Topic: Who sells quality hardened steel rear sprockets in different tooth ranges ?

[grcamna2]

I've purchased JT steel rear sprockets and they don't last as long as the Made in Japan quality hardened steel like  OEM Honda;vintage steel Sunstar isn't always available.I would like to get the good quality steel rear sprockets in different tooth ranges.
What worldwide company besides JT sells them and who is a supplier here in the USA ?
The Sprocket Specialist company is 90% alloy(they don't last half as long as steel)rear sprockets and the few decent quality steel rear sprockets they sell are only in the standard tooth range.

Probably a bit late now, but I recently bought a front sprocket for my Kaw from a company called Niche based on advice I was given. Evidently, it's a top brand among racers.

 I looked up niche and for a cb750k front sprocket the brand listed was Emgo.

Niche is one supplier of different parts which includes sprockets.I need to find another manufacturer of only sprockets especially steel rear sprockets(they last Much longer than aluminum)in different tooth ranges besides stock.I've bought steel JT rears of different sizes and they're one option,although they seem to wear-out quicker than a company like Sunstar steel rear sprockets.I think some of the large sprocket companies I've found so far(I don't know of many)are limited in their varied tooth ranges of steel rear sprocket offerings;this is what I know so far and I'm still looking for a quality manufacturer of steel rear sprockets that I haven't found yet who has varied tooth size steel rears for vintage street bikes,thanks.

Vortex is another company that sells steel sprockets.

 I bought a bike once with a plastic rear sprocket. It had been on there a while, not sure on the miles though. It was quiet when rotating the rear wheel. I'd bet today's plastics would be even better.

Just bought a chain & sprockets from SprocketSpecialist.com on 4/4/21, today while installing new tire and noticed that after 2,750miles the rear sprocket is totally worn out. The chain also did not come with a master link! Had to wait a week for that.
They definitely have gone downhill over the years.

Not going back there again, even though 10 years ago I bought at least 15 sets of chains & sprockets for my rebuilds.

I'll check these guys

  I bought the bike for a member out of country, kept it and later passed it along. I never licensed it. The PO loved it and said it had been on for decades.
