I have Progressives on my Bandit, and Progressives and the gold emulators (got brain lock, cant' remember the name!)which was a bit overkill..on my Harley Softail Deuce, which is not know for handling..
but the handling on both bikes was vastly improved...
the Bandit stopped nosediving, it was kinda like a stock SM, and now the Harley rides like a truck, but it literally stays glued to the road... the Metzler's helped too....
The SM is next...when I get my other bills paid up!

(
I'll put progressive rear shocks on too....
