Types of Dirt Bike Chain

When you are going to buy some equipment for your dirt bike, you need to learn about them properly to get the right product suitable for your bike. Not only do you need to check for the quality of the product, but you also need to know the types and features that you need as well. For example, when it comes to dirt bike chains, there are two types of them. Therefore, you need to understand the types and know which one is suitable for your bike. The two types of bike chains are-

Types of Dirt Bike Chain

O-Ring Chain

O-ring chains are a type of chain that has rings separating the joints from coming in contact. These are shaped in O designs, and their main work is to protect the chain joins. One problem with these chains is that they cause a lot of friction to happen. When there is too much friction, it will reduce the power of the motorcycle and prevent it from running smoothly. But a lot of people prefer O-rings as it makes the chain more substantial and durable.

Unsealed Design

Unlike the O-ring chain, these unsealed designed chains do not cause friction, allowing the bike to run smoothly and with all the power manifested. This type of chain is suitable for most of the bike. One thing about these chains is that they need lubricants to work correctly. Another thing you need to check is the size of the chain to match your bike’s requirement.

How To Choose A Dirt Bike Sprocket

Choosing the right gear for your bike will provide you with a great outcome. Not only that your bike will be able to show its best performance, but you will also be able to ride with your utmost pleasure. One important gear for your dirt bike is the chains and sprocket. The quality and the ability of these gear will tell you how well the bike will perform on the field. Hence, you need to learn about them and choose the right one for your bike.

The first thing you need to do is to find the right sprocket for your bike. Next, you need to know what type of sprocket and chain will suit the bike and provide good quality. The type is the most crucial of all the factors as it will lead to the ultimate decision.

Of course, you need to look out for the quality as well. You do not want to buy something that has any less quality than other products. You need to see the description of the product correctly to get a clear idea about the quality.

Last but not least, sizing is also important. You need to see if the size you are buying is suitable for your bike or not. Whatever you buy, you always need to check if the product is good for your bike or not. You do not want to get an immediate replacement or want to change the product frequently.

Change Sprocket Size Increase Speed?

When it comes to the performance of dirt bikes, various myths are going around. But the question is, which myths are true and which are not! Definitely, all the myths are not going to work for everyone. But some of them can go well more than bad. One of the most asked questions is, does changing the sprocket of the bike increase speed?

Well, yes, it does, but you need to know the right way to do that. To increase your bike speed by changing the sprocket, you cannot just change according to your liking. Instead, it would be best if you made some calculated change. The rear sprocket of the bike should have a reduced size than the front sprocket. To increase the bike’s speed, you need a bigger front sprocket and a smaller rear sprocket.

By doing this, you can create more rpm for your bike than it was before. It happens as the larger front and smaller rear sprocket will lower the ratio for the bike and allow it to have a better speed than before.

Replace Chain and Sprocket

Owning a bike means you have the responsibility to take care of it and keep the maintenance in check all the time. If you want your dirt bike to work all the time correctly, nothing will beat owning the dirt bike up to date with all the necessary equipment. It is always better to do the repair or replacement work before the equipment gets into too bad condition.

Replace Chain and Sprocket

When it comes to chains and sprocket, you should always replace them before reaching their final stages. There are few ways to know when you need to change them. If you notice that that sprocket of your dirt bike has leaning teeth, cupping at the base, or tooth wear, these are signs that it needs a replacement.

And for the chain, if you see it developing a flat pattern, having rust, corrosion, and any other problem with the pins, you have to change them immediately. Another easy way to check is to see the distance between the nails, and if it is too much, that means there is some problem.

It is always better to change the gears that are interlinked with each other together. If you only change the chain, not the sprocket, then there is a chance that the chain will not be able to perform properly, and the durability will decrease due to the bad sprocket. So, change both of them together.

Considerations When Choosing The Best Dirt Bike Chain And Sprockets

Buying any product needs a lot of consideration. But when it comes to your bike gears, which are linked with the bike’s performance and your safety, you need to make sure that you are getting the best product by considering all the necessary facts when making the purchase.
When it comes to chains and sprockets, there are few things you need to keep in mind when finding the right product. Without these having in your mind, you will certainly not find the right product and use the money properly. The things you need to consider are-


The first thing you have to focus on is the type of chain and sprocket you want. We have already discussed the types of chains. Now you have to understand the features they are offering you and what will be the suitable one for your bike. After taking proper consideration, you can start looking for them.


Before everything, you should focus on the quality of the product. By quality, we meant the product’s material and how well it can perform for your bike. A good quality product will immediately bring many changes to your bike’s performance, and you will not have to worry about frequent replacement.


The last thing you should be worried about is the sizing. Although it might not be the most focused thing to consider, you still need to know the proper sizing of your bike. Without it, you will be more confused when replacing the chains and sprockets of your dirt bike.
