By the time mine had reached 2000mls I had changed oil/filter 3 times, nothing like erring on the side of caution, oil is cheap new engines are not.
I understand your caution, but apparently that is now 6 times more often than manufacturers recommendations
"To reduce the cost, Royal Enfield authorised service centres will start using a new process and new technology. The authorised service centres will now start the use of a new mix of semi-synthetic oil for servicing. This will increase the oil replace interval, which in turn will increase the service interval too.
Currently, the Bullet, Classic and Thunderbird range have a service interval of 3 months or 3,000 km. The new service interval will be 6 months or 5,000 km. It will significantly reduce the ownership cost, which according to Royal Enfield is about 40%.
T
he oil change interval will now be 12 months or 10,000 km, which is a significant increase from the current 5,000 km or 6 months period. The new strategy will help customers save a lot of money and Royal Enfield has estimated up to 40% savings over a period of 3 years. This new regime is applicable to all the bikes powered by the Unit Construction Engine motorcycles."
