Field of application
Cross Power 4T 10W-50 MA2 Six Days is intended for high-performance 4-stroke off-road motorcycles that specify a 10W-50 viscosity grade and require JASO MA2-compliant applications include:
- Motocross and supercross race bikes operated at high engine speeds.
- Enduro and hard-enduro motorcycles used in long, demanding special stages.
- Cross-country and rally-style off-road machines exposed to wide temperature ranges.
- High-performance trail and dual-sport motorcycles that share engine oil with gearbox and clutch.
Benefits in use
- Stable oil film helps protect heavily loaded components such as camshafts, valve trains, pistons and bearings.
- High shear stability helps maintain gearbox and clutch protection throughout the oil change interval, even under frequent gear changes and aggressive acceleration.
- Excellent thermal stability supports consistent oil pressure and viscosity in hot running conditions, such as slow technical sections or deep sand.
- Optimised friction characteristics support smooth, predictable clutch modulation and precise power delivery.
- Clean-burning formulation helps keep internal engine surfaces free from harmful deposits, contributing to long-term reliability.
