depends on what sort of rims your looking at excel ones would be expensive but of very high quality so its up to you what change you would do to the MSX200-II. on my supermoto i have cast wheels which would be cheaper perhaps to get than spoked wheels if you wanted to do a change, i would check the bhp/kw ratings for each bike to see what offers the most power but these are probably taken in a colder climate so may differ in the phillipines normally i would say go for liquid cooling but liquid cooling does mean more parts to go wrong than a air-cooled bike.

also going to see the bikes in person will also give you a better opinion on quality and just the general feel of the bike with your weight on it, i understand what you mean it took me two years of looking to upgrade motorcycle and i'm really happy with my bike but time has come to change it next summer for me.
