Easy way? The short answer is no.
First, you have to remove the trafficator (turn-signal switch) and stator tube. The stator tube is two (2) pieces on cars (like yours) with an adjustable steering column, so you *may* get by with leaving the lower half in place. The downside is it will be more difficult to get the two (2) tubes put back together__AND THEY ONLY GO ONE (1) WAY__they are slit/indexed to prevent the upper portion from rotating in the lower portion. Many that I've seen have been damaged where they fit together.
Once you've removed the trafficator and wiring (suggest leaving a *pull wire* in the tube, attached to the wires as you pull them out). The aftermarket hub should have a couple of bolts securing it to the splined column There should be a circlip to remove from the splined column, that kept the wheel from sliding too far during normal adjustment range.
Are you sure that you don't want to just polish it up a bit while it's still on the car...?
Alternatively, you could just remove the screws/nuts holding the wheel to the Moto Lita hub, and see if that gets enough access for you.
