Way back in this forum's history there was a guy who proudly spoke of the fact that he changed his oil every 600 miles. On the other hand, I change my oil according to what the owner's manual says with the cheapest motorcycle 10W-40 I can find locally. It has now been 9 years and just about 30,000 miles and things are still going well.
I have not heard of any major lubrication-related failures on the Versys. As long as that is the case, then I think that you can be a bit lazy with your changes. On the other hand, some people really like changing oil. The cost difference is not that great either way.
