Why Choose AMSOIL for Your Motorcycle
AMSOIL Motorcycle Oils are formulated to protect engines and transmissions in motorcycles, even under the most extreme conditions. The full lineup of AMSOIL synthetic motorcycle oils is recommended for on-road and off-road bikes alike, delivering long-lasting wear protection and extending engine life while reducing maintenance costs.
AMSOIL motorcycle oils come in a wide range of formulations and viscosity grades. Harley-Davidson and other big-twin riders run our 20W-50 V-twin synthetic oil (or grab a complete V-twin oil change kit with filter), while sport-bike riders match a 15W-50 synthetic metric oil to their owner manual. Off-road riders pick a dirt-bike grade like 10W-40 synthetic dirt bike oil for clean clutch feel and consistent shifting.
Whether you ride a cruiser, touring bike, sportbike, dirt bike, or scooter, AMSOIL builds a motorcycle oil to keep your engine and transmission running at peak performance. Use the year-make-model motorcycle oil lookup guide to find the exact AMSOIL recommendation for your specific bike.
