Plastic Fuel Tanks

[LongRanger_imp]

I believe they're roto-molded nylon, not plastic, but it's best to avoid bikes with these things unless they're buried underneath other bodywork, for the reason Ferret identified. Moto Guzzi and Ducati both had significant issues with swollen tanks and had to issue worldwide recalls or honor warranty claims to replace them. Guzzi no longer uses them on the V7 line.
