900ss battery

[lozz900]

Hi all..
My 89-90 900ss ducati wont fit the recommended motobatt MB16AU battery. My maximum footprint size is 205 x 70mm which is a bees dick smaller than the motobatt...
What do you people on here reccomend as the minimum CCAs I could get away with on a 2V belt 900 ducati?

Katana YB16AL-A2 is 5mm smaller than everything else and fits ..
Its lead acid but it's better than nothing..
