Motul 300V Factory Line 10W40 Racing Engine Oil — 4L ESTER Core® for Maximum Power & Wet‑Clutch Shift

Motul 300V Factory Line Road Racing 10W40 is a 100% synthetic 4-stroke motorcycle racing engine oil formulated with ESTER Core® Technology to maximize power, protect high-revving components, and improve shifting in wet-clutch gearboxes.

Built from ester-based synthetic base stocks and a targeted additive package, this Factory Line formulation is derived from Motul's motorsport experience to serve both track-day demands and aggressive street riding. It is engineered to reduce internal friction, maintain oil film strength at extreme temperatures, and meet the compatibility needs of modern sportbike engines, integrated gearboxes, and wet clutches. The product exceeds JASO T904 standards and is supplied in a 4L container (also available in 1L formats) with a SAE viscosity of 10W-40.

How does Motul 300V improve engine power and throttle response?

ESTER Core® Technology creates polar molecular interactions with metal surfaces, reducing friction losses inside the engine. Less friction means more of the engine’s output reaches the drivetrain, yielding measurable gains in acceleration and throttle feel without mechanical modifications.

• Advanced esters reduce boundary friction at piston rings and bearings
• Shear-stable synthetic base maintains viscosity under high RPM
• Additives tuned to preserve power delivery across temperature ranges

Will this oil help with shifting and clutch performance?

Yes — Motul 300V is formulated for motorcycles with integrated gearboxes and wet clutches, delivering smoother, more precise shifts. The lubricant minimizes clutch drag and reduces the chance of clutch slip under heavy loads by maintaining consistent friction characteristics.

• Designed for wet-clutch compatibility and quick, clean shifts
• Reduces gear engagement shock for longer transmission life
• Optimized additive package for clutch feel and durability

How does this oil protect the engine under extreme track conditions?

Racing environments push engines to high RPMs and temperatures; Motul 300V sustains a strong lubricating film and resists mechanical breakdown. Exceptional shear stability and thermal resistance help prevent metal-to-metal contact and extend component life during prolonged hard use.

• High film strength to guard against wear at elevated loads
• Excellent thermal and oxidative stability for longer oil life
• Formulation tested in motorsport settings for repeatable performance

What engine types and applications are appropriate for this oil?

This 10W-40 100% synthetic oil is tailored for modern high-performance 4-stroke motorcycle engines, including sportbikes with integrated gearboxes, wet or dry clutches, and catalytic converters. It is suitable for track days, racing teams, and riders seeking race-derived lubrication for spirited street riding.

• Compatible with high-revving sportbike engines and integrated gearboxes
• Meets or exceeds JASO T904 requirements for motorcycle service
• Useful for both competition and performance-focused street use

Who is this for: Motul 300V Factory Line Road Racing 10W40 is intended for racers, track-day enthusiasts, and performance riders who demand top-tier lubrication that prioritizes power extraction, reliable protection at high temperatures, and predictable clutch and gearbox behavior. Choose this oil if you ride modern sport motorcycles and want a motorsport-proven ester-based lubricant that supports sustained high-RPM operation and responsive throttle control.
