Often manufactures will do a software upgrade that can help the performance of their machinery, so if you never have your vehicle serviced by a authorised dealer you could be missing out on some upgrades, this is another reason BMW want you to hook to their system.
A friend of mine purchased a Yamaha from his friend, it had always been serviced at home, I recommended he have a service done at his local Yamaha shop, the bike had missed out on 3 software upgrades and after the upgrade the bike preformed much better.
Paying full wack for a service or getting to know someone in the service department that can tell you when a service bulletin has come out for you particular bike can help with performance and the longevity of your ride.
PS; I don't take my own advice, I do all my own mechanical and electrical work at home.

Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
