Shop by ride type

Choose your ride type

Pick your ride type, then confirm fitment in the lookup guide before ordering model-specific items.

V-Twin motorcycles

V-Twin oil and service products

Start here for V-Twin oil, primary fluid, transmission fluid and complete oil-change kit guidance.

For V-Twin bikes, use the lookup guide before choosing a kit or combining engine, primary and transmission products.

Street and adventure motorcycles

Street, sport, touring and adventure oils

Use this section if you ride a four-stroke metric motorcycle and want to compare common motorcycle-oil viscosities.

If the bike has shared engine, gearbox or clutch requirements, confirm the AMSOIL recommendation before ordering.

Dirt and off-road motorcycles

Dirt bike and off-road products

Use this section for four-stroke dirt bike oils, separate-sump transmission fluid and two-stroke motorcycle oil support.

Two-stroke choices depend on the bike, oiling system and manufacturer recommendation, so use the lookup guide before ordering.

Scooters

Scooter oil

Scooter riders can start here, then use the lookup guide to confirm the correct oil for the exact model.

Filters and fluids

Complete the service

Once the main oil path is clear, use this section for filters, brake fluid, coolant, suspension fluid, gear lube and grease service items.

Do not guess filter numbers, capacities, final-drive requirements, brake-fluid requirements or coolant compatibility. Use the lookup guide and the owner manual.

Fuel, storage and chain care

Keep the bike ready between oil changes

These products help round out a motorcycle maintenance routine after the oil, filter and service-fluid choices are clear.

Cleaning and garage support

Clean, protect and organize the rest of the job

These add-ons are useful for cleanup, detailing, storage and service work after the motorcycle-specific products are handled.

Account paths

Repeat rider and shop account options

Use these self-serve AMSOIL account paths after you know which motorcycle products you want to order or compare.
