Dirt bikes have had plastic tanks for a long time. My Yamaha XT225 came with a 2 gallon steel tank. I replaced it with a Clarke 4 gallon plastic tank. But it is a dual sport bike used mainly as a dirt bike. A cruiser might look a bit odd with a plastic tank. I still wax the paint on my cruisers. But a bigger concern would be ethanol. I had the oem tanks on 2 Honda dirt bikes destroyed by ethanol. It happened while they were sitting in a shed with ethanol gas in them. I went in the shed and could small gas. I looked at one of the bikes to see if there was a leak. I rolled it outside and discovered the tank had cracks all over it. I checked the other one. Same thing. Both vents were open, so it wasn't pressure. The ethanol broke down the structure of the plastic tanks. When I'm not going to use my XT for a while, I remove the tank and flush it out with water, and drain the carb. A 4 gallon Clarke tank is about $300 bucks.
I am a motorcyclist, NOT a biker.
