Purpose and Specifications

Liqui Moly 1617 Motorbike Gear Oil (GL4) 80W is a high-performance mineral-based transmission oil designed for highly stressed motorcycle transmissions and final drives. This 500ml bottle ensures smooth and precise gear shifting even under extreme loads, thanks to its selected base oils and additives that provide high wear resistance and excellent pressure absorption.

It reduces running noise, protects seals from damage, and maintains reliable performance across a wide temperature range from -30°C to +130°C. Approved to API GL4, MIL-L 2105, ZF TE-ML 02B, and ZF TE-ML 17A standards, it delivers longer transmission life and quieter operation without aggressive additives that could harm yellow metals like brass synchronizers.

When to Use / Replace?

Use this oil in motorcycles with manual transmissions requiring GL4 spec oils, especially for high-performance riding or track use. Replace every 10,000-20,000 km or 12 months, whichever comes first, or sooner if you notice hard shifting, noise, or grinding gears. Its excellent aging resistance gives it a shelf life of 5 years when stored properly in a cool, dry place.

Ideal for daily commuters and sport bikes operating in varied conditions, keeping shifts crisp from cold starts to hot track days.
