Wondering if a plastic 800 S2R tank will work on a 2002 M750 without any modifications.
You don't have to modify the tank, but the bracket that bolts to the frame is different.
Also the internals are different as well as the way they are installed.
The pump mount on the plastic tanks installs on the bottom.
If you are buying a tank with all the internals included it's an easy swap...
otherwise it would be more economical to get another steel tank.
