huge difference

put the progressive fork springs in as well.. did the 444 shocks and suddenly my bike was hugging the road on those tight bends... ripping round those long sweepers with out flinging me onto the other side of the road.. I am now carting the missus around with me again and the bike doesn't leap off the road when I hit pot holes or bottom out any more.. though after 3300 kilometres last week with my mates I find that I will have to adjust them again as they have gone a little soft so today I wash bike and readjust shocks and we see how they go next week.... the instructions said they may take a little time to bed in...

Progressive 444 HD shocks

Definitely better than stock. No more wallowing in the turns and takes the bumps much better. Our roads suck out here, nothing like the nice smooth roads heading to Sturgis or 4 Corners Rally's. Easy install.
