Current motorcycles often use the same lubricant for engines and wet clutches. To make sure that the correct lubricant is used by the manufacturer. Lubricating oil must meet the requirements of JASO standard. Targets JASO MA JASO MA1 JASO MA2 JASO MB Dynamic friction characteristic index (DFI) 1.45 ≤ DFI <2.5 1.45 ≤ DFI <1.8 1.8 […]

What is foaming? Foaming assesses the degree of foam formation and destruction in oil. In liquids (hydraulic oils, engines), the air exposure range typically contains 8-9% dissolved air. When oil is in the air and foaming, it will increase the oxidation of the lubricant, increase the flow of oil and cavitation will appear. Most of […]
