With all the usual disclaimers that I do not know what I am talking about so cannot assume responsibility for damage....
There is. Especially if it is 5km across the dial. But it takes dismantling glass and removing the hand. If you are fluent in such work, you can do it. If not, better give it to a professional.
Remove the glass. (I fabricated puller for this)
Raise the tip of the hand gently and guide it pass the stop peg.
Place speedo vertically and let the hand rest under its own weight. Mark the position of the hand on speedo housing.
Remove the hand.
Re-attach it 5km/h earlier than it was.
There are videos on youtube about it:https://www.youtube.com/watch?v=6KgTtRFFuvQ
