Silkolene Pro 4 15W-50 XP 1L – Ester-Based Fully Synthetic Motorcycle Engine Oil (JASO MA2 / API SN)

Enhance your motorcycle’s performance and engine protection with Silkolene Pro 4 15W-50 XP 1L, a premium ester-based fully synthetic engine oil developed for high-performance 4-stroke motorcycles. Designed to deliver exceptional lubrication under extreme conditions, this advanced oil provides superior protection, smoother operation, and long-lasting reliability for both air-cooled and water-cooled engines.

Ideal for riders who demand maximum protection in higher temperature environments or under heavy engine loads, the 15W-50 viscosity offers enhanced oil film strength and durability compared to lower viscosity grades.

Advanced Ester Technology for Maximum Engine Protection

Silkolene Pro 4 XP uses advanced ester-based synthetic technology, which offers significant advantages over conventional oils. Ester molecules naturally adhere to metal surfaces, maintaining a strong lubricating film even during cold starts and high-stress riding conditions.

Key benefits include:

• Reduced engine wear and friction
• Superior oil film strength under high loads
• Enhanced protection during cold starts
• Improved engine cleanliness and reduced deposit build-up
• Extended engine life and reliability

Optimised for High-Performance 4-Stroke Engines

This fully synthetic oil is specifically engineered for modern 4-stroke motorcycle engines, making it suitable for a wide range of bikes, including:

• High-performance sports bikes
• Large-capacity touring motorcycles
• Naked and street bikes
• Adventure and dual-sport motorcycles

Compatible with both air-cooled and liquid-cooled engines, it delivers consistent protection across varying riding styles and conditions.

Superior Gearbox & Wet Clutch Performance

Motorcycle engines typically use a shared oil system for the engine, gearbox, and clutch. Silkolene Pro 4 XP is designed to excel in these demanding environments.

With JASO MA2 approval, it ensures:

• Smooth, precise gear changes
• Reliable clutch engagement
• Reduced clutch slip under acceleration
• Improved riding comfort and control

15W-50 Viscosity – Ideal for High Temperature & Heavy Load Riding

The 15W-50 viscosity grade provides enhanced protection compared to lighter oils, making it ideal for:

• High-performance or high-revving engines
• Hot weather riding conditions
• Long-distance touring
• Bikes that run at higher operating temperatures

Viscosity Breakdown:

• 15W (Cold Start): Maintains good flow during start-up for reduced wear
• 50 (High Temperature): Thicker oil film provides superior protection under heat and stress

Cleaner Engine & Improved Efficiency
