Why riders choose AMSOIL

Motorcycles are hard on lubricants. Air-cooled V-twins build heat. Wet-clutch sport bikes shear oil. Dirt bikes punish gears and clutches. Scooters often combine engine, gearbox and daily stop-and-go use in a compact package. AMSOIL makes sense for riders because the lineup is not one-size-fits-all. It is split into dedicated motorcycle oils, primary and transmission fluids, filters, brake fluid, coolant, chain care, fuel-system products and cleaning products so you can build a complete maintenance routine around your exact machine.

That matters whether you ride a Harley-Davidson Road Glide, Indian Scout Bobber, Honda Gold Wing, Yamaha MT-07, BMW R 1250 GS Adventure, Triumph Tiger 900 GT Pro, Kawasaki Ninja ZX-6R, Suzuki V-Strom 650, Honda PCX 160, Yamaha XMAX 300, Vespa GTS, Kymco Xciting, Honda CRF450R, Yamaha YZ450F, KTM 450 SX-F, Husqvarna FC 450, KTM 300 XC-W or Yamaha YZ125.

V-twin motorcycles

AMSOIL supports popular V-twin applications including Harley-Davidson touring and cruiser models, Victory motorcycles, and Indian models including Chief and Scout applications.

V-twins often run hot, spend time in traffic, and put heavy demands on the engine, primary and transmission. AMSOIL offers riders two approaches: a convenient all-in-one choice for many applications, or dedicated fluids for separate sumps when that fits the bike and the rider’s preference.

Core V-twin products

• 20W-50 100% Synthetic V-Twin Motorcycle Oil — a strong fit for many Harley-Davidson applications. It is built to handle high heat, resist viscosity loss, reduce wear and deposits, and for many Harley applications it gives riders the convenience of one lubricant for all three sumps.
• 20W-40 100% Synthetic V-Twin Motorcycle Oil — a key fit for many Victory models and many 2013-and-newer Indian motorcycles. It is engineered for high-heat operation, strong film strength and long-term wear control.
• 15W-60 100% Synthetic V-Twin Motorcycle Oil — an important option for Indian Scout applications.
• SAE 60 100% Synthetic V-Twin Motorcycle Oil — a valuable fit for older big-bore air-cooled Harley applications such as Knucklehead, Panhead and Shovelhead engines.

Dedicated V-twin sump fluids

• 100% Synthetic V-Twin Transmission Fluid — built for quieter operation, cleaner shifts and long transmission life in V-twin transmissions that do not share a sump with the engine.
• 100% Synthetic V-Twin Primary Fluid — designed for steady clutch performance, controlled engagement and easier neutral finding in V-twin primary chaincases.

V-twin maintenance notes

If you ride a Harley-Davidson Road Glide, Street Glide, Road King or other touring model, or an Indian or Victory cruiser, the lookup guide is the fastest way to confirm the correct oil, filter and any additional fluid needs for your exact year and engine.

Street, sport, touring and adventure motorcycles

AMSOIL supports a wide range of four-stroke metric motorcycles, including sport bikes, naked bikes, touring motorcycles and adventure bikes.

Popular fit examples

Honda Gold Wing
Yamaha MT-07
BMW R 1250 GS Adventure
Triumph Tiger 900 GT Pro
Kawasaki Ninja ZX-6R
Suzuki V-Strom 650

Why these oils work well

Street and adventure motorcycles often ask one oil to protect the engine, gearbox and clutch at the same time. AMSOIL’s metric motorcycle oils are built for that kind of shared-sump stress. They are made for wet-clutch compatibility, heat control, viscosity stability and internal cleanliness, which is exactly what riders want on daily commutes, weekend canyon rides, multi-state touring trips and loaded adventure routes.

Core metric motorcycle products

• 10W-30 100% Synthetic Metric Motorcycle Oil — for bikes that call for lighter viscosity without giving up motorcycle-specific protection.
• 10W-40 100% Synthetic Metric Motorcycle Oil — the backbone option for many street, touring and adventure bikes.
• 15W-50 100% Synthetic Metric Motorcycle Oil — a strong fit where the owner’s manual calls for a heavier hot-grade motorcycle oil.
• 5W-40 100% Synthetic Metric Motorcycle Oil — a useful option when cold-start performance and the correct manufacturer spec call for this viscosity.

Additional service items for many street and adventure bikes

Many touring and adventure motorcycles also require a filter, and some applications call for additional gear lube, transmission fluid, brake fluid or coolant service. That is one reason the lookup guide is so valuable. It can surface the full service list for motorcycles with shaft drives, DCT systems, final drives or separate gearcases.

Scooters

AMSOIL also supports four-stroke scooter applications.

Popular fit examples

Honda PCX 160
Yamaha XMAX 300
Vespa GTS
Kymco Xciting

Why scooter-specific oil matters

Scooters live in stop-and-go riding, run compact drivetrains and are often asked to do daily commuting duty in heat, traffic and short-trip use. AMSOIL scooter oil is designed around those realities rather than treating scooters like small cars.

