Repsol Smarter Synthetic is a highly regarded oil for modern gear-shift motorcycles.

1. Operating conditions of gear-shift motorcycle engines

As our daily companion, we sometimes fail to fully understand the vehicle we ride every day. In reality, gear-shift motorcycles, often referred to collectively as bikes equipped with wet clutches, have distinct characteristics compared to scooters not just in appearance, but also in structural components.

Gear-shift motorcycles comprise several assembled components, prominently featuring the engine, wet clutch, and gearbox. These motorcycles use a power transmission system through oil-lubricated gears and clutches. Therefore, the primary function of the oil is to lubricate the engine and clutch, ensuring smooth operation of the machinery.

Thus, pay attention to the oil’s viscosity; low viscosity oil may not create sufficient friction, leading to overheating and clutch slippage.

2. How to choose oil for gear-shift motorcycles based on what criteria?

Due to frequent operation under harsh conditions and continuously changing weather, oil for gear-shift motorcycles must not only provide effective lubrication but also meet the following criteria:

• Heat resistance: This is the first criterion you should consider when purchasing oil for modern gear-shift motorcycles. To ensure the oil performs effectively and stably at high temperatures, it is best to choose synthetic oil. For older models that have been used for a long time, you may prioritize mineral-based or semi-synthetic oil products.
• Fuel efficiency: To purchase fuel-efficient oil, you need to pay attention to the API standard. The quality of the oil is rated progressively from SF, SJ, to SN. The higher the performance level, the better the fuel efficiency. For gear-shift motorcycles, you should choose oil with an API rating of SJ or higher. If mainly used in urban settings, you can use oil with a rating of 30. However, if used for long-distance travel, prioritize oils rated SAE 40 and 50.
