuel injection, the air to be burned comes without coming into contact with the fuel, and the fuel is sprayed (“injected”) into the air stream as an atomized mist.

Modern engines last longer because they have electronic fuel injection that simply corrects the air/fuel ratio so you never have an excessively rich or lean condition. This is the main reason spark plugs last longer, valves are not burned and piston rings do not lose their tension resulting in shorter engine life.

If the problem is too great for the computer to correct, it will turn on the check engine light located on the meter which is your clue to take the vehicle to a mechanic to correct the problem. Fuel injector gives a slightly higher engine performance and slightly more efficiency when running at the best fuel-air ratio. Throttle response is also a bit better. Example: Yamaha FZ-fi, which is a recent launch in Bangladesh.


Crucially, most carburetor problems can be fixed easily at the side of the road with an assortment of basic tools. An electronic fuel injection system, though, if it goes wrong, will usually require a new part – and that’s going to cost you. Repair is far more difficult. Today’s modern fuel injection systems require a computer to diagnose the problem.

There is little doubt in the fact that Fuel Injection will soon replace carburetors because of the emission norms that keep getting stricter every year. However, there is little doubt that unless the cost of this new-age technology comes down significantly the majority will keep on sticking to carburetors. If you talk about numbers, a nicely tuned carburetor has its peak power just 10% lesser than that of a Fuel Injected mill which is not much keeping in the mind the extra money it comes for.

What makes it highly efficient is its ability to constantly tune the air-fuel mixture benefitting the engine and enhancing its life. Still, we are, like many others, struggling to find which one is better here as both of the options have their own pros and cons, and everything for or against them is a big reason to either go or not go for any particular player here. So, depending on your need and how much you like to play around with the performance of your motorcycle, choose the one that suits you the best.
