i am looking for a really strong long lasting chain and sproket setup

 

if you do upgrade your sprockets make sure you do both front and rears at the same time. i remember someone tell me taht the harder metal on one will increase stress on the other and wear it out quicker. as far as chains i use DID or RKO. make sure you use an o-ring chain.. you'll get more longevity

 

Try this site. They are a little pricey, but worth every penny. They also deliver REAL quickly.

I always get my chains and sprockets from Rocky Mountain. The DID and RK chains seem about the same to me. I have used the cheap Primary Drive sprockets they sell and they are OK, maybe good for 1 season of duning. I can tell that they aren't as good as the stock sprockets or some of the better brands. No need to spend $40 on a sprocket, there are some in-between brands that are OK. Sunstar seems OK, and lasted longer than the Primary Drive.
