With economy being a consideration, it might help you to know my servicing costs. At miles I needed a new rear tyre.
I started DIYing the servicing after the 12k service. My fuel economy hasn't dipped below 70mpg at any time.
A lot of my riding is 2-up at 70ish mph, so quite hard on the bike, and I personally find a mile service interval to be unacceptable, the performance is noticeably deteriorating by this point so I am changing oil every miles.
