I took Sniper's 919 for a spin. His has 04 forks and an Ohlins rear shock. There was much less jack hammer effect on his than mine, but I don't hit the roads hard enough to justify spending nearly $1,000 for a rear shock. I would like to get adjustable forks and the correct rated springs for the front.
I say I don't hit the roads that hard, but I hit them hard enough that the sides of my tires are more worn than the center. I'll most likely hit the side wear bars first.
EDIT: So to answer your question, put the proper RaceTech springs in the front and adjust the rear as close as possible. This will get you close enough unless you are pushing it really hard on the street or track. I've put 10,000 miles of twisties on my 919 with no suspension mods and it still keeps up with the sportbike crowds.
