Motul 300V Factory Line Off-Road 5W-40 4T Full Synthetic Racing Motorcycle Oil | ESTER Core Engine Lubricant, JASO MA2 Wet Clutch Compatible, 4-Stroke Dirt Bike ATV UTV Gearbox Protection 4L

Motul 300V Factory Line Off Road 5W-40 is a 100% synthetic racing motor oil built on ESTER Core technology, developed in direct partnership with factory off-road racing teams competing in the Dakar Rally, FIM International Six Days of Enduro, and World Motocross Championship. This formulation prioritizes maximum power output, engine and gearbox protection, and wet clutch performance over extended drain intervals -- it is a pure competition lubricant designed for riders who demand professional-grade performance from their machinery. The ESTER Core formulation reduces internal friction to deliver measurable torque gains of up to 2.5%, while maintaining a 220C flash point and 4.2 mPa.s HTHS viscosity at 150C for reliable oil film strength under extreme thermal and mechanical loads. JASO T903:2023 Level MA2 certified for wet clutch systems, ensuring positive clutch engagement with no slippage. Recommended for 4-stroke off-road motorcycles from KTM, Sherco, Aprilia, MV Agusta, Honda, Yamaha, Husqvarna, and Gas Gas, as well as ATV and UTV applications requiring 5W-40 viscosity. SAE 5W-40 with a pour point of -48C (-54F) for cold-weather starting. Change after each race event or every 500-2000 km. For street and touring applications requiring longer service intervals, consider Motul 7100 4T.

• Maximum Power Output with ESTER Core Technology: Engineered with Motul's proprietary ESTER Core technology, a 100% synthetic formulation of ester-based compounds that reduces internal friction to deliver measurable torque gains. This racing-grade motor oil maintains stable oil film adhesion at extreme temperatures, providing consistent power delivery through demanding off-road conditions including sand, mud, and rocky terrain where sustained high-RPM operation is required.
• Engine and Gearbox Protection Under Extreme Conditions: Provides exceptional oil film resistance with a 220C (428F) flash point and 4.2 mPa.s HTHS viscosity at 150C, delivering reliable protection under sustained high-RPM operation and extreme heat. The full synthetic formulation guards engine internals and integrated gearboxes simultaneously, maintaining stable oil pressure throughout races, enduro events, and aggressive trail riding in harsh off-road environments where water, mud, and dust contamination constantly challenge lubricant integrity
• Precise Wet Clutch Engagement and Grip Control: Formulated to meet JASO T903:2023 Level MA2 certification, the highest friction standard for wet clutch performance, ensuring precise clutch engagement and grip control in conditions demanding maximum traction. Riders experience consistent clutch feel with no slippage during hard launches, technical single-track sections, and aggressive throttle application. The additive package prioritizes extreme pressure protection over the detergents found in street oils, delivering positive clutch lockup that competitive riders depend on
• Broad Off-Road and Powersport Application Compatibility: Recommended for 4-stroke motorcycle engines with integrated gearbox and wet clutch systems including KTM, Sherco, Aprilia, MV Agusta, Honda, Yamaha, Husqvarna, and Gas Gas dirt bikes. Validated at the Dakar Rally and FIM International Six Days of Enduro (ISDE) with factory racing teams, this formulation is also suitable for ATV and UTV powersport applications requiring 5W-40 viscosity, exceeding existing motorsport lubrication standards for engines operating under extreme mechanical and thermal stress
• Low Oil Consumption and Consistent Viscosity Stability: Exclusive formulation of low-volatility synthetic base oils and esters minimizes oil consumption even under sustained high-stress racing conditions, with kinematic viscosity of 13.0 mm2/s at 100C and 72.0 mm2/s at 40C maintaining consistent protection across the full operating temperature range. A TBN (Total Base Number) of 8.7 mg KOH/g provides strong acid neutralization throughout the service interval. Designed as a race-focused formulation for frequent changes after race events or every 500-2000 km, packaged in recyclable bottles manufactured with 50% recycled plastic
