Suspension set-up KTM 300 EXC '03

It sounds to me like Pro-action didn't valve it to meet your needs. In my experience, the only way to get plush action on rocks and roots is with good valving. I would call Pro-action, tell them your problem, and ask them to fix it for free. You also have to do a good job of telling them how you ride and where you want the suspension to work the best. In my experience, I have never found a KTM since they went with WP components that was as versatile (plush AND controlled) as the older Ohlins/Marz combo or Yamaha suspension, but a good valving can get it close.

Correct on the above statement. A reputable suspension shop should be able to deliver what you ask to you satisfaction. Give them a call and see what they can do. It might be a pain in the rear shipping back and forth but you should get what you pay for.
