Dunno about the EV BUT Daytona/Sporti et all the speedo looks very similar
As already pointed out Tach is electronic
Mounting points look about right for Sporti/Daytona too
I'd check wheel diameters and ratios before jumping.
Funny I found myself in a similar position and was looking to get rid of the hideous blue speedo on the Sport, but now I'm waiting for a Harley gauge mount from Flea Bay that I won to see if a little experiment and modification might work.
If it does gauges will either be SpeedHut or Marshall, I prefer the Marshall but the SpeedHut gauges offer better mounting, more flexibility, and can incorporate some warning lights too
I'll post on it later if it looks like a goer
