With my older yamaha tenere's the manual said every 6000km so i changed it that often (with a new filter each time). With the new pony it is probably the marketing department that has asked to have it increased to 10000km.

I've not been riding it that much and also stick to the old thumb rule of replacing the oil once a year - preferably just before putting it away for the winter.

I'll just stick to the manual with up to 10000km between oilchange.

But if you go for a rtw ride or are rallying it is aways nice to start with fresh oil and have the old checked for metal ...
