If you are not a loyal kind guy. Then I understand why you would buy second best products. Why would you spend over $300 on a chain and sprocket set-up? If you buy a different brand bike a year or two down the road.. Totally agree with you there. But, If you a loyal brand kinda guy like me. I am different. I bought my SideWinder chain and sprockets for a 1998 CR500 in I beleive 2002. Well guess what, Those verry same Chain and Sprockets are now on my 2010 CR500af. How much money did these sprockets save me. I do not know but, I can say I bet your chain and sprockets would be toast on even your bike after a year or two. Renthal sprockets are fine if you are in a pinch. They will only last for maybe four or five hard rides. These are the bikes the same sprockets have been on. First one was the 1998 CR500 second was the 2000 CR500 and finally my current bike a 2010 CR500af. I will try and post pics of my rear sprocket this weekend.
I do plan on buying a different size rear this summer. It will be a SideWinder Ti-Molly II rear 48 tooph. Oops I mean TOOTH.
Stainless and Ti- Molly are stronger than steel.!
No matter how you shape the sprocket.!
I want the strongest, longest lasting sprockets money can buy.
Not to mention they were also on Doug Domokos bikes.
