Aftermarket Gas Tank – This is a reproduction gas tank for the 79-87 Z50Rs. The quality of the tank is very good and they look real nice, however the paint quality is not that of a Honda tank and slight imperfections are possible. They are a nice alternative to the more expensive Honda tanks for those who aren’t restoring their Zs. They also come with a gas cap more like the original one (not a locking gas cap like others include with similar tanks) and a petcock.
