Silkolene Pro 4 10W-40 XP 4L 

Maximise your motorcycle’s performance and engine longevity with Silkolene Pro 4 10W-40 XP 4L, a premium ester-based fully synthetic engine oil engineered for modern 4-stroke motorcycles. Designed to meet the demands of both everyday riders and high-performance machines, this advanced formulation delivers outstanding protection, smoother operation, and long-lasting reliability in all riding conditions.

Supplied in a convenient 4-litre bottle, this option is ideal for full oil changes, workshop use, and riders who want excellent value without compromising on quality.

Advanced Ester Technology for Superior Engine Protection

Silkolene Pro 4 XP is formulated using cutting-edge ester technology, which offers significantly improved lubrication compared to conventional and semi-synthetic oils. Ester molecules naturally bond to engine components, providing a continuous protective film—even during cold starts when most engine wear occurs.

This results in:

• Reduced friction and wear on critical engine components
• Improved oil film strength under extreme pressure
• Enhanced protection during cold starts and high temperatures
• Longer engine life and improved reliability

Designed for Modern 4-Stroke Motorcycles

This fully synthetic oil is suitable for a wide range of 4-stroke motorcycles, including both air-cooled and liquid-cooled engines. Its balanced formulation ensures consistent performance whether you're commuting in traffic, touring long distances, or riding aggressively.

Perfect for:

• Sports and superbikes
• Naked and street bikes
• Touring motorcycles
• Daily commuters
• High-performance engines

Optimised for Gearboxes & Wet Clutch Systems

Motorcycle engines often share oil between the engine, gearbox, and clutch. Silkolene Pro 4 XP is specifically developed to handle these combined systems, offering excellent protection and smooth operation.

With JASO MA2 approval, it ensures:

• Smooth and precise gear changes
• Consistent clutch engagement
• Reduced clutch slip under load
• Improved rider control and comfort

Reliable Performance Across All Temperatures

The 10W-40 viscosity grade makes this oil one of the most versatile and widely recommended options for motorcycles:

• 10W (Cold Start Performance): Ensures rapid oil circulation during start-up, reducing engine wear
• 40 (High Temperature Stability): Maintains strong lubrication at high operating temperatures, even under heavy load

This makes it ideal for year-round use in UK riding conditions.
