PRIMARY DRIVE Brand Sprockets?

[MP-44]

I found them in the Rocky Mountain catalog. Are they any good?

I put them on my KX with a Renthal RK1 chain about 2 months ago. So far so good. A friend put the same combination on his RM250 last winter and he is still running them with no problems.

Thanks! I think I will try them out.

I ordered a steel rear sprocket and it rounded the teeth on the first ride, they sent me out another and it did the same thing. I dont think they got hardened or something. Personally I would go with Sprocket Specialists alum, they have held up well for me and my buddies.

i've used them on my and the kid's bikes with good results. For the $$, they're a good deal.

If the teeth of your sprockets kept rounding it is probably because you are using a worn out chain. Always start fresh with new chain and sprockets for best wear. And realistically, a lower priced steal sprocket will out last an alluminum one. Ever wondered why they don't make alluminum counter shaft sprockets?
