7 Common Mechanical Issues of Motorcycle Crashes

Riding motorcycles is an exhilarating and liberating experience. But the risks along with it should not be ignored. Many motorcycle accidents are caused by external factors such as road conditions, rider error, and so on. But mechanical issues also play an important role in these crashes.

According to the relevant data on motorcycle accidents, many serious injuries or fatalities are caused by poorly maintained.

To ensure a safe riding experience, every motorcyclist should understand the common mechanical problems of motorcycles. So that we can take action to prevent crashes.

In this article, the most common mechanical issues of motorcycle crashes will be explored. You will know how these mechanical issues affect safety, and some tips to avoid them. Staying informed about these problems is crucial to every motorcyclist, no matter how long you have been riding.

1. Brake System Failures

For any motorcycle, the braking system is one of the most essential components.

If the motorcycle's ability to stop safely is compromised because of brake failure. Some terrible accidents may occur. Problems can easily occur if the brake system lacks maintenance.

The most common cause of brake failure is owner neglect. 

Brake failure caused by the owner's negligence includes:

Worn Brake Pads: The most common cause of brake pads is prolonged use. At the same time, the brake pads are less effective. We should replace them regularly to make sure they provide adequate stopping power.

Leaking Brake Fluid: This process of transferring force from the lever to the brake mechanism cannot be separated from brake fluid. If brake fluid leaks, the pressure will drop, causing brake problems.

Warped Rotors: Bent or damaged rotors can increase stopping distance and reduce control of the motorcycle, causing uneven braking.

Air in Brake Lines: The hydraulic pressure may be reduced because of the air bubbles in brake lines. As a result, the brakes will be spongy or worse, ineffective.

How to Avoid Brake Failures

Replace the brake pads regularly when they are thin.

Check your brake fluid level (top it up if necessary). To prevent contamination, you'd better replace it once a year(or every two years).

It is important to know whether the brake lines are leaks or cracks. Then, decide whether to replace it according to the actual situation.

Please check your motorcycle's rotors to see if they are warped. Then resurface or replace them if needed.

2. Tire Problems

As tires are the direct contact point between the motorcycle and the road, any tire problem can directly impact your ability to maneuver, stop, or accelerate.

Common tire-related problems include:

Underinflated Tires: Low tire pressure not only reduces grip but also increases the risk of tire blowout. At the same time, it will be more difficult to handle the motorcycle.

Overinflated Tires: Sometimes, the tire's contact patch with the road is reduced because of excessive pressure. The motorcycle's traction and stability will also be reduced.

Cracks or Dry Rot: Some sudden failures may caused by old or poorly maintained tires with cracks.

Worn Tread: On wet or slippery roads, worn-out tires fail to provide enough grip.

How to Avoid Tire-Related Crashes

To keep the tire pressure and check it regularly, follow the manufacturer recommendations in your motorcycle’s user manual, please.

Normally, the tread depth should not be lower than 2/32 of an inch (or as recommended by your region). Please check it and replace it if needed.

Don't forget to look for visible signs of damage, like cracks or bulges.

As rubber degrades over time, please replace the tires every 5-6 years, even though they look in good condition.

3. Chain and Sprocket Issues

The transmission of power cannot be separated from chain and sprocket. As long as they have problems, there will be power loss or even a complete mechanical failure.

The most common issues include:

Loose Chain: Sometimes, the motorcycle will suddenly lose power as the rear wheel locking. That is because the chain is too loose to keep on the sprockets.

Overtightened Chain: The chain can not be too tight either because an overly tight chain will put more strain on the drivetrain. And the chains will be more susceptible to wear and failure.

Worn Sprockets: The chain on sprockets can be easier to skip because of the worn or damaged sprockets. And then lead to jerky or unpredictable power delivery.

How to Avoid Chain and Sprocket Failures

Chain tension is essential as too loose or too tight can cause motorcycle failure. As a result, inspecting and adjusting the chain tension regularly becomes a necessity.

As rusty and worn chains are more likely to cause motorcycle failure. Please clean and lubricate your motorcycle chain regularly.

The condition of the sprockets is also important. Whether they are worn out (hooked or uneven teeth) determines whether we should replace them.

When the chain and sprockets are all in bad condition, such as severe wear and tear, replace them.

4. Engine Malfunctions-top 1 in mechanical issues

When the motorcycle is traveling at high speed, a traffic accident may occur, as long as there is a problem with the engine. So no one can deny that the motorcycle's heart is the engine.

