The original Syn.

We didn’t just put “Syn” on the label—we pioneered it and refined it through decades of racing. That’s why our 20W-50 TWIN Motor Oil is engineered for the demands of a modern V-Twin engine. Its advanced ester-based formula delivers stable viscosity, stronger film retention, and superior thermal resistance. And 
for riders who prefer a simplified maintenance routine, its robust formulation 
is versatile enough to perform in the engine, primary, or gearbox—without sacrificing protection.

Reliable protection in high-heat, high-load engines

Engineered to handle the elevated temperatures and stresses found in large-displacement, air- and water-cooled twin engines.

Reduced wear from start-up to sustained riding

Advanced Ester technology with molecular polar bonding helps oil cling to metal surfaces, providing a protective film that reduces wear, especially at start-up.

Strong defense for high-torque engine components

A high level of ZDDP extreme-pressure additives supports durability and extended engine life under demanding operating conditions.

Smooth, consistent wet-clutch performance

JASO MA2 certification ensures proper clutch grip, helping prevent slippage, chatter, and premature wear.
