Don’t Just Choose Any Oil. Make it Official.
The superior protection and performance of AMSOIL Synthetic Motorcycle Oil is recognized by the largest and most influential motorcycle rallies in the nation. The Sturgis Motorcycle Rally, Daytona Bike Week and Laconia Motorcycle Week all proudly feature AMSOIL as their Official Oil. AMSOIL shares your passion for riding. From the kickoff to the motorcycle season in Daytona to the City of Sturgis Motorcycle Rally in August, AMSOIL is proud to lend its support to the motorcycle lifestyle.
There is nothing quite like jumping on a big V-Twin and hearing that rumble. The fresh air and freedom to go anywhere you choose bring unmatched satisfaction. Nothing kills that feeling faster than a noisy transmission or an overheated bike. AMSOIL V-Twin products are engineered to address the specific demands of V-Twin motorcycles. Advanced synthetic technology protects your bike and the spirit of the American biker.
The classic air-cooled V-twin engine found in most Harley-Davidson motorcycles gets extremely hot. For example, cylinder temperatures reached 420ºF (216ºC) in AMSOIL’S in-house dyno testing. Heat that intense wreaks havoc on cheap motor oil, causing it to lose viscosity and become thinner, effectively turning a 20W-50 into a 10W-40, or worse. Running an engine on a lighter viscosity than it is designed for increases the risk of internal engine wear.
Extreme heat also hastens chemical breakdown, as the rate of oxidation doubles for every 18ºF (10ºC) increase in oil temperature. That means for every 18ºF increase in temperature, oil life is cut in half. It’s imperative that the oil in an air-cooled V-twin can withstand such intense heat. AMSOIL Synthetic V-Twin Motorcycle Oil is formulated with synthetic base oils that maintain viscosity at these extreme temperatures.
Bikes that use the same oil for both the engine and transmission are especially prone to viscosity loss, as the force of shifting gears can also destroy the oil’s molecular structure. AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable and does not thin from mechanical activity, providing reliable protection against wear under the toughest riding conditions.

AMSOIL Synthetic V-Twin Motorcycle Oil delivers excellent performance in the engine, transmission and primary chaincase, offering the convenience of a single oil for all three reservoirs. It is available in multiple viscosities as part of our complete V-twin product line, including complete oil-change kits with filter. For bikers who prefer specifically formulated oils, AMSOIL Synthetic V-Twin Transmission Fluid and Synthetic V-Twin Primary Fluid are engineered to the same exacting standards.
AMSOIL 100% Synthetic V-Twin Motorcycle Oil
AMSOIL Synthetic V-Twin Motorcycle Oil is a premium oil designed for those who demand the best protection for their motorcycles. It is the result of extensive research and is specially formulated to excel in all areas unique to motorcycles, including the high temperatures of air-cooled engines such as Harley-Davidson* V-twins, wet-clutch lubrication, extreme-pressure regions of gears and chains and rust common to short trips and storage. AMSOIL Synthetic V-Twin Oil is multi-functional and fulfills the requirements of both domestic and foreign motorcycles.
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 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.
