When riding dirt bikes off-road on trails, scratches, dings, stains and general overall wear and tear are to be expected.

But there are also parts in your dirt bike that need to be protected. One of these is theexhaust pipe, especially if you ride a 2-stroke. And the best way to protect it is to get a dirt bike pipe guard.

A dented exhaust pipe not only makes your dirt bike look older but more importantly it can affect the overall performance of your bike.

Next, we will tell you what type of pipe guards are available and help you to find the dirt bike pipe guard that best suits your riding style.

What Is a Dirt Bike Pipe Guard?

A pipe guard is a cover that is mounted on the exhaust pipe of the dirt bike. It protects the head pipe from dents and dings from ground debris and rocks and keeps its performance. In addition, many pipe guards include a heat shield that protects riding pants and boots from heated exhaust pipes.

The exhaust pipe is a fairly expensive part and it can easily be dented or twisted when dropping the dirt bike. With a proper dirt bike pipe guard, you can extend the exhaust pipe’s life span.

Why Do I Need a Pipe Guard on My Dirt Bike?

If you ride off-road and on trails, you should should definitely protect your pipe with a dirt bike pipe guard. After all, you are constantly jumping over boulders, logs and tree trunks that can easily dent or crush metal.

If you have been able to avoid mishaps so far, consider yourself lucky. Eventually, the pipe on your dirt bike will get in close contact with an obstacle and have some damage.

And it’s not just about the looks of your dirt bike that you can protects with a pipe guard. A few dings probably won’t amount to much but large or multiple dents can decrease the power and obstruct the flow of air from the engine.

2-strokes with their large pipes are more prone to damage and dents. But the head pipe on 4-strokes can also be damaged if not properly protected. Replacing the exhaust pipe isn’t exactly cheap so a dirt bike pipe guard can save you big bucks. Also, time spent on service is always time away from riding.

You might notice that more advanced enduro riders may not have any protection. Their advanced riding style allows this because they are able to avoid dropping the bike or hitting the pipe into obstacles. But if you are not yet on that level, you will find it best to invest into a good pipe guard. Otherwise, you need to be prepared for denting and replacing your head pipe regularly.

2-Stroke Pipes

A dirt bike pipe guard is even more important for 2-stroke engines. The head pipe (sometimes also called the expansion chamber) in 2-strokes is large and hanging low and front. Thus, it is more prone to hitting logs and rocks.

2-stroke pipes can take a beating and the minor dents from ground debris don’t usually impact the performance. However, at some point riding on rocky terrain with logs and other obstacles will guaranteed result in a direct hit that will make a large dent on the pipe. This is the case especially with the more aggressive riders.

After these kind of hits, your pipe will eventually be damaged so severely that it inhibits the performance. This means that you will need to either buy a new one or get the pipe repaired. At the latest at this point, most riders usually realize that the exhaust pipe needs protection.

4-Stroke Pipes

If you have a 4-stroke dirt bike, you don’t necessarily need a dirt bike pipe guard because the pipe sits much higher. Therefore, you should not have major issues unless you’re extremely unlucky.

4-stroke head pipes are not that prone to minor damage from rocks that kick up off the ground. However, impacts to boulders and logs can severely damage these smaller exhaust tubes.

Also, the super heated head pipe on a 4-stroke easily gets your riding pants and boots destroyed. There’s nothing more annoying than replacing the gear after each riding day. Dirt bike pipe guards for 4-strokes are mostly made of carbon fiber, which also functions as a heat shield.

Different Types of Pipe Guards

There are multiple different styles of dirt bike pipe guards available. Most of them are designed especially for 2-strokes since they encounter most issues with head pipes.

Most pipe guards are made of carbon fiber, composite materials, aluminum or steel. New generation pipe guards, such as the ones made of dual compound like stainless steel and elastomer, also emerge and gain popularity.

These all types of pipe guards mold around the head pipe of your 2-stroke or 4-stroke. The aluminum and steel pipe guards usually are smaller while the carbon fiber pipe guards are molded and fit around the entire head pipe.

A dirt bike pipe guard is very easy to install and doesn’t usually require removing the exhaust pipe. In general, a pipe guard can be mounted on the head pipe with ring clamps or pipe bands that come with the pipe guard itself. So you don’t need to buy them separately. But just in case, make sure that this is the case also with the pipe guard you buy. 

Carbon Fiber and Composite Pipe Guards

Dirt bike pipe guards made of carbon fiber and composite materials are very light and they excel in strength and damage control. All in all, they offer a great protection against dents and harder hits.

Pipe guards made of carbon fiber and composite materials are molded to fit perfectly on the head pipe. They are mounted on the pipe with brackets and/or clamps that securely hold the pipe guard in place.

In addition, they are quieter compared to the aluminum and steel pipe guards as they do not rattle against the steel or titanium pipe.

Carbon fiber composite pipe guards are usually made of a mix of carbon fiber, kevlar, fiberglass and high-temperature resins. This gives them a high impact strength. They often serve also as a heat shield.

If you have a 2-stroke, you may need to occasionally remove the carbon fiber pipe guard for cleaning. The reason for this is that sometimes sticks, small rocks and other debris work their way in between the head pipe and the pipe guard, which can cause scratching.

Aluminum and Steel Pipe Guards

Dirt bike pipe guards made of aluminum and steel generally are less expensive options. But they are smaller so they sometimes may lack in fully protecting the entire head pipe.

Aluminum and steel pipe guards are in general stronger and heavier compared to the carbon fiber versions. They can be bent and fitted to the curves of the pipe if needed. However, for the same reason, they can bend in contact while carbon fiber would have to break or be punctured.

Aluminum and steel pipe guards tend to rattle and make more noice than carbon fiber pipe guards. However, you can try to minimize the rattling and scratching of the pipe. For example, you can use small beads of silicone on the inside of the pipe and allowed them to dry before installing.

Aluminum and steel pipe guards are stiffer and they take a bit more effort to install. In addition, it stands out more than the carbon fiber pipe guard.

Conclusions

Installing a pipe guard on your dirt bike is essential especially if you ride off-road and on trails.

This applies both to 2-strokes and 4-strokes even though a pipe guard is even more important on a 2-stroke due to the shape and construction of the head pipe that is more prone to hits.

Dents on a head pipe are inevitable when riding on trails and enduro. They do not look good and they can rob power and create heat. A pipe guard saves you money and time since you don’t need to regularly replace your head pipe.

If you don’t yet have a dirt bike pipe guard make sure to get one before your head pipe gets dented or worse.
