progressive rear shock / spring

Post by boulder_adv_rider » Mon Aug 25, 2008 7:51 pm

What constitutes overly impressed? I'd be happy to test ride one over the next two weeks in the crucible. I'll start here in CO with primary objective Mojave Trail. The trip is pretty good at weeding out fluff. Be happy to stop along the way and swap out on the way back...unless I really like it, of course. --- In DSN_KLR650@yahoogroups.com, Doug Pippin wrote:

Anyone... Anyone.... Bueller? Thanks for the feedback on the Cogent, Doug. Does anyone have any personal experience with more than one brand of aftermarket shock? Bang for the buck, nothing beats a new spring on a stock shock with fresh oil and fresh nitrogen charge. But since I ride the KLR like it's a KDX, I'm seriously considering begging for a new shock for Christmas, or Thanksgiving, or any old effin reason... da Vermonster BTW, anyone know the expected life of a shock spring? My 500/560 spring now requires preload at 5, and I don't remember it needing that much when I first got it.
