Motul Twin Gear 75W-90 100% Synthetic Ester Motorcycle Transmission Oil 1L Pack of 5

Motul Twin Gear 75W-90 is a 100% synthetic ester-based high-performance motorcycle transmission oil engineered for gearboxes operating under extreme heat, heavy torque, and severe shock loads.

It is specifically suited for compatible Big Twin 4-speed, 5-speed, and 6-speed transmissions, including Harley-Davidson motorcycles and similar V-Twin applications requiring a 75W-90 API GL-5 gear lubricant.

The advanced Ester Technology formulation provides exceptional oil-film strength, high-temperature protection, reduced friction, smoother shifting, and extended protection for heavily loaded transmission components.

This package includes five 1-liter bottles, providing a total of 5 liters.

WHY THIS GEAR OIL:

100% synthetic Ester Technology provides excellent resistance to extreme temperatures and heavy mechanical loads.

High-performance extreme-pressure protection helps protect gear teeth and other heavily loaded components against wear.

Molecular polar bonding technology helps the lubricant adhere to metal surfaces, creating a durable protective film.

A low traction coefficient helps reduce internal friction, wear, and power loss within the transmission.

The formulation helps promote smoother and quieter shifting, while maintaining strong oil-film protection at elevated temperatures.

Excellent low-temperature fluidity supports easier shifting when the gearbox is cold.

Provides anti-corrosion and anti-foam protection for demanding motorcycle transmission applications.

Compatible with seals and yellow metals commonly used in gearbox construction.

FITMENT AND COMPATIBILITY NOTE:

Motul Twin Gear 75W-90 is designed for compatible Big Twin, Harley-Davidson, and similar V-Twin motorcycle transmissions requiring an SAE 75W-90 gear lubricant meeting API GL-5 or SAE J2360.

It is suitable for compatible 4-speed, 5-speed, and 6-speed transmissions using helical or straight-cut gears.

Do not assume compatibility with every Harley-Davidson or motorcycle transmission. Always verify the required viscosity, API specification, transmission design, and fluid capacity before use.

This product is a dedicated transmission gear oil and should not automatically be substituted for engine oil, primary-chaincase lubricant, or another drivetrain fluid unless specifically permitted by the motorcycle manufacturer.

IMPORTANT NOTES:

Drain intervals should follow the motorcycle manufacturer's recommendations and individual operating conditions.

Severe use, high temperatures, heavy loads, or aggressive riding may require shorter service intervals.

A complete drain and refill is preferred when changing lubricants.

Always verify the current motorcycle service manual before installation.
