What Makes Ester Technology a Game-Changer?
Motul is a pioneer in using Ester technology for consumer motorcycles, a feature derived directly from their elite racing heritage. But what does it mean for your daily or long-distance touring ride?
-
Anti-Wear Shield: Esters are polar molecules, meaning they naturally cling to metal engine components. Even after your bike has been sitting parked for days, a microscopic layer of oil remains on the gears and pistons. This virtually eliminates wear during dry cold starts.
-
Smoother Gear Shifts: One of the most immediate things riders notice after switching to Motul 7100 is how buttery smooth the transmission becomes. Clunky gear changes disappear, and finding neutral becomes effortless—a massive blessing when riding through heavy stop-and-go traffic.
-
Extreme Thermal Stability: Long-distance touring often means pushing your engine for hours at high RPMs. Motul 7100 maintains its viscosity under extreme heat, preventing oil breakdown and ensuring your clutch doesn't slip when the engine gets hot.

Optimized for Wet Clutches (JASO MA2 Standard)
Most modern motorcycles share the same oil between the engine and the wet clutch system. Using car oil or sub-par motorcycle oil can cause catastrophic clutch slippage.
-
JASO MA2 Certified: Motul 7100 meets the strict JASO MA2 specifications, ensuring perfect friction compatibility with your wet clutch. This means optimal power transfer to the rear wheel when you twist the throttle, even under heavy touring loads.
-
Catalytic Converter Friendly: With low phosphorus and sulfur formulations, this oil ensures your bike’s exhaust and emissions systems stay clean and functional over tens of thousands of miles.

"I've been using Motul 7100 in my touring bike for years. Before my last 2,000-mile trip, I did a fresh oil change with this. The difference in shifting is night and day—no more clunkiness. Even when riding through 95°F weather loaded with luggage, the engine ran noticeably cooler and smoother. I won't put anything else in my bike."
