V-twin and Cruiser Bikes

Motorcycle Oils for V-Twin Cruiser Motorcycles

Large-displacement, air-cooled, low-revving V-twin and Cruiser bikes run notoriously hot, placing unique and stringent demands on the lubricants that protect them. AMSOIL Synthetic Motorcycle Oil ensures cool operation and reliable protection and performance both on the open road and in stop-and-go traffic.

AMSOIL Synthetic V-twin and Cruiser Bike Lubricants are formulated to keep hot-running V-twin and cruiser bikes running cool and operating at peak performance, whether cruising down the highway or showing off your ride at the rally.

AMSOIL Synthetic V-twin Motorcycle Oil is engineered to protect critical components in high-heat conditions. It exceeds the standard for high-temperature film strength to deliver excellent wear protection and contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions.

AMSOIL Synthetic V-twin Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to breakdown and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

AMSOIL V-Twin Motorcycle Synthetic Oil Change Kit with Oil Filter

In 2015, AMSOIL expanded its already extensive line of Synthetic Cruiser Bike Oils by adding 3 new products specifically designed for V-twin Motorcycles.

*AMSOIL SAE 20W-40 Synthetic V-Twin Motorcycle Oil is specifically formulated to provide premium protection for Victory and model-year 2013 and newer Indian motorcycles. It is the only full-synthetic 20W-40 motorcycle oil on the market, presenting riders a premium alternative to Indian- and Victory-branded semi-synthetic oils.

Indian and Victory motorcycles incorporate a shared sump, and AMSOIL 20W-40 oil is formulated to provide outstanding protection for engines and transmissions. It is absolutely shear stable, keeping motorcycles well-protected even in extreme heat conditions. AMSOIL 20W-40 oil can be used in any motorcycle that requires SAE 20W-40 motorcycle oil.

AMSOIL Synthetic V-twin Motorcycle Oil is now also available in a SAE 15W-60 and a SAE 60 viscosity.

*AMSOIL V-Twin Synthetic Primary Fluid and *V-Twin Synthetic Transmission Fluid are purpose-built for bikers who prefer a dedicated Primary Chaincase Lubricant and a dedicated Transmission Fluid over a multi-use lubricant.

V-Twin Synthetic Primary Fluid is formulated with a balanced additive system that provides consistent clutch performance and feel. It helps riders easily find neutral and promotes smooth acceleration, whether in stop-and-go city conditions or when on the highway. Its superior load-holding capacity helps prevent clutch slip for confident takeoffs.

V-Twin Synthetic Transmission Fluid promotes formation of a durable oil film on bearings and gears, helping to dampen loud thunks when shifting and reduce gear noise. Its frictional properties deliver smooth shifts and help quiet transmission noise, letting riders focus on enjoying the ride.

Factory Fill for Erik Buell Racing

There is no question that legendary superbike builder Erik Buell appreciates quality and performance. His pioneering attitude and commitment to American ingenuity mirror the values of AMSOIL INC.

Fittingly, Buell chose AMSOIL Synthetic Lubricants as the Factory-Fill and primary service-fill recommendation for his Erik Buell Racing (EBR) bikes. AMSOIL is also the Official Oil of the EBR team in the AMA Pro SuperBike Series and World Superbike.

Eric Buell believes AMSOIL products can save you thousands of dollars in engine wear. "Instead of having to redesign the engine, I just had to use a better-quality oil." - Erik Buell

AMSOIL is proud to support the efforts of EBR to deliver uncompromising performance for sport-bike riders on and off the track.

Dirt Bikes

AMSOIL Synthetic Dirt Bike Lubricants are engineered to deliver the performance attributes most requested by on- and off-track dirt bike riders.

AMSOIL Synthetic Dirt Bike Oil's superior friction-durability properties help maximize clutch life and minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. It also withstands high-rpm operation, extreme heat and mechanical shear, offering superior protection against gear, bearing and piston wear.

Dirt Bike Oils, Fluids, Lubes and Filters

AMSOIL Synthetic Dirt Bike Lubricants are formulated for exceptional protection and performance in extreme operating conditions, reducing maintenance, extending equipment life and, most importantly, keeping you out of the garage and on the trail.

You drive your bike hard – on the trail, on the racetrack and on the back 40. You don’t have time for a breakdown. AMSOIL Dirt Bike Oil delivers the confidence and performance you need to get on it and get out front.

Dyno Tested

Protection against extreme heat is of the utmost importance in motorcycle applications. The air-cooled V-twin engines used in Harley-Davidson motorcycles can get extremely hot, particularly when idling or traveling at low speeds. If motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised.

AMSOIL Synthetic Cruiser Bike Oil is formulated to withstand extreme heat conditions beyond the hottest temperatures motorcycles typically experience, providing peace of mind that motorcycles receive outstanding protection and performance no matter how extreme the operating conditions.
