AMSOIL Dirt Bike Products Maximize Performance of Bike and Rider

Whether you ride to take the checkered flag or conquer the trails near home, AMSOIL has you covered.

Most dirt bike riders have one goal in mind when they hit the track or trail: ride faster and more effectively. Clutch performance goes a long toward ensuring you get out front and stay out front. Clutch slippage or inconsistent clutch feel can lead to poor starts out of the gate, while maneuvering around obstacles on the trail increases the opportunity for clutch slippage if low-quality lubricants are used.

Consistent clutch feel important

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.

Don’t overlook chain and fuel maintenance
Although easy to overlook, the chain is another important area to maintain. In order to ensure optimum performance and life, dirt bike chains require premium lubrication and protection against dirt, mud, water and constant stress. AMSOIL Chain Lube doesn’t fling off, helping you avoid the hassles of frequent reapplication and the stresses of worrying about chain durability.

Degraded fuel presents major problems for dirt bike engines. It can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons, causing pre-ignition, rough idling and poor throttle response. AMSOIL Quickshot® is formulated to thoroughly clean and restore peak performance in dirt-bike fuel systems. Its revolutionary technology addresses problems associated with ethanol, water and dirty pump gas.

Racing is Reseach™
AMSOIL corporately sponsored supercross and motocross racers identified consistent clutch feel as a key performance attribute. Consistent clutch feel is critical to motocross riders during starts to keep the bike from lurching forward prior to the gate dropping. Trail riders, meanwhile, need consistent clutch feel to confidently navigate obstacles without having to shift gears and lose momentum.

Shear Stability
High-revving dirt bikes can tear apart the molecular structure of motor oil, resulting in viscosity loss. Most four-stroke bikes use a shared sump that supplies oil for the motor, transmission and primary chaincase. Transmission gears can cause shear-induced viscosity loss if inferior oils are used. Oil that has lost viscosity can fail to develop a strong lubricating film on metal components, leading to wear. AMSOIL Synthetic Dirt Bike Oil’s durable synthetic base oils naturally resist viscosity loss due to mechanical shear.

Protects Gears Against Wear
By retaining its viscosity despite high heat and shearing forces, AMSOIL Synthetic Dirt Bike Oil guards against gear wear for maximum component life, helping riders get the most out of their bikes.

Replaces More Expensive Oils
AMSOIL Synthetic Dirt Bike Oil is a high-performance replacement for more expensive, imported OEM-branded oils.

Revised Recommendations
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
