Liqui Moly Motorbike 4T Synth 5W-40 Street Race Full Synthetic Motor Oil — 4 L, High Shear Stability & Wet-Clutch Friendly

Liqui Moly Motorbike 4T Synth 5W-40 Street Race is a full-synthetic, race-developed 4T engine oil that delivers high-performance protection, low wear, and smooth clutch and gearbox action for modern motorcycles.

Created from the insights gained on racetracks, this 4-liter formulation balances extreme stress protection with everyday rideability. It uses advanced synthetic base stocks and tailored additives to reduce friction, maintain engine cleanliness, and resist shear and thermal breakdown under high loads. The result is consistent viscosity, reliable lubrication, and compatibility with catalytic converters for street-legal motorcycles.

How does this oil protect my engine under racing or heavy-load conditions?

The Street Race 5W-40 blend is engineered for high shear stability and excellent ageing resistance, helping the oil keep its protective film even when temperatures spike and rpm climb. That sustained film reduces metal-to-metal contact and lowers wear rates across engine components.

• High shear stability for consistent viscosity under stress
• Advanced additives that minimize wear at elevated temperatures
• Formulation tested on racing machines for real-world durability

Will it keep my engine clean and help catalytic converters?

This fully synthetic oil includes detergents and dispersants designed to limit deposits and sludge formation, promoting cleaner combustion chambers and oil passages. It is tested and approved for use with catalytic converters, reducing the risk of compatibility issues while supporting emissions equipment longevity.

• Detergent package that minimizes carbon and varnish buildup
• Optimized formulation compatible with catalytic systems
• Promotes steady combustion and cleaner exhaust performance

How does it affect clutch feel and gear shifting on my motorcycle?

The lubricant's friction properties are tuned for motorcycles with wet clutches, delivering smooth clutch engagement and predictable gear shifts. Riders will notice reduced clutch chatter and more consistent shifting, which enhances control whether commuting or riding spiritedly.

• Balanced friction characteristics for smooth wet-clutch operation
• Improved shift response and reduced mechanical noise
• Maintains performance across a wide temperature range

What practical benefits can I expect during regular use?

Beyond peak-performance scenarios, this oil provides low oil consumption and long-term stability that prolongs drain intervals compared to conventional oils. It helps preserve engine components, keeps operation quiet and efficient, and supports reliable starts in varied climates.

• Reduced oil consumption thanks to optimized base stocks
• Extended ageing stability for longer effective life
• Consistent cold-start protection and hot-running reliability

Who is this for: Liqui Moly Motorbike 4T Synth 5W-40 Street Race is aimed at riders who demand racetrack-honed protection in everyday use — sportbike and high-performance street motorcycle owners, frequent long-distance riders, and anyone seeking a full-synthetic oil that maintains engine cleanliness, supports catalytic converters, and ensures smooth clutch and gearbox operation. Choose this 4-liter pack when you want a proven synthetic lubricant that stands up to intense riding while remaining suitable for street-legal machines.
