AMSOIL for Dirt Bikes
Use What the Pros Use!
Unsurprisingly, dual-sports and dirt bikes frequently operate in unfavorable off-road conditions, with ample low-speed stress punctuated by periods of high revving. Off-road racing adds frequent repetition between wide-open throttle on straights and rapid acceleration through corners. Throttling through jumps causes the rear tire to spin freely in the air, which creates a heavy load on the engine when it contacts the ground. Trail riding requires constant clutch and throttle manipulation to maneuver over and around obstacles.
Dirt bike engines are also inherently lightweight designs built for performance. However, removing mass and increasing power adds additional engine stress. Additionally, dirt bike pistons tend to have shorter piston skirts to reduce friction. Shorter pistons want to rock inside the cylinder, which concentrates tremendous force on the tiny contact area between the piston skirt and cylinder wall. Only a microscopic oil film provides protection in this area, so superior oil film strength is needed to help the engine survive. The combination of high rpm and lighter materials can quickly lead to dirt bike engine failure if the oil fails.
Making matters worse, many dirt bikes hold only about one quart of oil, which is tasked to protect all the engine and transmission components under these severe conditions. Therefore, most dirt bike riders change motor oil frequently. Under heavy use, dirt bike engines may even need to be rebuilt as often as every 15 hours.
AMSOIL Synthetic Dirt Bike Oil is engineered to enhance engine performance and reliability in extreme conditions, while delivering superior protection against engine wear. AMSOIL DOMINATOR® Synthetic 2-Stroke Racing Oil handles two-stroke dirt bike needs, and AMSOIL Synthetic Dirt Bike Oil is available in multiple viscosities for four-strokes as part of our complete dirt bike product line, including oil filters and AMSOIL Synthetic Dirt Bike Transmission Fluid.
AMSOIL Dirt Bike Oils
AMSOIL Synthetic Dirt Bike Oil is specifically engineered to provide superior clutch engagement an engine reliability in severe conditions, making it the best choice for professional riders and weekend warriors focused on improving performance on the trail or track. Whether launching the holeshot, roosting corners, overcoming obstacles or navigating tight turns deep in the woods, it delivers the performance attributes that dirt bike riders demand, including smooth, confident and consistent clutch engagement from start to finish.
- Delivers confidence in clutch feel
- Superior protection against gear wear
- Outstanding shear stability for long-lasting performance
AMSOIL Motorcycle Filters
AMSOIL Motorcycle Oil Filters are made from full-synthetic mediaand trap and hold more contaminants than other filters. They last longer, stop smaller dirt particles and offer reduced restriction for maximum engine performance and protection. Available in black or chrome.
AMSOIL Synthetic Dirt Bike Transmission Fluid
AMSOIL Synthetic Dirt Bike Transmission Fluid is specifically engineered to provide smooth, confident and consistent clutch engagement for predictable power delivery when riders need it most. It also guards against gear and clutch wear, making it the best choice for professional riders and weekend warriors focused on reducing maintenance so they can spend more time on the trail or track. As a high-performance alternative to original equipment manufacturer (OEM) fluids, it provides superior clutch engagement that resists slipping, grabbing and fading so riders can earn more holeshots with faster launches and easily maneuver over or around obstacles.
- Delivers confident clutch feel
- Protects against gear and clutch wear
- Helps prevent slip or grab
AMSOIL DOMINATOR® 100% Synthetic 2-Stroke Racing Oil
Racers can’t win what they don’t finish. That’s why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. These engines operate on the edge, yet reliability is critical. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.
- Excellent film strength for high-heat, high-rpm engines
- Anti-friction formula for maximum power
- Burns clean; helps prevent ring sticking and plug fouling
- Protects coated and non-coated racing pistons
AMSOIL Shock Therapy® Suspension Fluids
Formulated for Fade-Free Dampening and Smooth Rebounds in High-Performance Applications
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, and developed for those who demand top performance from their suspension systems.
