On the surface it looks like it costs more. OEM is 60 plus 22 shipping (this is my complaint). The bando belt is also japanese made and retails for 69-71 however you can search around and find it for as low as 61 including shipping. I tried a well recommended gates belt that fell apart on me in 10 miles, i like options so thats ultimately the search. I know most are trying to save money i am too but its not the number one driving factor.
I side thought, this particular belt says 250 and you need the JB1 for s250. Upon digging around calling a few shops and kymco themselves the only difference between the two is this one is 976mm and the JB1 is 977mm. Since the cost of the JB1 is a bit more i figured I'd give it a try, 1mm is so small i figured it wouldnt make a difference.
