Regardless of whether you own a dirt or motocross bike, it requires considerable volumes of clean, fresh air to ensure efficient combustion. Your motorcycle’s air intake equipped with a filter is designed to carry out the task of routing and cleaning the oncoming airflow so that the motor’s combustion chambers would be supplied with the needed amounts of oxidizer. You can drop your motorcycle while you are riding across dells, hopping over dunes, or crossing riverbeds, resulting in the need to replace the damaged or outright broken intake parts or worn out filter media.

Fortunately, there are plenty of replacement parts and accessories available in our online store. You can use them to restore your bike to its like-new condition. Our dirt bike air filters and intakes are designed to clean the flow from such debris as sand, grit, dust, insects other contaminants to allow the motor to perform as required while breathing easily. Such components are produced using robust, durable plastics and metals, featuring synthetic and paper media that can surpass many O.E. characteristics. The aforementioned parts are supplied by such reputed companies as Boyesen, Moto Tassinari, Carbon Tech, K&N, and many others, so you can be sure to get a premium-quality product.
