JASO MA or MA1 is usually recommended for motorcycles with smaller cc. Most motorcycles require JASO MA2, which covers the most demanding applications. The more powerful the motorcycle, the higher the friction coefficient should be. Higher friction coefficient is needed to guarantee good clutch engagement. Always consult your motorcycle’s maintenance. Use with motorcycle with wet clutch will result in poor performance, though. Reducing frictional losses leads to lower operating temperatures in the engine, and higher fuel efficiency.Īll Repsol Action series MXR MATIC products come equipped with Matic Cooling Tech, and are the best option for your engine if you have a motorcycle with dry clutch. This means the gear oil will be optimized to achieve the best CVT performance, and the engine oil can be optimized for lower friction. Two different lubricants are used for the engine and the gearbox. Repsol Action Series lubricants, from MXR 5 and above, all meet JASO MA2, which means the gear shifting will be fast and responsive, even when high torque is required.Īutomatic motorycles (mostly scooters) use continuously variable transmissions (CVT) that are housed separately from the engine. The JASO standards regulate this property, and act as reference for all the industry. 
To counter this, lubricants for motorcycles with wet clutch are designed with higher friction in mind. This creates a complication since, what works best in the engine (lower friction), would cause the clutch to slip, making the gear shifting unreliable.
#Automatic motorcycle scooter manual
Manual motorcycles use a wet clutch, which means there is a single lubrication circuit for the engine, clutch and transmission.