Scooter product

• Formula 4-Stroke® 100% Synthetic Scooter Oil — built specifically for modern air-cooled and water-cooled four-stroke scooters. It is intended for scooter engines, transmissions and gearboxes and is a strong choice for riders who want cleaner operation, wear control and reduced friction in daily use.

Scooter service notes

Some scooters also have separate transmission or final-drive service needs. Use the lookup guide to confirm oil, filter and supporting fluid requirements for your exact scooter.

Dirt bikes and off-road motorcycles

AMSOIL supports modern dirt bike applications, including motocross, trail, cross-country and hard-enduro machines.

Popular fit examples

Honda CRF450R
Yamaha YZ450F
KTM 450 SX-F
Husqvarna FC 450
KTM 300 XC-W
Yamaha YZ125

Why off-road bikes need different products

Dirt bikes punish oil with heat, repeated clutch work, rapid gear changes, dirt exposure and high-rpm riding. Off-road riders need fluids that hold up under shear, keep clutch feel predictable and protect gears and bearings when the bike is ridden hard.

Four-stroke dirt bike oils

• 10W-40 100% Synthetic Dirt Bike Oil — a strong choice for many Japanese four-stroke dirt bikes and riders who want steady clutch feel and dependable gear protection.
• 10W-50 100% Synthetic Dirt Bike Oil — a common fit for many KTM and Husqvarna off-road applications and a smart pick when the bike calls for more hot-temperature protection.
• 10W-60 100% Synthetic Dirt Bike Oil — for specific high-performance dirt bike applications that call for this heavier race-oriented viscosity.

Separate-sump transmission protection

• 100% Synthetic Dirt Bike Transmission Fluid — built for two-stroke and four-stroke dirt bikes that use a separate transmission sump. It uses strong film protection, clutch-friendly friction characteristics and anti-wear chemistry to help the clutch and gearbox hold up under repeated abuse.

Two-stroke dirt bike support

Many two-stroke off-road applications are also supported in the AMSOIL Motorcycle Lookup Guide.

• DOMINATOR® 100% Synthetic 2-Stroke Racing Oil — a strong option for high-heat, high-rpm riding where riders want clean burning and strong film protection.
• Use the lookup guide to confirm the correct two-stroke oil and transmission-fluid combination for your exact premix or injection application.

Off-road air-filter service

• AMSOIL Air Filter Oil — a smart add-on for off-road bikes with foam filters. It is designed to help stop dirt and water contamination while maintaining airflow.

Motorcycle maintenance essentials

Oil filters

• AMSOIL Motorcycle Oil Filters — advanced full-synthetic media helps trap small wear-causing contaminants and supports long equipment life. The lookup guide will match the correct filter size for V-twin, metric, dirt bike and many scooter applications.

Brake fluid

• DOT 3 and DOT 4 100% Synthetic Brake Fluid — a strong upgrade for riders who want dependable brake feel, moisture resistance and modern ABS compatibility. It also exceeds DOT 3, DOT 4 and DOT 5.1 specifications.

Coolant

• Powersports Antifreeze & Coolant — pre-mixed 50/50 with high-purity water and made for liquid-cooled powersports equipment. It helps control operating temperature and is a clean, ready-to-use option for many motorcycles, scooters and dirt bikes.

Chain-drive maintenance

• AMSOIL Chain Lube — a strong add-on for chain-drive street bikes and dirt bikes. It helps protect chains and sprockets, supports longer chain life and leaves a coating designed to stay put instead of making a mess.

Fuel-system care

• Quickshot® Gasoline Treatment and Stabilizer — a strong choice for riders dealing with ethanol-related drivability issues, dirty injectors or carburetors, and hard starts after sitting.
• Motorcycle Octane Boost — a useful option for bikes that benefit from additional octane support, cleaner combustion chambers and reduced knock or ping.
• Gasoline Stabilizer — ideal for seasonal storage. It helps keep fuel fresh, limits corrosive deposits and is a strong fit for motorcycles that sit between riding seasons.

Storage protection

• Engine Fogging Oil — a smart product for off-season storage or bikes that will sit for extended periods. It helps protect internal engine parts against corrosion and dry starts.

Intake-system cleanup

• Power Foam® Carburetor and Induction-System Cleaner — useful for bikes and scooters that have picked up varnish or gum from ethanol fuel or storage. It is especially helpful for powersports engines that run, then sit.

Cleaning and appearance products

Fast wash and shine

• Miracle Wash® Waterless Wash and Wax Spray — a practical choice for street bikes, touring bikes and scooters when you want quick cleanup and a glossy finish without a full wash setup.

Degreasing and garage cleanup

• Heavy-Duty Degreaser — useful for chain fling, greasy wheel buildup, engine-case grime and general service-bay cleanup.

Dirt-bike cleanup and protection

• Mudslinger® Mud and Dirt Repellent — especially useful for dirt bikes. It helps mud and grime release more easily after the ride and reduces cleanup time.
• Heavy-Duty Metal Protector — a strong follow-up after washing or wet riding. It helps protect exposed metal surfaces against moisture, salt and corrosion.
