AMSOIL Dirt Bike Products Maximize Performance of Bike and Rider

The tradition of innovation and technological advancement continues with AMSOIL synthetic lubricants for dirt bikes. Hours of testing in AMSOIL chemical and mechanical labs resulted in lubricants engineered to maximize your bike’s performance on the trail and at the track. Testing with professional teams in Monster Energy Supercross, AMSOIL Arenacross and AMSOIL GNCC helped further fine-tune AMSOIL Synthetic Dirt Bike Oil for outstanding wear protection and consistent clutch feel. 

AMSOIL Synthetic Dirt Bike Oil delivers the confidence and performance you need to get on it and get out front.

Confidence in Clutch Feel

AMSOIL Synthetic Dirt Bike Oil’s superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when navigating the trail. In an extreme simulated-start test, AMSOIL Synthetic Dirt Bike Oil continued to deliver consistent clutch feel following 32 simulated race starts, while a leading manufacturer’s oil demonstrated inconsistent clutch-lever action and poor clutch feel after 16 starts. AMSOIL Synthetic Dirt Bike Oil’s superior performance helps instill in riders the confidence that their bikes will perform consistently in all types of riding conditions. It also delivers superior wear protection for engine and clutch components.

Some riders, however, prefer a dedicated transmission fluid instead of a multi-purpose motor oil. For them, AMSOIL Synthetic Dirt Bike Transmission Fluid features a wet-clutch-compatible formulation designed to prevent clutch slippage and deliver consistent, confident clutch feel. It helps you ride smoother and faster for maximum performance. It also provides excellent wear protection for gears and clutch plates, reducing time and money spent on maintenance.

Protects Against Wear 

AMSOIL Synthetic Dirt Bike Oil withstands high-rpm operation, extreme heat and mechanical shear. Its synthetic base oils naturally resist viscosity loss and provide a protective film against wear to gears, bearings and pistons. Its anti-wear additives provide an extra measure of protection, promoting long component life to help riders get the most out of their bikes.

Synthetic Oil
Engineered to deliver the performance attributes most requested by on- and off-track dirt bike riders, including consistent clutch feel. Consistent clutch feel is the result of “friction durability,” so whether deep into a race or deep in the woods, riders can feel confident their clutch will perform from start to finish.

Synthetic Suspension & Transmission Fluid

Shock Therapy® Suspension Fluid
A properly functioning suspension is vital to performance during a race or maneuvering around obstacles on the trail. For greatest effectiveness, riders need consistent suspension feel over a broad temperature range. Aggressive riding, however, can heat suspension fluid enough to cause viscosity loss, resulting in soft, inconsistent feel. AMSOIL Shock Therapy Suspension Fluid resists viscosity loss over a broad temperature range for consistent, effective suspension feel. It reduces foaming, aeration and wear, while conditioning seals for maximum life.

Dirt Bike Transmission Fluid SAE 80

If you are currently satisfied using AMSOIL Synthetic Dirt Bike Oil in your dirt bike transmission, there’s no need to change anything. However, Synthetic Dirt Bike Transmission Fluid is now the primary recommendation for all two-stroke bikes, since two-strokes use a separate sump. Many two-stroke riders look for lubricants labelled specifically for the transmission, and this adjustment is designed to suit their needs.

The four-stroke market segment is slightly different. The popular Honda* CRF is the only four-stroke bike that uses a separate sump, but because the owner’s manual recommends using the same oil in the engine and transmission, AMSOIL Synthetic Dirt Bike Oil remains the primary recommendation. Synthetic Dirt Bike Transmission Fluid is the secondary recommendation.

For all other four-stroke bikes, AMSOIL Synthetic Dirt Bike Oil is the primary – and only – recommendation. For specific product recommendations, consult the Motorcycle Product Guide on
