Every system of your motorcycle and its parts should be in good working condition. And the cooling system with its thermostat, water pump, hoses, and a radiator cap are no exception. It is extremely crucial to have a properly functioning radiator cap. The radiator cap helps protect your radiator from overheating and prevents fluid loss. Intended to hold a certain amount of pressure in the cooling system and to dump the pressure when it exceeds the predefined level, the radiator cap can help avoid many cooling problems. So, if you have a damaged or worn out radiator cap, do not put off its replacement.

On our online shelves, we’ve gathered a significant selection of premium radiator caps and covers from trusted and experienced brands like Outlaw Racing, CV4, K&L Supply, Twin Air, Fire Power, etc. They design their products with the highest precision and superior craftsmanship and use the finest grade materials and most up-to-date equipment to reach the unsurpassed level of quality, safety, and efficiency. Apart from functionality, we also think of aesthetics and provide many eye-catching radiator cap covers. Available in different styles and colors, they are a fine way to dress up the engine compartment of your motorcycle without compromising the accessibility of the cap.

On our website, we provide both replacement and performance radiator caps. The performance radiator caps allow for running a higher water system pressure and higher boiling point. We also offer first-rate radiator caps with temperature gauges. They provide an accurate temperature reading of your coolant and show whether the temperature to open the radiator cap is safe or not. So, whatever radiator cap you may need or want, we have you covered with many high-grade options that will help you solve the recurring boil-over problem and will keep your coolant where it belongs - in the radiator, ensuring safe and efficient operation of your bike for years.
