Chain and sprockets are one of the main components of a motorbike. They perform the function of transmitting power from the gearbox to the rear wheel. A motorbike consists of two sprockets and a chain.
A sprocket is a wheel with teeth to which perforated chains are attached. The sprocket in the font is smaller, called the ‘driver’, and connected to the transmission output shaft. The sprocket in the back is larger and is called the ‘driven’.
These sprockets and chains being faulty will lead to tension loss, risk of slippage, crippled chain, and costly downtime. So it is crucial to take good care of these components and replace them when faulty.
This post will walk you through the signs and tips for maintaining and replacing the sprockets and chains.
Signs your chain and sprockets need replacement
These are the signs you have to look for to know whether your chain or sprockets need a replacement.
- Chain stretch: The chain will get stretched over time due to the constant force and wear from the bike’s output power.
- Worn sprocket tooth: A healthy sprocket tooth is uniform in shape with a rounded profile. Inspect the sprocket regularly and if the teeth are worn out and hooked then it’s time to replace the sprocket. A worn-out sprocket can cause chain slip that leads to damage to other components and injury to the rider.
- Stiff Links and Rust: Stiff links effects the smooth transition of the power. Stiff chain is caused due to:
- Lack of proper lubrication
- Accumulation of dirt and debris
- Rust and corrosion
- Chain wear and damage
- Incorrect chain tension
- Improper installation or Adjustment
- Excessive Noise: Sometimes the worn-out sprockets and chain will produce unusual noises like rattling or grinding. If you notice these kinds of noise coming from the drivetrain then it is an indicator to replace the component.
- Misaligned or worn chain links: A chain that is visibly misaligned or has uneven wear across the links should be replaced immediately. This can be caused by poor tensioning, a bent sprocket, or the chain simply reaching the end of its lifespan.
Maintenance of the chain and sprockets
Now let’s look at some tips to take care of the chains and sprockets.
- Regular Cleaning: When you ride off-road or in rain the dirt and grim gets accumulated so fast. In such cases, a good cleaner or a degreaser should be used to remove the buildup that can cause wear.
- Lubrication: Lubrication helps in reducing the friction between the chain and the sprockets. So it is an important step to lubricate the chain properly. Use a high-quality motorcycle chain lubricant and apply it after every ride or at least every 500 kilometers. The excessive lube should be wiped off as it can cause the dirt to get accumulate.
- Proper Chain Tension: Always refer to the manufacturer’s manual to maintain the correct chain tension. The tension of the chain should be checked regularly for smooth power transmission. A chain that is too loose or too tight will cause premature wear.
- Inspect Regularly: This is the most important step always do regular inspection of the chain and sprocket. Pay close attention to signs of wear, rust, or damage. Identifying issues early can prevent more serious problems down the road. Inspection should not be limited to the chain and sprockets of your motorbike every part should be inspected regularly to maintain the bike in good condition.
Conclusion
Maintaining your motorbike’s chain and sprocket is crucial for performance, safety, and longevity. Regular inspections, proper cleaning, lubrication, and timely replacement of worn parts can help avoid costly repairs and unsafe riding conditions. Remember, chains and sprockets wear together, so it’s always wise to replace them as a set when the time comes. It is also good to get professional inspections to gain in-depth insights into your motorbike’s condition.
