Just received this from china:
It's a voltage meter, nice sized and I'm sure you guys with the front fairing on could find somewhere to mount one also.
I'm realy impressed with the quality of it as I baught it from china for about £3.20 deliverd!
Koso are selling similar for £39.95
Only one down side is it doesn't have a back to it
So guys on nakeds would need to make a back case or fill it with some sort of silicon.
Works on anything from 7v to 30v
