Reduces Friction, Heat and Wear
In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.
Smooth, Confident Shifts
AMSOIL 10W-40 Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. It also increases blow-by. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit. Some have switched from 20W-50 to 10W-40 to reduce foaming but with AMSOIL you can stick with your proper viscosity.

Delivers Superior Rust and Corrosion protection
No one else seems to offer this aspect..
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.
AMSOIL 10W-40 Synthetic Metric Motorcycle Oil is engineered for motorcycles that require 10W-40 motorcycle oil, including those made by Honda, Yamaha, Kawasaki, Suzuki, Triumph, Can-Am and BMW and other bikes where 10W-40 is required. Recommended for transmissions requiring an API GL-1 fluid. Not recommended where an API GL-4 or GL-5 gear oil is required.
I’ll tell you what – This 10W-40 is recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions. We always get “Well I never go that long”. I just had a guy who went two years and 10,000 miles and oil analysis said the oil was still good.. While that’s not going to be covered by AMSOIL’s warranty I sure gives you confidence. That’s what you should expect when a company is constantly engineering for a better more advanced product. When using an oil filter other than AMSOIL Ea Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations (we shouldn’t have to tell you that but that’s the time we live in); oil changes are at the owner’s discretion.
AMSOIL Synthetic Metric Motorcycle Oil is Warranty Secure, keeping your factory warranty intact. It is a high-performance replacement for vehicle manufacturer-branded products and is also backed by the AMSOIL Limited Warranty (G1363). For details, visit www.amsoil.com/warrantysecure.

Excellent engine life

I’ve been using Amsoil 10W-40 motorcycle oil in my street bikes for over 15 years. I had a CBR600 with 95000km that used Amsoil from the first oil change. That bike had a spirited life with lots of commuting and many high paced track days. At that high odometer it had great dyno numbers, didn’t burn any oil, and had never had any engine problems. When I was replacing my clutch at about 85000km I inspected some engine internals and it was amazing how clean a free of wear everything was.

Great for my road bike. Great for my race bike.

I personally run AMSOIL 10W-40 Synthetic Metric Motorcycle Oil through my road bike for the street and race bike at the track. This oil has always held up very well for me and always seems to outlast the filter. I swap it out every time I make a filter change (just out of habit), but it always looks as clear as when I first put it in.
When racing, I’m always on the throttle and make very hard downshifts (probably worse than I should). I have yet to see this oil deteriorate on me, even when stressing a motor very hard. I couldn’t be happier with its performance so far this race season.
I recommend AMSOIL products to everyone I come across, whether on the street or at the track. As long as they continue to make high quality products, I will continue to do so moving forward.
