What Happens If a Motorcycle Chain Breaks: The Risks

One critical component that often goes unnoticed until it fails is the motorcycle chain. What happens if a motorcycle chain breaks, and how can you prevent this from occurring on your next ride?

In this article, we’ll delve into the causes, risks, and solutions related to a broken motorcycle chain to help you understand its implications and keep your ride on track.

Here Is What Happens When Motorcycle Chain Breaks

A broken motorcycle chain can have several serious consequences:

  1. Loss of Power: With a broken chain, power from the engine cannot be transferred to the rear wheel, rendering the motorcycle immobile. This can leave you stranded on the road.
  2. Risk of Accident: A sudden chain break while riding can lead to a loss of control and a potential accident. This is especially dangerous at higher speeds.
  3. Damage to the Bike: A broken chain can cause damage to other parts of the motorcycle, such as the engine casing, sprockets, and rear wheel, which can result in costly repairs.
  4. Towing and Repairs: If your chain breaks, you may need to arrange for a tow to a repair shop, incurring additional costs and inconvenience.

The Role of the Motorcycle Chain

Before we explore the consequences of a broken motorcycle chain, let’s first understand its significance in your motorcycle’s operation. The chain is a vital component of the motorcycle’s drivetrain, responsible for transferring power from the engine to the rear wheel. It’s an essential link in the mechanical system that propels your bike forward.

Causes of a Motorcycle Chain Break

A motorcycle chain can break due to various reasons, including:

  1. Wear and Tear: Over time, chains naturally wear out. Regular maintenance, such as lubrication and tension adjustments, can extend their lifespan, but eventually, all chains will degrade.
  2. Lack of Maintenance: Neglecting proper chain maintenance, such as failing to lubricate it regularly or not keeping it at the correct tension, can accelerate wear and increase the likelihood of a break.
  3. Rust and Corrosion: Exposure to moisture and environmental elements can lead to rust and corrosion, weakening the chain’s integrity.
  4. Chain Age: Chains have a finite lifespan, and older chains are more prone to failure, even with proper maintenance.
  5. Overloading: Carrying excessive weight or luggage on the motorcycle can strain the chain, increasing the risk of breakage.

Preventing Chain Breaks

Preventing a motorcycle chain break is essential for rider safety and the longevity of your bike. Here are some preventive measures:

  1. Regular Maintenance: Perform regular chain maintenance, including cleaning, lubrication, and tension adjustments, as per your motorcycle’s manual.
  2. Inspect for Wear: Regularly inspect the chain for signs of wear, such as stretched links or damaged rollers. Replace the chain when it reaches the end of its service life.
  3. Keep Proper Tension: Maintain the correct chain tension to prevent excessive stress on the chain and sprockets.
  4. Protect from Rust: Keep the chain clean and well-lubricated to protect it from rust and corrosion. Use a chain-specific lubricant.
  5. Weight Considerations: Avoid overloading the motorcycle with excessive weight or cargo.
  6. Replace Sprockets: When replacing the chain, consider changing the sprockets as well to ensure even wear.


In conclusion, a broken motorcycle chain can have significant consequences, from rendering your ride immobile to posing a safety risk. Preventive maintenance and regular inspections are key to minimizing the chances of a chain break.

Remember that safety always comes first, and addressing chain issues promptly can ensure a smoother and safer ride on the open road.
