Additionally, touring and adventure bikes are built for long, cross-country trips that benefit from extended drain intervals. And the increased heat generated by compact, high-performance engines can rapidly accelerate oil breakdown, leading to deposit formation that robs motorcycle engines of efficiency and power.

Protection and Performance

The advanced technology in AMSOIL Synthetic Metric Motorcycle Oil is specifically engineered to prevent oil breakdown under extreme heat and pressure to deliver maximum performance. It promotes smooth, consistent shifting and protects motorcycle engines and transmissions against wear, helping them run cleaner and cooler and shift smoother.

By maximizing your engine’s performance and responsiveness, you’ll enjoy thrilling delivery of power and torque for maximum acceleration and cornering ability. And with drain intervals up to twice the bike manufacturer’s recommendations, you can also confidently wander far from home.

Proven on the Road and Dyno

We installed AMSOIL 5W-40 Synthetic Metric Motorcycle Oil in a BMW R 1250 GS* and rode it aggressively on pavement and dirt. Then we strapped it to our dyno and pushed the engine to its limit. After 12,000 miles, twice the recommended drain interval, we tore the bike down and inspected the engine and transmission components for wear.
