Anyone know about kg clutch factory or supersprox?

[Fj1100 Rebuild project]

Hi again, my bike has some old stickers one says kg clutch factory and the other says supersprox... does anyone know what that means? Thanks

Probably some scratches underneath.

I can answer for the SuperSprox. I know the company for supplying sprockets. They have a Steel/Aluminum hybrid sprocket that is labeled as the Stealth line. I just ordered one for my Streetfighter project.

In the photo, the Blue section is Aluminum and the Black section is Steel.

Interesting, is the sprocket set up like that to reduce rotational mass?

superspox sprockets recommended been using for 7 or 8 years on my s1000rr - very good

KG is an aftermarket source for clutch plates.  I think they were well regarded in drag race circles - but I have no direct experience with them.

Good to know, hopefully that means the clutch could have been rebuilt once or twice, the bike has 50k miles and I'm really not looking forward to clutch work lol

If it wasn't abused, original clutch would still hold. Maybe it was upgraded anyway.
Clutch work on an FJ is super easy. Not cheap, though.
