Liqui Moly Motorbike 4T Synth SAE 10W-50 4L — Fully Synthetic 4-Stroke Oil for High-Performance Street & Race Engines

Liqui Moly Motorbike 4T Synth SAE 10W-50 Street Race is a fully synthetic 4-stroke motorcycle oil formulated to deliver dependable lubrication and wear protection for high-speed street and race engines.

Designed for modern high-performance motorcycles, this 4L pack of 10W-50 synthetic oil provides stable viscosity at elevated temperatures and is suitable for both road and competition use. Its formulation supports oil-bath wet clutches, helps maintain engine cleanliness, and has been tested for compatibility with catalytic converters. Liqui Moly engineered this grade to offer low consumption, high shear stability, and the protection required for stressed engines operating under extreme conditions.

How does this oil protect high-revving motorcycle engines?

The synthetic base and robust additive package resist thermal breakdown and shear, so the oil keeps a protective film even during prolonged high-speed runs. That reduces metal-to-metal contact and minimizes wear over time.

• High shear stability maintains viscosity under load
• Enhanced wear protection for critical engine components
• Ageing-resistant formulation reduces oil degradation

Can I use it with my bike's wet clutch and catalytic converter?

Yes — the product is formulated to be clutch-friendly for oil-bath systems and has been tested for catalytic converter compatibility, so it suits modern street bikes with emission controls and bikes that rely on wet-clutch engagement.

• Suitable for oil-bath wet clutches (JASO MA2 compliant)
• Catalytic-converter-tested to help preserve exhaust systems
• Compatible with common commercially available engine oils

What performance specifications and approvals does this oil meet?

Liqui Moly Motorbike 4T Synth 10W-50 meets industry-recognized specifications to ensure broad suitability across many motorcycle types. These approvals indicate the oil has passed tests for engine protection, cleanliness, and performance under demanding conditions.

• API SL level for gasoline engine protection
• JASO MA2 classification for wet-clutch compatibility
• Formulated to maintain engine cleanliness and low consumption

How do I know when to choose 10W-50 for my motorcycle?

SAE 10W-50 is chosen when engines run hot or are tuned for higher power, where enhanced high-temperature viscosity is beneficial. It is a practical option for riders who mix road use with spirited or track riding and need stable protection under heavy thermal and mechanical stress.

• Preferable for high-stress, high-revving engines
• Good choice for mixed road and racing duty
• Useful where manufacturers or conditions call for higher hot-end viscosity

Who is this for: Liqui Moly Motorbike 4T Synth SAE 10W-50 Street Race is intended for riders and mechanics of modern 4-stroke motorcycles and racing machines that require a reliable, high-temperature-stable synthetic oil. It suits owners of sport and performance bikes that use oil-bath clutches, teams and track-day enthusiasts who need low oil consumption and strong wear protection, and anyone seeking an oil that is compatible with catalytic converters and common engine oils. If your motorcycle manual recommends 10W-50 or you push the machine hard on road or track, this product provides a purpose-built balance of lubrication, cleanliness, and component protection without compromising clutch feel.
