Hi all, I normally use a Schuberth flip front with my autocom. I'd removed the speakers from the big backing plate, and recessed the small button speakers into the polystyrene. It was never loud enough with earplugs, even with a boosteroo. However, the Schuberth is now old and knackered, so I thought I'd fit it to my HJC trackday fullface, which is much newer and in better nick. I've had shoei's in the past, and the cheekpad and chin bar assembly just pulls out. Does anyone know if the HJC is the same? It seems pretty securely fixed, so I don't want to feck it up!
