I always put a zip tie on one of my fork legs to gage how much of the available travel I'm using when I'm evaluating my suspension. No matter what valving, spring rate, or oil height I use in my W/P forks, I always have about 1 1/2" left at the bottom of the stroke. I have a 2001 400 EXC with SXS internals, a 2001 300 EXC with stock internals, and a 2001 YZ 250 F - stock. We ride in an area with very deep whoops, and verticle hills with "V" bottoms, so I know I'm using the travel. I would tell you I favor a fairly "plush" setup. MY YZ (and my buddies CR's and YZ's) always finish up with around 1/2" left showing at the end of the day. The KTM evidently has a very agressive anti bottom system, you can feel it when collapsing your forks the last couple of inches when setting the oil height. It would be nice to use the other inch of the available travel. Any solutions? (Example: 300 EXC, 5 wt. oil, 140mm oil height, .42 springs, stock valving, stock preload - Senior "A" rider) It is the same on my buddies KTM as well.