Common engine issues include:

Overheating: Sometimes, the motorcycle suddenly loses power, probably because the engine got too hot and seized up.

Oil Leaks: When riding on the road, Oil leaks can cause the motorcycle to slip. And engine damage may caused by insufficient oil as well.

Spark Plug Problems: If the spark plugs become dirty or worn, misfires may happen while the power is reduced and the motorcycle becomes hard to control.

Clogged Air Filters: If the air filter is not clean, the engine performance will be reduced while the risk of stalling increases.

How to Avoid Engine-Related Crashes

To avoid oil leaks, regularly checking the oil level is necessary. At the same time, we should top it up if needed.

Because the cooling system is irreplaceable, inspect it to make sure the radiator and coolant levels are adequate, please.

The articles "How Often Should You Replace Motorcycle Coolant?" and "How to Change Motorcycle Coolant" will provide you an ultimate guidance about coolant replacing.

Remember it is also an important part of routine maintenance to clean the air filter or replace it.

Please replace the spark plugs in time if they appear dirty or worn.

5. Faulty Suspension

All of us should pay attention to the importance of the suspension system as motorcycles need to keep smooth and control.

Common suspension issues include:

Worn Shock Absorbers: A motorcycle's reduced ability to absorb bumps could be due to wear and tear or leaks of shock absorbers. When a motorcyclist is riding a motorcycle, he or she may feel the bumps because of this.

Misaligned Suspension: The steering and control functions of the motorcycle can be affected by improperly aligned suspension components. The most obvious feature is that the motorcycle will pull to one side.

Weak Springs: As the spring loses tension, it also reduces the suspension's ability to handle weight and road conditions.

How to Avoid Suspension Problems

Some signs of wear (leaks or sagging) on the suspension system should be checked regularly.

Check if the suspension components are misaligned, if so, ask a professional to adjust it.

If the shock absorbers and springs are worn or damaged, replace them, please.

Understanding how much can you carry on your motorcycle, and avoid overweight in your daily use.

6. Electrical Failures

Electrical systems are used by most modern motorcycles. They are used to operate critical components including the ignition, lights, and indicators. So if there are any electrical failures, some dangers will occur. In low visibility conditions like night, the potential for danger increases significantly.

Common electrical problems include:

Dead Battery: You can't start the motorcycle because of a weak or dead battery.

Faulty Wiring: Some intermittent failures such as light and indicator malfunctions are caused by damaged or corroded wiring.

Blown Fuses: A blown fuse can disable some essential components, such as the headlight or horn.

How to Avoid Electrical Failures

You'd better replace your battery if it has been used for more than three years (or five years) or signs of weakness occur. Please test the battery regularly to check if it needs to be replaced.

Inspect the wiring and according to the damage to the wiring, such as frayed or corroded wires, decide whether to repair or replace the wiring.

Learning how to change fuses is important. Because you can change them in an emergency by yourself if there are spare fuses in your motorcycle.

7. Fuel System Problems

The fuel system delivers the correct amount of fuel to the engine. Any disruption in this process can lead to performance issues or even a complete engine shutdown.

Common fuel system problems include:

Clogged Fuel Lines: If there is debris or dirt in the fuel lines, the flow of fuel will be impeded. At the same time, the engine of the motorcycle will sputter or stall.

Dirty Carburetor or Fuel Injectors: The fuel delivery and engine performance can be affected by clogs with dirt or residue in the carburetor or fuel injectors.

Fuel Leaks: Leaks in the fuel system are wasteful and dangerous with increased fire risk.

How to Avoid Fuel System Issues

Use clean and high-quality fuel to replace the old fuel in the tank of the motorcycle which has remained for a long time.

Regard it as part of routine maintenance to clean the carburetor and fuel injectors, and never forget to finish.

Never let the fuel lines and connections get damaged or leaked, if so, repair them as soon as possible.

Conclusion

Proper maintenance and regular inspections are necessary if you don't want to encounter a motorcycle accident caused by mechanical failures. We can also decrease the accident risk by staying vigilant and addressing issues before they get worse.

Not only does riding safely mean wearing the right gear or following traffic rules but also need to ensure your motorcycle is in top condition.

Remember, your motorcycle is a machine, and it requires care and attention, as any machine does. Make maintenance a priority, and then you'll have a safer ride and a longer motorcycle life.
