Using synthetic oil for the first service of your Honda Hornet 160R can be a suitable choice. Synthetic oils typically offer better performance and protection compared to conventional oils. They have superior resistance to breakdown, enhanced lubrication properties, and improved temperature stability.
To ensure compatibility and optimal performance, it is always recommended to consult the owner's manual or contact the authorized service center for your motorcycle. The manufacturer provides specific recommendations for oil viscosity, grade, and brand that are best suited for your motorcycle model.
It's worth noting that using a different brand of full synthetic oil, such as Honda's full throttle synthetic oil, shouldn't be an issue as long as it meets the manufacturer's specifications. However, it's essential to verify compatibility and suitability for your specific motorcycle model to avoid any potential problems or warranty concerns.
Consulting the owner's manual or contacting a Honda dealership or service center would be the best course of action to get accurate and up-to-date information regarding the recommended oil for the first service of your Honda Hornet 160R.
