High quality part

Sunstar makes great stuff. The sprocket I received this time is made in Japan and very well made. These weigh less than other steel sprockets and last longer too.

Worth every penny

Bought this for my 09 yz450f in March and I ride at least two day a week. The sprocket is still going strong. Not real fancy looking and a bit heavy, but if you want something durable and cheap, this is the way to go. If you need a back sprocket, also need a front sprocket and chain to prevent any unnecessary wear. I went with a Tag front sprocket and a DID Xring chain. Good combo.

Works great!

I needed a higher top speed on my DRZ400E that I made street legal. I went down three teeth for on-roading, and I have the other for strickly off-road.

Durable and does the job

I've decide that I like the durability of steel over the lightweight of aluminum. I can honestly say that the extra weight does not make a difference in my lap times...har. Not changing sprockets every few months is definitely a plus to me.

Not bad. Heavy duty yet way lighter than stock. Seems to work good.

How many teeth can I install on my rear with my stock chain?
I counted 13t on the primary and read the stamp of 42 on the rear. I'm midway on my adjustment. How many teeth can I install on the rear without changing my chain?

You might be able to go up a tooth on either the front or rear sprocket (not both) but its hard to say. If your chain has lasted long enough for you to wear through a sprocket, you will want to replace the chain before it breaks and causes damage to your bike which can be costly if it does.

You will likely need a longer chain as well if switching from a 50 tooth rear sprocket to a 53 tooth.

If number of sprocket teeth is the same as factory you should be fine. If you're upgrading to the 53 tooth sprocket in the rear you may need to run a longer chain.

Looking for a sprocket 41 t?
Hi I have a Honda 2003 XR650R and I need to replace the sprockets , my front one has 15 teeth and the rear has 41 teeth . I have bought a DID 520 VX2 gold X-ring chain but need the sprockets, so could you please let me know if you are able to supply me with these sprockets. Thanks Graeme 0424100955

Unfortunately we do not offer a 41 tooth rear sprocket for the XR650R. We do have a Sunstar Available in a 39 though. You would need to run a 14 tooth front sprocket though to get close to the gear ratio of the 15/41. We do have a Sunstar 14 tooth front sprocket to make this gearing combo possible.
