Hey Guys, thanks for having me to the group.  Looking forward to getting some good info.  I just want to start off by saying that I'm loving the bike, been real good to me this past year.  My issue is with the rear suspension.  Even with just myself on the bike, I find the rear suspension weak.  I've got the coils turned to max but I bottom out over pretty much every obstacle in the road.  I find the suspension squatting quite a bit when it shouldnt.  I'm not an overly heavy guy.  I've had to fab my own metal skid plate since the factory broke. Now i wasnt expecting much from a plastic skid plate but I wasnt expecting the rear suspension to squat so much either.  Anyone here that can point me in the the direction of some good aftermarket rear struts that are stiffer?

Welcome to the group. Yeah the 400 has a lighter load capacity then others but with a shock change...or spring change that can be nicely increased. Might want to pull one, get some measurements and have a talk with our friends at Bandit Suspension.
