Just looking for a little feedback on brands of chain and sprockets that are durable and do not wearout quickly. I ride motocross only and prefer a steel rear over aluminum. Can you fellas give me a little feedback on what has lasted for you in this area. Anything on chains would be appreciated as well. I am currently running the supersprox rear, although good, they are pricey. Any gearing changes you have had luck with would be good to know as well. My bike is a 2009 450SXF. Thanks!
