Racing or riding a modern 4-stroke dirt bike hard generates massive internal heat and intense mechanical shear forces that will quickly break down conventional motor oils. Maxima Extra is a 100% full-synthetic, triple-ester engine oil specifically engineered for riders who demand maximum horsepower and uncompromising hardware protection under the most severe off-road conditions.
The secret to Extra's unyielding performance is its proprietary triple-ester base combined with a shear-stable polymer system. Esters naturally cling to internal engine components, maintaining a slick protective boundary layer even during cold starts. Meanwhile, the advanced additive package fights the brutal mechanical forces of the transmission to eliminate "shear-down," ensuring your clutch engagement remains crisp and your engine stays protected from the drop of the gate to the end of a grueling desert race.
Triple-Ester Synthetic Base: Formulated with a synergistic blend of exotic esters that act like magnets, naturally adhering to metal surfaces to provide critical anti-wear protection the exact moment you hit the starter button.
Eliminates Shear-Down: Modern shared-sump dirt bikes brutalize oil through the transmission gears. Extra's regenerative polymers resist mechanical shearing, maintaining its specified viscosity and film thickness far longer than conventional motor oils.
Optimized Clutch Performance: Formulated to meet stringent JASO MA standards for wet clutches. It prevents plate slippage and delivers consistent, predictable engagement even when you are aggressively fanning the lever in technical terrain.
Maximum Power Output: The surface-active chemistry drastically reduces internal friction and operating temperatures, allowing your engine internals to spin freely and deliver maximum horsepower to the rear wheel.
Unmatched Cleanliness: Exceeds the modern API SN PLUS requirements. The world-class additive package actively prevents sludge, oxidation, and carbon buildup to keep your piston rings moving freely.
Break-In Period Warning: Because Maxima EXTRA provides such an incredibly slick, frictionless boundary layer, you should never use it to break in a brand-new engine or a freshly rebuilt top end. Your new piston rings require a small amount of controlled friction to properly file themselves down and seat against the cylinder wall. Always run a dedicated mineral break-in oil for your first few heat cycles, drop that oil, and then switch over to Maxima Extra for the rest of the engine's life.
