The original Syn

Others may have put “Syn” 
on the label but we were the first—
the original synthetic.

Backed by decades of racing that have fine-tuned our formula, Motul’s TWIN line handles the heat, the load, and the kind of riding that stock oil just can’t keep up with. No breakdown. No drag. No compromise. So you can ride like hell.

Performance isn’t one-size-fits-all

Motul gives your engine, primary, and gearbox their own purpose-built protection—something a single shared oil can’t match.

Built for real heat, real performance

Your engine is where the real work happens—and where stock oil starts to give up. Motul’s TWIN Synthetic Motor Oil is engineered to handle the heat, torque, and stress of V-Twin riding.

Strength for 
every shift

Your gearbox doesn’t need the same oil as your engine—it needs something stronger. Motul’s TWIN Gear Oil is designed to protect high-load gears, reduce friction, and keep shifts smooth under serious pressure. Purpose-built for durability where it matters most.

The right formula for your Primary

The primary has its own job—and its own demands. Motul’s TWIN Primary Chaincase & Gear Oil stabilizes clutch engagement, reduces wear, and delivers consistent performance ride after ride. Because your clutch isn’t your crank, and it deserves oil made for its system.

Your build is custom. 
Your oil should be too.

Every custom build is a collection of intentional choices—power, handling, sound, style. Your oil should match that level of intent. Motul’s V-Twin line gives each chamber the formula it actually needs, so your upgrades run at their peak and stay protected mile after mile.
