well, here's a link to the best setup you can buy:
There is a lot of information on the subject at this website. Hardly anyone buys this setup because it's expensive. The chain will outlast your bike. well, unless you are running nitro at the dragstrip. It would be a good setup for a rider who makes a lot of long distance rides. It's too expensive for me and a little overkill imo. You did say the best.
Just take hammerheads advice
