I've been doing some research since I saw this. The K413 for my bike has a load rating of 56 which is totally at the lower end of the spectrum.

I just sprung for a lot, by my standards, for the Vee Rubber which has a load rating of 66 and is built in Thailand. The Shinko SR-425 has the same load rating and cost enough less to make me consider it for my next tire.
As an aside, back in 2010 I bought a Cheng Shin for my 150cc for like $16, but $23 shipped. I have 5,500 on it and it should be replaced soon. Too bad they don't sell here anymore, it would be on my scooter again.
