Holds up very well. It's the only rear sprocket I use.

Looks even better in person!

Looks great and now have a couple rides on it and still love it! Can't really talk about durability yet but I'm sure it will last longer than an aluminum sprocket and with this unique design the weight difference is minimal. Well worth it to extend the longevity!

Very good product

Installed on 2014 CRF250R. Comes with new bolts/ nuts. It's very light and so far holding up well. I expect much longer life than the aluminum sprockets installed in the past. No reason not to use it!

Best sprocket- over 40 hours and no signs of wear

It's very thin so it's light. Teeth offset to compensate for standard width
Helps keep crud out too
it has no signs of wear after 40 hours in Florida sandy tracks
I used a good chain rk mxu as well
I've tried several other kinds this one is the best. Have not tried an ironman but for half the price you can't go wrong
Will definitely buy again when I need another one
Wore out front sprocket but rear still looks new

It looks pretty cool for a steel sprocket. wanted more longevity out of chain and sprocket setup. the teeth are offset from each other to clean mud out. it is heavier that aluminum. comes with new bolts and nuts

A: Yes. Sprockets fit all types of chains (non-sealed, O-Ring, X-ring). Just be sure to get the right size chain and sprocket so they match. ie: 520 for late model fullsize dirtbikes.
Q: Fit inside OEM chain guide?
Over 4 years ago
Since the teeth are offset, or kinda wavy... does it rub the original chain guide more? any mods needed to the stock chain guide?

A: Even with the teeth being offset, the sprocket is no wider than a stock/regular style sprocket. It will still fit in your chain guide and will require no modifications.
