Radiators are one of the most crucial components for your bike — as the main cooling system on board, it’s essential for keeping your bike running. However, it’s often susceptible to damage due to its location on the bike. Positioned behind the front fender and in between the side shrouds, it’s in a vulnerable spot for such an important piece of equipment. And even without the risk of damage, it’s a delicate component of your dirt bike; if it fails and causes overheating, it can create serious problems and damage, some of which can be potentially a risk to your safety as a rider and could possibly leave you stranded if you’re out on the trails.
If you’re a dirt bike rider, you should be very aware of just how important the radiator component is to ensure you have a safe ride and make it home. It’s no surprise then, that one of the most common aftermarket investments for riders is a motorcycle radiator protector. A high-quality protector will offer additional coverage, support and rigidity for your dirt bike’s radiator, rendering it less susceptible to damage while also helping it keep cool and preventing overheating. Effective dirt bike radiator guards will also help keep the radiator ridged and more protected in case you drop the bike.
Prevention is always better than a cure, so investing in a good motorcycle radiator protector can also help you save money in the long run. The cost of replacing a radiator — or even the bike itself — can be far more expensive than simply investing in protective gear. So keep your bike safe by investing in effective radiator protection from B&B Offroad Engineering. We stock some of the best dirt bike radiator guards in the country, as well as online oil cooler guards to ensure the longevity of your bike and your safety while you ride.

Radiator Guards: Essential Protection for Peak Bike Performance
Your motorcycle’s radiator guards play a critical role in engine cooling, ensuring that your bike operates efficiently without overheating. However, the radiator is highly vulnerable to damage from flying debris, rocks and unexpected impacts, especially in off-road or adventure riding conditions.
Without a durable radiator guard, you risk coolant leaks, leading to rapid overheating and engine failure. The bends or cracks in the radiator fins can reduce cooling efficiency and increase wear.
At B&B Off Road Engineering, our radiator guards provide superior protection without compromising airflow, ensuring optimal cooling performance for riders. The radiators are made from high-strength aluminium for superior impact resistance. The precise laser-cut designs maintain airflow and prevent overheating.

Frequently Asked Questions
Why do I need a radiator guard for my dirt bike?
A radiator guard protects your cooling system from debris, impacts and crashes. Off-road conditions expose radiators to rocks, mud and branches, making them prone to damage without a protective shield.
Will a radiator guard affect my bike’s cooling performance?
No! Our radiator guards are engineered with airflow-optimised designs, ensuring your engine stays cool without blocking ventilation. Our guards allow uninterrupted airflow for peak cooling efficiency.
Are your radiator guards compatible with all bike brands?
Yes! We manufacture KTM, Yamaha, Honda, Suzuki, Husqvarna radiator guards and more. Each guard is designed to match specific bike models, ensuring perfect fitment without modification.
What’s the difference between a radiator guard and a radiator brace?
- Radiator Guards – Shield the front surface of the radiator, preventing rocks, mud and debris from causing damage.
- Radiator Braces – Provide side reinforcement, preventing the radiator from bending or cracking under stress.
How difficult is it to install a radiator guard or brace?
Our radiator guards and braces are designed for simple, bolt-on installation, requiring basic tools and no modifications. Installation can vary but usually can be done within an hour or less.
