Keep the engine and gearbox like new and perform the way it was designed. All it takes is AMSOIL in your dirt bike at your next service.

What is the best protection for the trail or track?

Riders everywhere agree about the AMSOIL brand

AMSOIL Synthetic Dirt Bike oil delivers the reliable, constant clutch feel and wear resistance to protect their bikes best. Regardless of the brand – KTM, Yamaha, Husqvarna, Honda – it’s the oil they trust to prevent clutch wear, maintain the clutch feel, and protect their engines.

In on-track testing, our dirt bike oil dramatically reduced the wear on clutch plates after twice as many starts as the leading OEM oil. Anti-wear properties and the uniform molecular structure from our synthetic base oils inhibit wear on gears, bearings, and pistons. And with lower friction, horsepower can be used to its full potential. Whether it’s for recreation or professional racing, the benefits are no small thing.

The AMSOIL difference

Unlike other manufacturers, AMSOIL Synthetic Dirt Bike Oil is specifically formulated for track and trail-ridden dirt bikes. Although AMSOIL Motorcycle Oil is more than sufficient to handle the tough-as-nails conditions you’ll put your dirt bike through, AMSOIL’s unique dirt bike formula targets wet clutch performance even more accurately. That’s something you won’t find on shelves anywhere else.

Worried about warranty implications? AMSOIL keeps the factory warranty intact regardless of brand, and users are also backed by the AMSOIL Limited Warranty. So go ahead. dump the clutch. We’ve got you covered.

Why is our dirt bike oil different?

Our customers have asked: “I have always used AMSOIL 10W40 motorcycle oil in my dirt bike with good results. Is there any reason to switch to oils for dirt bikes?”

AMSOIL Technical highlights that although their synthetic motorcycle oil is suitable for dirt bikes, their synthetic dirt bike oil is specifically formulated to meet the needs of four-stroke dirt bikes, such as providing a clutch feel along with metal protection that’s dialed in for dirt bike riders. And if you need something more geared towards the needs of hot-running on-road v-twin motorcycles, we’ve got that too with AMSOIL synthetic motorcycle oil.
