XS250 / XS360 / XS400 fuel tank

[Alex_D]

Im looking to change the tank on my XS400 to the older "square" or "boxier" tank
And I've maybe found one in decent shape from a XS250.

Is it the same as the other ones? Will it fit bolt-on on the 400?

I know the earlier XS400 had the boxy tank. I doubt the XS250 tank will bolt right on. You'll most likely have to modify the mounts.
