The best lubrication on two wheels

Metric Motorcycles

Street bikes depend on oil for reliability

Street bike riders can be a different bread. They can be high revving on a Ducati or laid-back cruising on a Honda Goldwing, but the open-air experience is one that can’t be beat. Summers are short enough, and no rider has the time for inconvenient repairs or maintenance, much less a roadside breakdown or the expense that goes with motorcycle engine repairs. Without proper lubrication, it is possible that the riding season can be cut short.

Rather than literally cook the engine under extreme heat or miss shifts due to viscosity breakdown – conditions that many OEM oils experience – riders can get the dependability of class-leading lubrication and heat reduction with AMSOIL Synthetic METRIC Motorcycle Oil. It runs cooler. It resists thermal breakdown. It protects better against shear forces. And it keeps riders on the saddle for more days of the short season.

Find the perfect match motorcycle oil and AMSOIL Ea® oil filter for your next oil change.

Only the best street bike oil viscosity and oil filter for your ride

Locating the right oil and EaOM oil filter for a particular motorcycle is easy on the AMSOIL site with an intelligent Look-up Guide that filters by year, make, and model.

The AMSOIL street bike oil and filter lookup will find the right oil viscosity, oil capacity and long life oil filter for your motorcycle engine and keep your bike running like new. Vintage bike owners prefer the AMSOIL brand to protect their hard to find engines and transmissions. Keep your bike running like new for years.

How AMSOIL synthetic street bike oil outperforms

The reviews tell the full story. From BMW adventure and urban mobility bikes to Spyder Can-Am models and Yamaha motorcycles of all kinds, AMSOIL buyers never go back to lesser OEM oils and bargain products that simply don’t deliver the same level of protection.

AMSOIL Synthetic METRIC Motorcycle Oil is proven to help reduce operating temperatures in air-cooled street bike engines and provides unrivaled rust and corrosion protection while maintaining a clean, deposit-free crankcase. It’s perfect for high-RPM engines as its anti-foam additives prevent metal-on-metal wear better than other leading brands.

The difference is noticeable. Riders say they experience better clutch engagement and smoother shifts with AMSOIL METRIC Motorcycle Oil. Its formula specifically omits friction modifiers that could cause slippage and glazing so every shift is crisp and clean.

AMSOIL Synthetic METRIC oil is API SM, JASO MA/MA2 certified and is recommended for Can-Am, Kawasaki, Honda, BMW, Triumph, and Yamaha motorcycles among others that require 10W-40 oil. Better yet, using AMSOIL can double the OEM’s recommended drain interval!
