Synthetic V-Twin Primary Fluid

AMSOIL V-Twin Synthetic Primary Fluid is purpose-built for bikers who prefer a dedicated primary chaincase lubricant. Its balanced formulation delivers consistent clutch feel for confident takeoffs, helping riders avoid killing the engine. It also protects components against wear to help riders get the most out of their bikes. V-Twin Synthetic Primary Fluid is Warranty Secure™ and will not void your motorcycle's warranty. It is a cost-effective, high-performance alternative to original equipment manufacturer (OEM) fluids.
Delivers Consistent Clutch Feel & Smooth Acceleration

V-Twin Synthetic Primary Fluid is formulated with a balanced additive system that provides consistent clutch performance and feel. It helps riders easily find neutral and promotes smooth acceleration, whether in stop-and-go city conditions or when on the highway. Its superior load-holding capacity helps prevent clutch slip for confident takeoffs.
Protects Against 
Chain, Gear 
& Bearing Wear

V-Twin Synthetic Primary Fluid contains a heavy dose of anti-wear additives to protect the gears, chain and compensator bearing from premature wear. Its superior film strength helps protect against shock-loading, promoting reduced wear and longer component life.
Helps Reduce 
Operating Temperatures

In extreme heat, V-Twin Synthetic Primary Fluid's thermally stable synthetic formulation naturally resists the harmful effects of thermal breakdown. It helps components stay cool and achieve optimum performance and life.
Maximizes Energy Efficiency

V-Twin Synthetic Primary Fluid's balanced formulation reduces energy lost to drag in cold-temperature riding conditions. It promotes smooth shifts at startup and maximizes energy efficiency.

Use the oil designed for your bike
When you need the best for your bike, you use a dedicated lubricant. I've stress tested this oil up to 7K miles with a great oil analysis report
I noticed when I switched from Amzoil 20/50 motorcycle engine oil to the Synthetic V-Twin Primary Fluid in the chaincase of my 2013 Harley Davidson Streetglide it sounded quieter riding slow in first gear, in places like my street or in parking lots. That first gear whine just went away. With that kind of friction gone I feel like it absolutely must be giving my machine better protection.
Using this oil for years and years to come
I have been using this oil for over 17 years and my bike has had no issues due to consistency in oil changes
I would buy this product again & again
I use these products both mine and my wife's 2015 Harley Davidson Road Glides. I've used them for many years with great success. Love Amsoil products.
Yes I will buy this stuff again
This stuff works great on a stock Harley clutch however if you are running a Barnett Clutch you can't run synthetic oil in the primary.
