I've got three bikes with plastic tanks and I've had to line them all as the ethanol melts them. I also drain the tanks as soon as possible if the bike is being stored. The ethanol will attack plastic, glass fibre and rubber seals. I always fill will premium petrol which some manufactures claim to be ethanol free but they refuse to guarantee it. I understand there have been real problems with plastic tanks on boats.
