My 6500 came with stock Manitou 6's on it.
I've only had the bike about 2 months at which time I think I've ridden it less than 3 times. The fork is now leaking fluid at the rebound adjuster.
I am going to take it in tonight to see about warrenty! Hopefully can get an upgrade or something. I think that the stock 6's are too soft for me!
