Good Question - I have the rear mono shock assembly in a box somewhere - Been a while since looked at -Has anyone thought about using a gold wing air ride compressor for this mod? It seems like it would be perfect for this application.
But It appears to be hydraulic -
It is a motor with an hydraulic hose from it to the shock.

This guy knows how we like stuff displayed.
I was sure the small unit was a worm drive assembly
Quick Search - poor image quality - New - $1000.00 assembly. 01 - 05 years
Ebay - PART # 52400-MCA-003
What's kinda weird - look what a Goldwing looks like with bags stripped off-
Who'd a thought it's almost built like a car - http://www.pbase.com/fredharmon/image/20370752
