The motorcycle chain is one of the most important components of the transmission system. It ensures the transmission of power from the engine to the wheels, allowing your motorcycle to move. However, like all mechanical parts, it wears out over time and requires regular maintenance, or even replacement, to ensure optimal performance and your safety on the road. In this comprehensive guide, Karraz Motors explains everything you need to know about replacing your motorcycle chain: why it is important, when to change it, and how to do it.
1. Why is it crucial to replace the motorcycle chain?
Your motorcycle's chain is responsible for transferring power from the engine to the rear wheel, allowing your bike to move forward. It must therefore be in perfect condition to ensure a smooth and safe ride. Here's why it's crucial to properly maintain and replace your motorcycle's chain:
1.1. Performance and power transmission
If the chain is worn, loose or damaged, it can have a direct impact on the performance of the motorcycle. An incorrectly tensioned chain can reduce the efficiency of power transmission, resulting in a loss of speed or poor response when accelerating.
1.2. Security
A chain in poor condition can break or come loose while driving, creating a serious risk of accident. It is therefore essential to ensure that it is always in good working order to avoid any incident on the road.
1.3. Premature wear of other components
A worn chain can cause premature wear on the sprocket and chainring. This can lead to additional costs to replace these other components, as a worn chain can damage them more quickly.
2. When should the motorcycle chain be replaced?
The lifespan of a motorcycle chain depends on several factors, such as the type of motorcycle, the type of riding, and road conditions. Here are some signs that it's time to replace your chain:
2.1. Excessive extension of the chain
Motorcycle chains naturally stretch over time due to wear on the links and teeth. When the chain becomes too long (i.e., it has exceeded its recommended extension limit), it can no longer be properly tensioned, which can cause skipping or derailment. Most chains should be replaced when the extension reaches 1 to 2% of the original length.
2.2. Unusual noises or vibrations
A worn or poorly tensioned chain can produce unusual noises, such as clicking or squeaking. If you notice vibrations in the handlebars or the motorcycle, this can also be a sign of a damaged or faulty chain.
2.3. Rigid links
Chain links must be flexible to ensure smooth power transmission. If some links become stiff or jammed, it can result in poor performance and safety hazards. Inspect the chain regularly to ensure all links are functioning properly.
2.4. The appearance of corrosion or rust
Corrosion is one of your chain's worst enemies. If you see rust or signs of oxidation on the chain, it indicates that it has been exposed to moisture or extreme weather conditions. A rusty chain loses efficiency and can break quickly.
2.5. The teeth of the sprocket or chainring are worn
If the teeth on the sprocket or chainring are very sharp or have visible wear marks, this means that the chain has suffered too much and must be replaced to avoid damaging these other components.
3. How to replace the motorcycle chain?
Replacing your motorcycle chain may seem like a daunting task if you've never done it before, but with the right tools and a little patience, it's a fairly simple task. Here are the steps to follow to properly replace your motorcycle chain:
3.1. Prepare the necessary tools
Before you begin, you will need the following tools:
- A new chain suitable for your motorcycle.
- A chain tool or chain shortening tool.
- A screwdriver or wrench to remove the chain guard.
- An adjustable wrench or socket to remove the pinion nut.
- A jack or stand to lift the motorcycle and stabilize it.
3.2. Lift the motorcycle and remove the rear wheel
To access the chain, you will likely need to remove the rear wheel from the motorcycle. Raise the motorcycle using a jack or a stable stand, then unscrew the rear wheel nut to remove it.
3.3. Loosen the chain
Before removing the chain, you will need to loosen it by loosening the rear wheel axle. This allows the chain to slacken and be easier to remove.
3.4. Remove the worn chain
Use a chain tool to remove the links from the chain. Some chains have quick-release links that make disassembly easier, but if they don't, you'll need to cut the chain with a chain tool.
3.5. Install the new chain
Place the new chain around the sprocket and chainring, then adjust it to the correct length. To do this, use the breaker tool to add or remove links as needed. The new chain should be perfectly aligned and tight. Don't let it be too loose, but don't overtighten it either.
3.6. Reinstall the rear wheel and adjust the tension
Once the new chain is installed, reinstall the rear wheel, making sure the axle is tight. Then, adjust the chain tension so that it has about 2 to 3 cm of play when you press it in the middle.
3.7. Check alignment and adjustments
Make sure the rear wheel is properly aligned and the chain is tight before setting off. Do a few low-speed tests to check that the chain is working properly.
4. Maintenance tips to extend the life of your chain
Once the chain has been replaced, it is important to maintain it regularly to extend its life and avoid frequent replacements. Here are some tips:
- Lubricate the chain regularly : Applying specific motorcycle chain lubricant helps reduce wear and keep the links flexible.
- Check chain tension : A chain that is too tight or too loose can cause premature wear. Check the tension regularly and adjust if necessary.
- Clean the chain : Dirt and mud can build up on the chain, accelerating its wear. Clean it with a suitable chain cleaner and a brush to remove impurities.
- Check the sprockets and chainring : Regularly inspect the sprocket and chainring to ensure they are not excessively worn.
