Best Dirt Bike Chains and Sprockets Guide & FAQ

Tensile Strength

It is one of the top features to look at when buying a chain and sprocket kit for your dirt bike. Tensile strength is the amount of weight your bike can withstand. You can enjoy better chain and bike efficiency if you go for pre-stretched chains. Typically, a strong chain should carry as much as 8000 pounds load.

Chain or Sprocket Size

Also, find out the size of your motorcycle chain. Measure the intervals in the rollers that are in the chin. It is often measured in pitches. In a sprocket, the distance between points is the size of your sprockets. You will need to buy a chain of equal size as your sprocket to ensure quality power transfer, efficiency, and top speed.

Design Material

Also, you will need to know the material with which your chain or sprocket is constructed. As you can see on our list here, kits are either made of Chromoly steel alloy, steel, aluminum, carbon steel alloys, or gold plate. Typically, chains made of carbon steel alloys are strong enough to withstand wear and are less susceptible to corrosion.

Frequency and manner of Usage

You also need to consider the manner and frequency of usage to know which chain model suits your dirt bike. You can opt for 520 chains if you want an increase in the power of your dirt bike. For speedsters, 530 dirt bikes and motorcycle chains are the best. It can handle high-displacement engines of up to 1000cc.

Frequently Asked Questions 

Q: How do you know that the motorcycle chain is ready to change?

If we want to identify the chain’s wear, we have two indicators: 

  1. First, when there is no more room for tension.
  2. Second, if some links do not move freely, overlapping and breaking the line they form between them. 

In the first case, it is clear; you have to clean and lubricate the chain, as we have already explained. If the problem persists, it would be necessary to replace the complete drive kit.

Q: Are dirt bike sprockets universal?
