On the MX KTM sprockets fit. So you have the range of 12-15.

I dislike the Stark ones, they are aluminium with holes drilled tru. They wear very fast and i know some people who actually were able to break them in 2 on hard landings with open throttle, in 1 case bending the drivertrain axle by locking up the chain.

I always buy aftermarket steel ones. Longer lasting, not breaking and cheaper.
I never buy aftermarket front sprockets because I fear that they may damage the countershaft because of some characteristic of the splines. For example, the splines may be too hard or have an excessive shape error or the wrong play.

Does that really matter on the lifespan of an MX bike though?

Also this is not a circlip mount, but a solid bolt connection. I never seen damaged axle splines on a bolt mounted sprocket. I have seen it with circlip sprockets with both OEM and aftermarket. I think it's more a design feature than a actuall sprocket issue.

Now that I think about it, I've seen it on circlip mounts as well; probably you are right.
