A short, fat guy, a couple of Hagons and a Rocket Touring...

The dealer that ordered your shocks should have had them made for your wieght and to go on the rocket. I can't think how that would not happen.
 
All Rockets use the same shock. If you ordered form Hagon they should ahve came with the correct weight spring and prload set close to where it needed to be. Either you got the wrong spring rate or the install removed all teh preload.
 
Hard to see the diff in weight.
Even if 50 pounds, its not all over the shock and should be "built" in to the shock model/design.
I have heard all good with Hagon.


 
Well, I'm around 240lbs, & have the Hagon nitros at 340mm ( extra long) If anything, the springs are too hard!! certainly no chance of bottoming.
