If you have had your radiator guard punctured by a flying rock or tree branch, you will know that having to push your bike back to camp is no fun.
Avoid radiator damage by getting yourself a solid set of radiator guards! Radiator guards will deflect all oncoming debris and will stop expensive radiator replacements.
Here are my favorite dirt bike radiator guards available on the market right now.
#1 Devol Extreme Radiator Guards.
Devol Extreme are the radiator guards that I use on my WR250.


Pros
Simple Design – They come as a simple 2 piece kit.
Simple to Install – They wrap around the radiators without having to pull the radiators out of the bike and they mount securely to the frame. Nice!
Comprehensive Front and Side Protection.
Tough – They are made out of lightweight but tough aluminium alloy and NOTHING will get thru them.
Plenty of Front Ventilation – Cooling system won’t be affected.
Cheap! – They come in at only about 120 bucks!
A Huge range for many different makes/models of bikes.
Cons
none. They are great.

#5 How to Keep Your Dirt Bike Cooler.
If you are a low speed EnduroX rider or just want to keep your bike really cool, the above Trail Tech Radiator can also fit a radiator fan!

The fan unit sits behind the radiator and sucks air thru the radiator which will lower the temperature of your bike.
The fan unit bolts to the Trail Tech radiator guard and is either sold separately or as a kit (guards and fan).

What do you mean on some of the cons when you say limited range?
Hi Ryan. What I mean by ‘limited range’ is that they are only available for a limited selection of dirt bike makes and models. I’m going to update it though as it is a bit confusing now that you’ve pointed it out. cheers
