The Hayabusa is a Suzuki.  :-)

These days most vehicles use electronic meters because the electronics 
are less expensive and more reliable than mechanical.

If one wishes a simple indicator then R/C servos would be a good 
choice. "Real" meters are expensive!

As nothing but an indicator one doesn't need any holding torque other 
than existing internal friction. As for power and current consumption 
once one has the desired indication then simply quit driving the servo. 
It will stay put.
