Recommended sprockets manufacturers (?)

2007 KLR 650, I purchased a sprocket set last year, and while my chain has been a little loose, just noticed I only got a few thousand miles on the rear sprocket and now have outrageous wear - the previous sprocket got at least 4 times that. I conclude not all sprockets are of the same quality/hardness, and am looking for suggested parts manufacturers.

I suggest one only use a steel rear sprocket on your bike for durability sake. Sunstar, JT, PBI, Primary Drive are very good.

Chances are your cheap chain is actually as badly worn as the rear sprocket and the used front sprocket will probably make odd noise when used with a new chain and rear sprocket. And it will accelerate the wear of a new chain.

Use only o-ring, v-ring, x-ring sealed drive chains. I like RK, DID, EK, Renthal chains, with Clip Style master links, even if I have to order the clip style separately.

Modify at "YOUR OWN RISK"!

Still riding my 1987 KL650-A1. 85,000+ miles & counting

What is the brand of your current sprocket set?

JT and Sunstar all have good sprocket sets for the KLR. A lot of folks use the Primary Drive sets sold by Rocky Mountain ATV. Use them myself with no abnormal wear issues.

My Kaw Barn - 2004 KLR, 2006 Concours (sold), 1997 Bayou 400.
