4 Most-Common Problems With the Yamaha Aerox

If you are looking to buy your next scooter, the Yamaha Aerox is a superb choice. It offers breathtaking speed and handling and is loaded with premium features.

However, you need to know the common problems associated with these models.

Here are the most common issues with the Yamaha Aerox:

1. Bike Running Problems

Everyone buys his/her bike and expects it to run flawlessly.

Sadly, this is not the case for some Yamaha Aerox owners.

These riders report experiencing multiple running problems with their bikes, which often makes for erratic performance and plenty of headaches.

Below are some of the Aerox motorcycle’s running issues:

Bike Refuses to Start

A common complaint among Aerox owners is that their bikes refuse to run at all on certain occasions. Typically, your bike should start once you activate the electric starter.

However, activating the starter on the affected Aerox bikes hardly gets them to run. Instead of the engine roaring to life, the electric starter merely turns over, and the bike shows no signs of starting.

When these bikes come to life, it is after the hapless owners have made multiple efforts to start them. In some cases, the bikes won’t run until after 10-20 start attempts. This problem is common during chilly weather or when the bike has been in disuse for long.

Bike Loses Power and Stalls

Another running issue with the Aerox bikes is that they often “cut out”, i.e. they lose power and stall.

Most times, the pattern is the same: the owner starts the bike, rides it for a few minutes, and then the bike stalls.

For some, the stalling occurs when the bike reaches a certain temperature. In such cases, the scooter may lose power after the bike has been running for some time e.g. at a red light.

Not only does this affect performance, but it also puts the rider at risk of a collision or crash.

And even if the rider doesn’t suffer a mishap resulting from the bike stalling, no one enjoys having his/her bike dying during a trip.

Possible causes for these running problems include:

  1. Battery Issues: A bad battery could be responsible for the inability of the Aerox bike to start. Some batteries tend to drain if left unused for a long time. This would explain why some find it difficult to start the bike after a period of disuse.
    • If your Aerox bike takes time to start when cold, don’t fret. The problem is common to many bikes, not just the Aerox models, and is quite pronounced on frosty mornings.
    • A simple fix for this problem is to use the Kickstarter, instead of the electric self-starter. Try pulling out the choke before doing this, to make it more effective.
  2. Air leaks: Air leaks will cause an imbalance in the air-fuel ratio and force the engine to run lean. If this happens, it could cause the bike to stall after a period of use. Examine the bike to find the leak area, seal it up, and see if the problem stops.
  3. Faulty spark plugs: If your spark plug isn’t giving the spark necessary for ignition, your bike won’t start. The regular solution is to clean the spark plug in case it is fouled or buy a new one.
  4. Faulty air/fuel filters: Clogged-up air and fuel filters will cause the engine to either run lean or rich. Both can lead to engine stalling and losing power.

2. Ride Quality Is Poor in Some Situations

Although it’s a small scooter, the Aerox has great cornering and handling ability, thanks to a sporty design.

However, the stiff suspension means ride quality can be compromised, especially when riding over bumps and other uneven surfaces.

Moreover, some complain that the seat is unsuitable for long drives and leaves them sore.

However, this complaint isn’t particularly widespread, and the Aerox remains a good daily driver.

3. Bike Vibrates Excessively

It is normal for a motorcycle to vibrate. However, excess vibration can make the ride rough and reduce the joy of riding.

Some complaints concerning the Aerox bikes have revolved around their tendency to vibrate excessively.

The bikes are said to vibrate heavily, with the riders feeling these vibratory effects in their hands/legs. This often affects ride quality and dampens the riding experience.

Possible causes:

  1. Improper wheel bearings: Bad wheel bearings can cause your bike to vibrate, especially at specific speeds. One way to know if a bad wheel bearing is at fault is to examine your wheels. To do this, lift each wheel and rotate them. Check for any squeaking noises or extra effort needed to turn the wheel. These signs mean your wheel bearings need replacement.
  2. Unbalanced crankshaft: Bad crankshaft bearings can cause your bike to vibrate, especially at higher RPMs.
  3. Variator issues: Some Aerox owners report that their bikes vibrate while idling or at low speeds. If this is the case for you, your bike’s variator may be at fault. A variator is a component in scooters that controls the engine’s speed.

