  I hope you understand that by just stiffening your front end you may get 
 unwanted results. This will greatly change the frontend performance. To
 really do it correctly the springs should be custom built to you weight
 and type of riding that you do most. (I hate harsh front ends that wash through
 corners and wipe out my wrists on rough terrain. My personal favorite spring
 is a progresive (alot less expensive, and yes a compromise to custom dynoed
 springs. The give the plush ride when my body needs it but the performance
 when I ask for it. My riding is everything but moto so this is where my 
 experience come from.
  I hope this helps. I have palyed with bikes for years. I hope too hold up
 for many more.
