Great for the value.
I've had over a year with this set up so far and over multiple rides. Everything has held up great, I haven't noticed almost any wear at all on the chain or sprockets. Once this wears out I'll be buying the kit again. A great value for the price.

New chain, and sprockets
What can I say... looks like great quality, fit perfect, rides smooth after the install. The aluminum one I had before looks pretty worn, hoping the steel will hold up better.

I was pleasantly satisfied with this chain and sprockets kit. The kit lasted me a little over a year and the chain didn't stretch fast.

Very solid for price.
I have yet to put these on my bike hence only a 4 star rating, but they look very solid and fit exactly to OEM specifications. I was very impressed with how fast Rocky Mountain got them to me which is making lean more toward them for future purchases rather than Motosport.

Primary Drive chain/sprockets
Primary Drive chain and sprocket combo is the best deal around! Strong o-ring chain and steel sprockets provide long life with very little stretch. Always a good choice.

Do you reuse the bolts for the rear sprocket, or does it come with new, or do I need to buy new ones?
Steven K on Feb 28, 2017
BEST ANSWER: It does not come with bolts. I have never replaced the bolts. I have probably gone through at least 2 chain and sprocket sets in the 12 years I have had this 2000 KTM and a couple more on the Honda I had before and never had a bolt problem. I do use loctite on them.
what is the best way to choose a chain and sprocket kit with so many types and brands ?
A shopper on Feb 3, 2017
BEST ANSWER: If you're looking for longevity, and low price, this is the way to go. If you care about looks, weight or running other than stock gear ratios, keep looking. Best way I've found without trying them is to find a good forum for the tyoe of riding you do and ask there. You'll get a wide variety of opinions but, you can generally get a feel for what will work for you. This is a good quality basic set, I've used them for years and have no complaints. If you find out you need a lower ratio, you can get a smaller front sprocket for about $9
