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.
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.
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.
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.
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.

I will continue to buy Amsoil Fluids for my motorcycle
I was having problems getting my motorcycle into neutral until I started using Amsoil Primary Fluid. The motorcycle has responded well to my using separate fluids instead of using one fluid for all three purposes.
