I'm having trouble finding replacement rear 42T steel sprocket. The biggest I've found is 40T. Anyone know of a source, I've tried Sprocket Specialists and a bunch advertising in magazines, but no cigar. Even a blank is acceptable, I can machine the bolt pattern and open the bore. The sprocket I'm replacing is bare aluminum but didn't seem to last very long, maybe 11k miles. Do the hard coated anodized sprockets last longer? TIA

Check with ncrick on this site. Send him a pm or go to his web site www.motocd.com
He is a supporting vendor and was able to get me a pretty good price on a chain and sprockets for my ST, I know that he deals in Afam. These are very good sprockets, my current set has over 20,000.

Thanks Butch, I'll give Rick a call. Anyone else comment on the lifetime of anodized sporckets?

Give Ducati Seattle a call. Ask for John in parts. They have never had a problem gettting a 42T sprocket for my ST4s. My chain usually lasts about 16,000 miles and the steel sprockets still look good, although I replace them anyway along with the chain.

Ducati definately will be able to get you a 42T steel sprocket. It's OEM on the ST2 and ST3. My set is 8 years young and close to 28,000 mi. and I think it's just about time for a replacement.
