This is by far one of the most important deciding factor of your motorcycles life and mileage.how you maintain your bike for the first 1500 kms.
I personally maintain the following things. Please note that this is my personal opinion and I am not liable for any damages caused.
Change the engine oil of the bike within first 100 kms. Yes I typed it correctly, 100 kms only. This change is required if you want to get better mileage.
Drive your bike for 700 kms now within a speed limit of max 60 kms per hour.
Your first service should be done by 750 kms when you again need to replace the engine oil for the second time.
Stick to the company recomended oil.
After you completed riding 1500 kms, dnt suddenly push the engine to redline. Slowly make it accustomed to greater speeds.
After 5000 kms of riding you can switch to a semi synthetic or full systhetic oil depending on your bikes oil grade.
Hope this helps.
