Bikers of all stripes are gearing up for another season of motorcycle rallies and summer road trips. Whether you’re into V-twins or metric bikes, AMSOIL synthetic motorcycle oils are dialed-in to meet the unique demands of your bike.

V-Twin Motorcycles

Powerful, hot-running V-twins generate intense heat, especially in slow-moving rally or parade traffic. Air-cooled bikes rely on a steady flow of air over the cooling fins to conduct heat away. Stop-and-go driving and periods of idling on hot summer days can quickly cause the engine temperature to skyrocket. If a motorcycle oil cannot withstand hot operating temperatures, its ability to provide adequate engine protection is compromised.

In addition, the intense heat and mechanical action inside a motorcycle engine can cause motorcycle oils to lose viscosity, or shear. Bikes that share a sump between the engine and transmission are especially prone to viscosity loss due to shear. AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable and does not thin from mechanical activity. It does an excellent job protecting your expensive bike against wear.

AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil has been updated with labels and packaging that bring it in line with the rest of the V-Twin line introduced last year. SAE 60 Synthetic V-Twin Motorcycle Oil labels and packaging will follow in May. Together they complete the AMSOIL V-twin product line in time for the start of motorcycle season. New labels will be available when current inventory is depleted.

AMSOIL Synthetic V-Twin Motorcycle Oil delivers excellent performance in transmissions and primary chaincases, offering the convenience of one lubricant for all three areas of your bike. Some bikers, however, prefer lubricants formulated specifically for their transmission or chaincase. AMSOIL Synthetic V-Twin Transmission Fluid and Synthetic V-Twin Primary Fluid offer excellent performance in these situations.

Metric Motorcycles

The metric motorcycle market is divided into three segments.

  • Metric Sport Bikes
  • Metric Cruisers
  • Metric Touring


Sport bikes (crotch rockets) need wet-clutch-compatible lubricants that deliver consistent shift performance. The high speeds and rpm at which riders travel can cause oil to foam, requiring lubricants that offer superior foam control.

AMSOIL Synthetic Metric Motorcycle Oil helps you push your bike to the edge. Its advanced synthetic technology maximizes engine responsiveness while delivering excellent wet-clutch compatibility for smooth shifts. By controlling foam, it helps you confidently push your engine toward the red line for maximum speed, acceleration and cornering ability.


Like sport bikes, metric cruisers are defined by engine responsiveness, power and speed. Superior handling, easy shifting and reliability are also important traits.

AMSOIL Synthetic Metric Motorcycle Oil delivers smooth, confident shifts and excellent wear protection. By resisting extreme heat and helping cool hot engines, it promotes peace of mind and confidence.


Metric touring bikes typically accentuate comfort, luxury and the adventure associated with long, cross-country trips. AMSOIL Synthetic Metric Motorcycle Oil enhances reliability by delivering superior engine protection. Its outstanding performance provides the security of knowing your bike is going to provide trouble-free operation mile after mile. It extends drain intervals up to twice the bike manufacturer’s recommendations, allowing you to enjoy peace of mind when far away from home and unable to stop for an oil change. AMSOIL Synthetic Metric Motorcycle Oil’s wet-clutch compatibility enables smooth shifts for a comfortable ride.
