Dont worry about the distance between services? Even at this sort of miles/klms it will be well within the oils capabilities. As the engine builds and engine oil get better these sort of gaps will get even larger. Oil never breaks down? its the additives in the oil and as these get better the longer the oil will last.
Dont waste your money put it into fuel and get the extra fun out of riding it.
I work in the automotive industry although on trucks these gaps are getting greater all the time. IE 150,000 klm between oil changes? This being almost annually and 4 times greater than it was 10 years ago. In time with good filtration and engine/oil development oil changes will be a thing of the passed.
Just keep an eye on the level and top up when required and let it do the

Ride safe
