I weigh 280, and I got my suspension done by MXTECH. They did a verry good job, they had all the springs. I would check them:thumbsup:

Hey Tim,


Satch has the right Idea...the race tech website will allow you to input your riding style and weight(w/o gear) and give you their recommended specs. Once you have the correct spring rates, you can then play with Fluid viscosity, fluid height, and clicker settings, and Race Sag... The info that Satch provided is avail at:

Shock Spring:
