Ceramic clutch disc have a horrible wear life. You cant expect to see anywhere close to 100k miles on them. Your not running much power so I would definitively go with a kevlar clutch. They have very smooth engagement and last a long time. I have personally ran several Zoom clutches (Advance sells them) and have never had a problem. Best thing about kevlar is even if you burn it down the track, once it cools down its back to normal, wont glaze or burn up. I am currently running stg 4 sintered iron disc.
