In this article, I will provide a comprehensive review of Enduro Engineering radiator guards. I will cover key features, installation process, and performance details after a trail test.

Enduro Engineering is a reputable brand in the off-road industry, offering a range of high-quality parts and accessories for dirt bikes. Their strong, yet light weight aluminum braces are specially designed to provide maximum protection for your radiator without sacrificing airflow.

Next, let’s dive into this hands-on Enduro Engineering radiator braces review.


The installation process is relatively straightforward and can be accomplished by anyone with basic mechanical skills. Each guard comes with a set of instructions that are easy to follow and understand. The guards attach to the existing mounting points on your dirt bike’s radiator. All necessary hardware is included in the package.

The installation process is simple and should take less than 10 minutes. Basically, you will only need a socket set or similar to properly install the guards. And, once installed, the guards offer a snug fit and will not rattle or vibrate during use.

Overall, the installation process is easy and hassle-free, making it a great option for riders who want to add an extra layer of protection to their dirt bikes.

Protection and Fitment

One of the main benefits is the increased protection they provide against rocks, stick, mud, and other debris of your dirt bike’s radiator.

Another common damage is direct side impact damage to the radiator. Also, this usually happens by dropping the dirt bike over on either of its sides. Additionally, this direct side hit will typically twist or push the radiator inwards and bending the outer side of the radiator causing coolant leaks. However, these guards will prevent damage in all these above mentioned scenarios.

The lower flap on the left side radiator gets very close to the exhaust expansion chamber.

The only concern I have with the fitment, is on the left side radiator. The lower flap is about quarter of an inch away from hitting the 2 stroke pipe. I wonder how this will work when I eventually bend the pipe inwards or upwards. Remains to be seen.

The outer sides extend to cover the radiator very well. They also fit closely to the radiator and leave the inside open. This means you can install a dirt bike radiator fan with brackets on the right side radiator.

In our testing, we found that these radiator braces held up extremely well against rocks and debris on the trails. Meanwhile, even after multiple impacts, the guards showed no signs of bending or cracking, and the radiator remained completely protected.

Overall, these guards offer outstanding protection and durability, making them a great investment for any dirt bike rider.

Durability and Performance

One of the concerns riders often have with braces is that they may reduce the airflow to the radiator. Poor airflow could potentially lead to overheating and reduced engine performance. However, they are designed to allow for maximum airflow while still providing complete protection for your radiator.

In our testing, we found that using these guards did not have any noticeable effect on the cooling of our dirt bike. The bike ran smoothly and did not experience any overheating issues, even during long rides in hot weather.

Overall, the radiator braces provide excellent protection for your radiator without sacrificing performance or airflow, making them a great choice for riders who want the best of both worlds.

Style and Aesthetics

In addition to providing top-notch protection and performance, they also add a touch of style to your dirt bike.

The guards are available in aluminum or black to match your bike’s color scheme. Their sleek and minimalist design gives your bike a clean and modern look.

I like the thick aluminum look and fit. The guards seem like factory made and in my mind makes the dirt bike better looking. They also fit into Acerbis aftermarket plastics kit, which is a plus.
