Speedo ID

[XF650]

This CEV speedo came in a box of bike bits & I would appreciate if anyone could help ID the bike(s) that it fits.
I assume it's specific for Italian brands, with "Ducspeed Morini" written on the sticker. But even after a lot of time on google, I haven't been able to ID what model(s) of bikes it belongs to.
Any help much appreciated.

Absolutely no useful advice to offer, but those red digital LCD style numbers kinda scream 1980s to me.

No idea, but Moto Morini made a range of V twins in the 80s the 3 1/2 & 500 so I'd bet it was for one of those & Ducspeed sounds like a lame name for an italian bike shop.
