0 friction material on the disc itself
1996 1100GS with low miles (I think) I bought it as a non runner and it was accidented sometime in the past and a complete 1150 front installed. All seals, bearings etc and fine.
I'm thinking I want to try a VW airhead clutch disc.
Should I be changing all the clutch parts as the kit or can I refinish them or use as is?? No scarring from rivets