How does a variator affect vibration? If it’s faulty or improperly set up, your engine may operate at low RPMs in low-speed situations. This will cause the engine to lug slightly, leading to the vibration at low speeds.

Tuning the variator to allow for more engine RPM at low speed should solve the problem. There are several resources online that can teach you how to tune your scooter’s variator properly.

4. Repeated Electrical Problems

Electrical problems can be frustrating for owners, as they often prevent bikes from functioning flawlessly.

Aerox owners have had their fair share of electrical problems.

Some of these include:

  1. Electric Starter Malfunctions: Your bike’s electrical starter should function only if you activate it. However, the starter may try to turn over without you actually activating it. In such a situation, the starter is clearly malfunctioning.
    • Most diagnoses reveal this problem results from the starter relay ‘shorting out’.
    • The shorting out will force the switch into a constant “ON” setting, which would explain why the starter is turning over when it should not.
  2. Indicators/Dash Lights Don’t Work: If you start up your bike and the indicators don’t come up, then something’s wrong with your electricals. It could result from faulty regulators, rectifiers, grounding connectors, or even bad batteries.

Pros of Yamaha Aerox

Here are some advantages of the Yamaha Aerox:

1. Impressive Performance

The Aerox comes with a 155cc, liquid-cooled, single-cylinder engine that offers around 15 bhp (brake horsepower) of torque and 13.8 Nm of torque.

This makes the Aerox arguably the best performing model in its segment.

Besides, this model comes with Variable Valve Timing (VVT), which gives the following benefits:

  1. Higher RPM
  2. Lower fuel consumption
  3. Reduced carbon emissions
  4. Longer engine lifespan

2. Attractive Design

There’s no denying that the Aerox is one of the best-looking shooters on the market.

The model’s aggressive and sporty styling is further enhanced by an angular silhouette and sharp lines.

3. Adequate Braking Capabilities

Brakes are an important part of any bike and help you stop your bike safely.

The Aerox offers decent braking power, thanks to a front disc brake and drum rear.

Models also come with an Anti-Lock Braking System (ABS) that provides excellent braking power on wet surfaces.

4. Advanced Features

One of the best things about Aerox is the many features it offers.

For example, Aerox models come with a smart key feature that lets the rider remotely lock or unlock the scooter. This feature helps protect your scooter in crowded parking spaces.

All you have to do is press the key and your scooter will emit a beeping sound and flash its lights.

Another impressive feature on the Aerox is the dial assembly at the front panel. This component makes it convenient to turn the scooter on and off and open the fuel door and storage compartment.

You can even lock the steering wheel to prevent criminals from stealing your bike.

Other features include a digital instrument panel, LED headlight and taillight, and mobile charging socket.

5. Good Storage Options

The Aerox comes with a sizeable cargo-holding capacity, thanks to an under-seat storage compartment.

With this, you can keep things like helmets, food, books on your bike.

There’s also a glove compartment where you can store small items such as keys, phones, wallets, etcetera.

6. Great Gas Mileage

Despite the amount of power it offers, the Aerox doesn’t guzzle fuel.

This is mostly because of Yamaha’s Blue Core technology that helps keep fuel consumption low.

Cons of Yamaha Aerox

The following are some shortcomings of the Yamaha Aerox:

  1. Bike Running Problems
  2. Ride Quality Is Poor in Some Situations
  3. Bike Vibrates Excessively

What Do the Reviews Say?

“The Aerox S handles very much like a scooter, albeit sharper and more agile. The suspension isn’t anything fancy… but it was enough to have a blast, especially with the wide, sporty tires. The suspension also does a good job of absorbing road bumps.”

“Like most scoots the Aerox GP1is also practical. Underseat storage is big enough to hide a helmet, and the leg guards provide enough wind protection to stop flares fluttering in the breeze. In short, the Aerox GP1 represents a massive dose of race-style cool in an already fun and cool sector.”
