Use a 530 O ring chain that has a good tensile strength rating. Some repuable brands are RK and DiD. Spending a little extra for a good strong superior chain is a good solid investment for that added security for lasting longer and prevention of chain break. Be sure that it is put together correctly. A bad master link can ruin your day. (I just saw this last week on my buddies 2006 CBR where his chain failed while riding 70+) Definitley change your sprocket and counter-shaft sproket when changing your chain. The reason is because they all wear sysmetrically together. Putting new chain on old sprokets only will cause premature wear of your new and cause extra vibration as well. There are plenty of sprokets out to choose from made from different materials and coming in different colors. Chosing a sproket depend on what you are trying to acheive. For durability, you can't beat steel. For performance, you can select aluminum alloy that is much lighter. The main draw back of using aluminum is it will wear down faster than steel. The countershaft sproket will always be a high grade steel due to the amount of torque and stress that it takes on for being such a small part. Hope this helps.
hey JR; Wouldn't it be better to use an x-ring chain, I believe they have less drag than than an o-ring style. Also I would recommend a good heat treated aluminum rear sprocket, they are almost as good as the steel but a bunch lighter.And you can get them in colors to match your bike. tks eddie cap
