Rack for Topbox

[SFC1000]

I have a Honda top box fitted to the bike and I removed the top box to clean the area underneath it.
The plastic plate that the top box connects to moves approx 5mm from side to side.
The plate does not just move from side to side but is 'springy' like it  is supposed to be like it. 
There is no back and forward movement.
I have removed the 4 x fixings and it would appear that the only way to remove this sideways play would be to install some thicker washers.
I do know that Triumph build in movement to their panniers allowing them to move and is this a similar thing?

That's normal.  I've just checked and it's the same on mine.

Thank you.

Yes, it's normal and is there to damp out the effect of anything in the top box moving sideways which could unsettle the bike in a corner if it was something heavy.

Yes I have noticed the very same thing on Wednesday past, great to hear this is a built in feature. :)
