I got given the center stand on the right when I bought my Z1a but not sure if it is actually for the bike ?
The center stand on the left is off a Z1000a2
one on the right is about 1" shorter and the gusset to the foot piece is made from 2 pieces.
Does anyone know (or can check theirs) if the stand on the right is the original for Z1a or off another Z ?
Really only want to send one of them to powder coaters.
Thanks

Mine on my Z1 285mm from ground to centre of bolts , 50mm from ground to bottom of lever hope this helps

Looks like the larger one from the Z1000 is also correct for the Z1.
No idea what Z the smaller one is for ?
Thank you for your time
