Purpose and Specifications

LIQUI MOLY Motorbike Gear Oil 75W-90 is a fully synthetic, high-performance transmission fluid designed specifically for motorcycle gearboxes and manual transmissions. This oil reduces friction between moving parts, absorbs and dissipates heat during operation, and maintains protective seals to prevent dirt and water from entering the transmission.

The 75W-90 viscosity rating means the oil flows easily in cold conditions (winter starts) while maintaining a protective film at high operating temperatures. This wide temperature range ensures reliable protection whether you're riding in freezing weather or pushing your bike hard on warm days.

• Excellent wear protection – Keeps gear teeth and synchronizers in top condition
• Smooth, precise shifting – Even under extreme riding conditions
• Reduces transmission noise – Quieter gearbox operation
• Superior corrosion protection – Protects internal components from rust and degradation
• Extended oil life – Resists breakdown and aging, reducing change frequency

Specifications: API GL5 performance class, complies with MIL-L 2105 C/2105 D military standards. Suitable for all motorcycle types including BMW R-series models from 2004 onward.

When to Use / Replace?

Check your motorcycle's owner manual for the exact replacement interval, as this varies by model and riding conditions. Most motorcycles require transmission oil changes every 6,000 to 12,000 kilometers or once per year, whichever comes first. If you ride in extreme conditions (racing, heavy towing, or very hot climates), change the oil more frequently – every 4,000 to 6,000 kilometers.

Use this oil when: your transmission feels sluggish or grinding, you notice increased noise from the gearbox, or during routine maintenance as specified in your service schedule. Always use the full 500 ml bottle undiluted for optimal effectiveness.

Operating temperature range: This oil performs reliably from approximately -20°C to +100°C, making it suitable for year-round riding in most climates.

Frequently Asked Questions

Q: Can I use this oil in my car transmission?
A: No. This product is formulated specifically for motorcycle gearboxes. Car transmissions require different oil types (manual transmission fluid or automatic transmission fluid). Always follow your vehicle manufacturer's recommendations.

Q: How long does an unopened bottle last?
A: Properly stored in a cool, dry place, unopened LIQUI MOLY gear oil maintains quality for several years. Once opened, use the entire contents within one season or service interval to ensure the oil hasn't absorbed moisture or degraded.

Q: Will this oil reduce my fuel consumption?
A: Yes, slightly. The optimized viscosity reduces internal friction in the transmission, which can improve fuel efficiency by a small margin – typically 1-3% depending on riding style and conditions.
