Katana Swingarm angle

[rodneya]

I working on fitting a GSXR swing arm to my frame. Is 12 to 13 degrees a good number for the swing arm angle? I would like to get the geometry and wheel / chain  alignment all sorted out before i do anything else to her.

13 deg is a reasonable number, I'm sure someone will have a Katana they can measure

Don't know what the angle is but rides well , gsxr 11 arm
