Perfect fit, durable, affordable. Proper maintenance and you will get good life out this sprocket.

Bought this as an inexpensive replacement for my sons bike and it seems to be holding up pretty good.

-m-2000 KAWASAKI KX100--

Works great and perfect fitment. Definitely a quality product

Primary drive from Rocky Mountain is the best deal you can get on good quality sprockets

Heavy duty sprocket at an incredible price. Haven't ridden with it yet but it's price alone makes it hard to pass up. Only giving it one star because I haven't used it yet.

-m-2006 SUZUKI RMZ450--

works as it should. mounts right up. lasts forever. nothing fancy but function over fashion

-m-2017 KTM 350 XC-F--

I really like primary gear sprocket I redo bikes for kids and they last a really long time so if you're not a professional and don't mind adding the extra weight their top-of-the-line

Great sprocket for the price. Little on the heavy side, but last forever. Can't go wrong on the track or in the woods.

I bought a driven 45t steel sprocket for my Xr650l. It is way heavier and has much more metal in it than the JT equivalent. So much that I didn’t bother installing it. It is also designed with multiple mount patterns. This is probably to save cost but adds a lot of weight. If you want a steel sprocket for your Xr650l and don’t want to add considerable weight. Consider something else.

-m-2002 HONDA XR650L--

Great sprocket for the price, over 20 hrs on mine still looks fresh.

The sprocket is strong, easy to install, well built, and does what it is designed to do.

-m-2004 YAMAHA WR450F--

Great product never any regrets order anything good fast shipping and great quality

I ride hard! Primary Drive sprocket out last renthal, this is steel so as long as your not trying to reduce overall bike weight buy this one! Must bang for your buck!

I’ve been using the primary drive sprockets for xc racing for 5 years and have had 0 failures. Great product for less money.

Nothing beats these sprockets for the money. Durable as all get out, cheap, and good fit. Sometimes the outer coating peels off, but that doesn't matter to people that buy $20 sprockets. We just want something durable and cheap.

if you don't want to spend too much and you don't mind the weight this sprocket is great

I had read online that a lot of people have change the gearing on my particular motorcycle, a 2013 WR 250 R. This rockets really changed the entire bike and how it handled out in the desert from the start hearing. The price was good easy to install and it really changed the entire bike. I highly recommend these products

-m-2013 YAMAHA WR250R--

Fit and performance are excellent. looks good too.

-m-2008 HONDA CRF450R--

Fits perfect, I changer both sprockets and the chain at once per recommendations online and haven’t had any trouble at all. I geared olio a tooth on the front and it made a lot of difference, very nice on a gen2 KLR anyway.

-m-2015 KAWASAKI KLR650--

I would recommend this item to any one I use a lot of their parts and they never let me down well made products for your bike out there and they have a lot to choose from for your needs put their parts to the test at every race

Sprocket has held up very very well over a year period and is still going strong

Perfect fit, seems just as durable as OEM, if not more. I have a few thousand miles on it so far and notice no irregular wear. My only complaint, I wish they had it in black.

-m-2012 KAWASAKI KLR650--

It's one of the better sprockets on the market and price-wise you can't beat it they're much tougher than aluminum ones

-m-1986 HONDA TRX 250R FOURTRAX--

Quality sprocket for cheap, fits great only have 20 miles on it so far

Great sprocket at a fraction of the cost.

-m-2007 KTM 300 XC-W--

Great quality and price, fits great and came with both sproket bolt patterns

i got this sprocket a while back for a 2007 klr650 and after about 1000 miles of not particularly gentle use (a couple of parking lot wheelies come to mind) i noticed it starting to twist. out of pure curiosity and disregard for the rest of my drive train i decided to see how much farther i could push it before i just couldn't run it any longer. i wound up making it to an estimated 1500 miles before i deemed it unusable, it was missing half the teeth if not more, warped entirely around the chain to the point that the chain was clicking in to the sprocket and then clicking back out like a seat belt instead of just a smooth in around and over. over all for $11 i'm impressed that it went this far, the install was seamless, but as compared to how a more expensive sprocket would last it really wasn't that long. the only real use i can think of for it is to throw a cheap but functioning part on a bike you're about to sell just to make it look a little better than a sprocket with 5,000 miles on it and maybe get a little more money for it, though doing it would make you an absolute cur. the best comparison i can make would be a fast food burger, for the price it's alright, but it will never really compare to something that you spent a little more money on.

awsome value very durable would recommend this for sure

-m-2018 KTM 250 XC--

I realize this is the "cheapy" version of this sprocket so like what do I expect.
It weighs about 3 times what the manufacturers original weighs.

Replaced the broken sprocket on my 05 crf250r with this one and it looks and fits great!

-m-2005 HONDA CRF250R--

Just as it is in the description, the fitting was just perfect.

-m-2004 KAWASAKI KFX 400--

longevity is typical for aluminum sprockets. fit was perfect. performance was typical for a sprocket. lol finish was excellent. looks nice

Good quality rear sprocket, I would reccomend because of the value and the quality, very good product that will save your wallet.

Fits well, looks really nice, held up well to sand, better than aluminum by far

-m-2004 YAMAHA YFZ 450--

Factory gearing is poor on rally this fits as good as o e m. Quick shipping item as discribed
-m-2018 HONDA CRF250L Rally--

This is a really durable rear sprocket at a very good value would definately order anouther from rocky mountain atv again

Bought this to give the WRR more low end for tractoring around in the woods. Bolts right up, no new bolts needed as it has both style holes. Went from stock 13/43 to 13/47. Bought a 120 link chain so that I would have enough links to use stock chain later on as bike was new.

-m-2017 YAMAHA WR250R--

I went to a 48 tooth from the stock 45 on my XR650L. For my purposes it really works great. No problems with fitment, seems well made.

-m-2017 HONDA XR650L--

Can't beat the price on these. Got this sprocket as part of a sprocket and chain package. Both sprockets and chain for the price of just the chain from DID for example. I'm not a racer just a casual rider the extra weight doesn't bother me at all.

-m-1996 HONDA CR250R--

For the price it is a good sprocket. If you are a trail rider or weekend warrior this will work for you!

Got this sprocket to replace a worn out renthal and the fitment was better than the renthal, and a quarter of the price

Long-lasting and durable sprocket does the job and does a good

If you are not concerned about the weight of your sprocket, then this one will be fine for you. It weighed in at 3.4lbs in the package. I sent it back and bought a lighter weight steel sprocket. Didn't mount it. Not rating anything but the weight of the part.

-m-2013 YAMAHA YZ250F--

Very nice sprocket and seems to be holding up well, you can’t bet the price, as good or better then the oem

I have a few rides on this sprocket, seems fine and fit well. I want my race bike to be a trail bike and so the 51 tooth rear combined with a 12 tooth front replacement has the tractor effect I needed.

-m-2017 KAWASAKI KX250F--

fit exactly, and its the same thing to the oem sprocket

Great option easy on the pocket, fits perfectly and has done many hours for me so far

Why spend big bucks when this steel lasts longer than the others

-m-2015 KTM 300 XC--

Bought a few of these to play with gearing to find what works best. Cheap enough so I don't mind buying a few to get the perfect setup.
