I'm looking for one as well, since the new engine coming for the Tenere is an 'Aprilia' motor. I thought about swapping the clutch covers but I'm really tempted to leave the Aprilia logo'd clutch cover on just for effect, like making a mini statement, (if I pull the swap off), but still requiring the extra protection.

You can just make out a 'witness' mark on my Yammy clutch cover where the brake pedal kissed it in the past. So in the spirit of tidying the bike up I need that protector in either case (pun intended).
