Hi Scotto,
I used to have a 02 KTM 400 EXC and found that the MSC Damper fixed the problem instantly, you can push your bike harder and with more confidence. I raced enduro for a few years and it saved my arse many times.They are expensive but consider what could happen otherwise.
I actually bought my forks up through the clamps approx 10mm and it still handled well at speed and the steering became more responsive in slower trails, like what you prefer, ie steers quicker.
Hope this helps mate.
Cheers Marty
