2015 KTM 450SXFE

Posted by

We have had a month or so on the new 2015 450SXFE. We have gotten a lot of questions about spring rates and settings and of course general impressions.

Here are the bullet points.

  • Awesome light feeling / neutral handling.

New Shock is really interesting.

  • 12mm Shims.
  • New MX-TECH low friction piston ring required.
  • New Shock piston design, simliar to PDS piston.
  • New motion Ratio, much higher shaft speeds.
  • Shorter Shock Spring.

New Updated 4CS fork.

  • Air spring is 100% bottoming control. (Dummy hardware no-cup supplied.)
  • Longer fork rods. (Must use updated 4cs asymmetrical system, with shorter bottoming cup.)

I’ve come up with a nice Chart that shows the correct springs for the rider.
