Supersprox goes all out with their Rear Steel Sprockets, from first stage to last. Let’s start with the first. Supersprox begins by using a highly specialized SCM435 Ni-Chrome-Molybdenum low-corrosion type steel as the base material for the sprocket. Once the shape has been CNC machined, the sprocket is case hardened to give it a low carbon core and an incredibly tough surface hardness. To finish it off Supersprox uses hot-dip galvanizing to protect the surface of the sprocket by chemically creating a shielding layer of zinc carbonate. So what does all that mean? What it means is that you’re getting a sprocket with outstanding durability made from some of the best materials available.
I had the more expensive 2 piece sprocket on for 3 years. It's still serviceable along with the chain but it was at the end for this season. I also went up to a 50 tooth for better options in the woods. My old sprockets held up unbelievably
Decided to try a lower cost steel sprocket on my latest build, seen this brand and liked the reviews and looks. The fitment and durability so far has been great. It has already outlasted most sunstar stock ones I have had. Will continue to use these when the time comes.
I had the same issue with the sprocket holes not being drilled properly. They are off enough that I cannot even mount it on my WR450. It is the sprocket for my bike. I like the look and seem solid but I would check to see if it really fits. I think those holes need to be almost perfect. I think I will wait till next time I need a sprocket and order to see if they fixed the issue. Order at your own risk though.
The counter-sink angle on the bolt holes is slightly wrong, which means the bolts will eventually loosen and tear your hub apart. Fortunately, my mechanic is world-class and spotted this fatal flaw. I compared it to every other sprocket I have and he is 100% correct. Use at your own risk; in my opinion, this is a dangerous product and should not be sold until this is fixed.
This sprocket is the real deal. It is thicker than others I have used and it seems to be much more durable, it is an excellent product for the price. This sprocket is made in Poland not south east Asia.
These sprockets are tough. I ride in the desert mostly rocky single track stuff and put a beating on these sprockets. Whenever I check for wear there's very little other than the color being worn off. Super sprox makes excellent steel sprockets!
This sprocket held up extremely well with a lot of derailing due to a bad lower chain roller. Shows very slight wear after an entire season of racing. Only issue i had was the tapered mounting holes were slightly smaller than most other sprockets making my dual sprocket guard slightly wider and closer to the swing arm. If wasnt using the guard it would be fine and would buy again for sure. 05 Honda trx450r.
Like my review of the front sprocket. The rear is no different from the front sprocket. The quality has been the best ive tested. Ive been through alot of brands, renthal, sunstar, cheaper brands etc. This is the lightest and strongest steel one ive used. I used to run aluminum but they wear out so quick. Supersprox has a steel/aluminum sprocket that i have not tested to save even more weight but im not concerned about weight. These sprockets hold up to abuse that the other brands ive tested just wear out too quick.
Super durable and quality made sprocket, I could have gone through probably 10 aluminum sprockets by the time it wore out. Don't be one of the local track clowns who thinks because they have aluminum sprockets suddenly the small weight difference will make them faster; only experts and pros have the right to make such claim.

So strong and embraces abuse. Iv had this sprocket on my bike for 2 yrs now and just recently have I noticed some slight wear on the teeth. I will certainly buy this sprocket again. Its not too heavy either. Yes, it weights more than an aluminum sprocket, it will last 4 times longer though.

I had this sprocket for my 2012 KX450F which was a powerful beast. I liked it so much that I am going with this on my 2016 KX450F. It's heavier, yes, but unless you are a pro and someone is paying for your aluminum sprockets save yourself the money. You won't notice the added "unsprung" weight. You'll have more mud on your swingarm ten minutes after you jump on the track. Just buy it.
