Prepare Your Bike for Summer Riding
Motorcyclists are gearing up for another summer of rallies, road trips and dirt riding. Whether you’re into V-twins, metric, or dirt bikes, prepare your bike for a long summer riding season with fresh oil that is dialed-in to meet the specific needs of your motorcycle.
Powerful, hot-running V-twins generate intense heat, especially in slow-moving rally or parade traffic. Air-cooled bikes rely on a steady flow of air over the cooling fins to keep the engine cool. Stop-and-go riding and extended idling on hot summer days can quickly cause the engine temperature to skyrocket. If the motor oil cannot withstand the intense heat and powerful mechanical action inside a V-twin engine, the oil loses viscosity and its ability to provide adequate engine protection.
Bikes that use the same oil for both the engine and transmission are especially prone to viscosity loss. AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable and does not thin from mechanical activity, so it’s excellent at protecting your V-twin engine against wear.
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 parts of your bike. It is available in 20W-40, 20W-50, 15W-60 and SAE 60 as part of our complete V-twin product line, including complete oil change kits with filter. For bikers who prefer to use oils formulated specifically for the transmission or chaincase, AMSOIL Synthetic V-Twin Transmission Fluid and Synthetic V-Twin Primary Fluid are engineered to the same exacting standards.
The metric motorcycle market includes standard (naked), cruiser, adventure (ADV), touring and sport bikes
High-performance sport bikes need wet-clutch-compatible lubricants that deliver efficient and consistent shift performance. The high speeds and rpm these bikes are capable of can also cause inferior oils to foam, which decreases the lubricant’s ability to protect the engine.
Like sport bikes, standard and cruiser motorcycles are also defined by engine power and responsiveness, so smooth shifting and reliability are important traits. Touring bikes aim to provide comfort, luxury and the adventure associated with long, cross-country trips, which also benefit from extended drain intervals.
Our advanced synthetic technology maximizes engine responsiveness and delivers excellent wet-clutch compatibility, enabling smooth shifts for a more comfortable ride. By controlling foam, AMSOIL Synthetic Metric Motorcycle Oil helps you confidently push your bike to its redline, for maximum speed, acceleration and cornering ability. Its outstanding resistance to extreme heat provides peace of mind, knowing your bike will provide trouble-free operation mile after mile.
AMSOIL Synthetic Metric Motorcycle Oil enhances performance and reliability and delivers superior protection against engine wear in high-performance engines.
It is available in 10W-30, 10W-40 and 15W-50 as part of our complete metric motorcycle product line, including oil filters and AMSOIL Powersports Antifreeze & Coolant. It also extends drain intervals up to twice the bike manufacturer’s recommendations, allowing riders to confidently wander far from home.
Unsurprisingly, dual-sport and dirt bike operating conditions are more like that of an ATV or UTV. True, you don’t plow snow with your motorcycle, but the bike undergoes ample low-speed stress punctuated with periods of high revving. When racing, there’s frequent repetition between wide-open throttle on the straights and rapid acceleration through the corners. Throttling through jumps causes the rear tire to spin freely in the air, then create a heavy load on the engine when it contacts the ground. And trail riding requires lots of clutch and throttle manipulation to maneuver over and around obstacles.
Dirt bike engines are typically lightweight designs meant for performance. Any time you remove mass and increase power, you increase engine stress. The combination of high rpm and lighter materials creates the perfect scenario for engine failure if the motor oil fails to do its job.
Additionally, dirt bike pistons tend to have shorter piston skirts to reduce friction, which doesn’t help engine longevity. A shorter piston wants to rock inside the cylinder, which concentrates tremendous force on the tiny area where the piston skirt and cylinder wall contact. Only a microscopic oil film provides protection in this area, superior oil film strength is needed to help the engine survive.
Making matters worse, dirt bikes barely hold any oil, often only about one quart. That single quart of oil must fight wear, resist heat and prevent deposits, which is why most dirt bike riders change motor oil frequently, and in heavy use, the top-end may need to be rebuilt as often as every 15 hours!
AMSOIL Synthetic Dirt Bike Oil enhances engine performance and reliability, delivers superior protection against engine wear, and is far less expensive and less hassle than rebuilding your top-end. DOMINATOR® Synthetic 2-Stroke Racing Oil will handle all of your two-stroke needs, and oil for four-stroke dirt bikes is available in 10W-40, 15W-50 and 10W-60 as part of our complete dirt bike product line, including oil filters and AMSOIL Synthetic Dirt Bike Transmission Fluid.
No matter what you ride, AMSOIL offers premium synthetic lubricants designed to address the specific and challenging demands of powerful, high-revving engines, making every ride confidence inspiring.
