  When it comes to selecting the right oil for your vehicle, especially if you own a motorcycle or a vehicle with a wet clutch, understanding the JASO oil classifications can be crucial. These are some guidance on which one might be best for your vehicle: JASO Oil Classifications 2-Stroke Oils JASO FA: This is the lowest 2-stroke oil specification. It tests for lubricating capability, detergents, initial torque, exhaust smoke, and exhaust system blocking. JASO FB: This specification is a slightly higher standard than JASO FA, with increased requirements for lubricity, detergency, exhaust smoke, and exhaust system blocking. JASO FC: This spec has the same level of tests as JASO FB for lubricating capability and initial torque, but with far higher requirements for detergency, exhaust smoke, and exhaust system blocking. 4-Stroke Oils JASO MA: This oil is designed for motorcycles and other vehicles with a single oil system for the engine, gearbox, and wet clutch. It does ...

  Hey there! So, you’re curious about why sports motorcycles use wet clutches? Here is the reason: The Basics: What is a Clutch? First things first, let’s talk about what a clutch actually does. In simple terms, a clutch is a mechanical device that engages and disengages the power transmission from the engine to the drivetrain. Think of it as a bridge that connects the engine to the wheels. When you pull the clutch lever, you’re essentially lifting that bridge, allowing you to change gears smoothly. Wet vs. Dry Clutches: What’s the Difference? There are two main types of clutches: wet and dry. A wet clutch is bathed in oil, while a dry clutch operates without any lubrication. Each type has its own set of advantages and disadvantages, but sports motorcycles predominantly use wet clutches. Why? Let’s break it down. Cooling and Lubrication One of the biggest reasons sports motorcycles use wet clutches is cooling. When you’re riding a high-performance bike, the engine and t...
