Measuring Motorcycle Chain with a Tool

Adjusting motorcycle chain tension should be part of your regular motorcycle maintenance. While the adjusting process can be done by referring manufacturer’s guidelines and some tools there is a possibility of leaving the chain loose or overly tight.

This is where motorcycle chain tension tools come into play. These tools are handy equipments to measure and adjust the motorcycle chain tension effectively.

In this comprehensive guide and review post, you will know the importance of motorcycle chain tension tools, how to use them, and why they are an essential addition to your motorcycle maintenance arsenal.

Furthermore, we will guide you through the process of choosing the right motorcycle chain tension tool with our buyer’s guide and also help you find 3 best motorcycle chain tension tools to choose from.

Why Chain Tension Matters

Motorcycle chains are prone to wear and tear and damage due to the constant accumulation of dirt and debris during regular usage.

The circumstances can lead to worn-out sprockets, bearings, etc. resulting in loosely gripped motorcycle chains. An excessively loose chain can skip teeth, leading to a sudden loss of power. At the same time, an overly tight chain can strain components and potentially snap.

If the chain is not properly adjusted, it can lead to inefficient power transmission, poor acceleration, and less responsive ride which can be life-threatening in the long run.

Correct chain tension improves your motorcycle’s overall performance minimizing wear and tear on the chain, sprockets, and other drive train components.

If you want to extend the lifespan of your motorcycle chain and save money on costly repairs or replacements then correct chain tension is necessary.

What Is a Motorcycle Chain Tension Tool?

A motorcycle chain tension tool, also known as a chain slack tool, is a device designed to measure and adjust the tension in your motorcycle’s chain accurately.

These tools come in various types, including manual and digital variants. As mentioned earlier, you can use some manual items such as measuring tape, spanners, wrenches, etc. to perform the adjustment task.

However, there is always a risk of inaccuracy while adjusting the chain tension manually. Moreover, it also takes time and effort which many motorcyclists fail to invest.

Having a dedicated tension tool helps you maintain consistent chain tension every time you adjust it.

These tools provide precise readings, ensuring that you set your chain to the manufacturer’s recommended specifications.

In terms of usage, most chain tension tools are user-friendly and do not require advanced mechanical knowledge. They typically include clear instructions for use.

While adjusting, over-tightening a chain is a common mistake performed by many motorcyclists that can lead to costly repairs. Chain tension tools help prevent this by providing a reliable reference point ensuring optimal performance and safety.
