Hi everybody!
This time I need an help...and will not be so easy!

I've to reproduce a sticker made between 1989 and 1992 for the Honda Africa Twin that participated at the the competition Paris - Dakar.
The only photography I found on the web is this (as you can see the resolution is not so high...):

Can you suggest from which font I can start? I've really no idea!
Thank you in advance!
