With the Kayaba PSF fork being introduced to motocross on the 2013 Kawasaki KX450F and Honda CRF450R, there seems to be a lot of confusion, misinformation, and rumors regarding proper setup and adjustment. We cornered Dan Worley, owner of SDi, to set the record straight. Why did we choose Dan? Because he's a former KYB suspension technician and helped develop the fork in question...that's why.
