The Katoom is definetly a stand-up riding bike. The riding position is extremely forward which is great for tight woods work. The feel that I've always gotten when riding them is a steep rake that allows quick flat direction changes between trees, but can feel odd at first when sitting down.
Now when I get back on some other bikes, they almost feel throwback-low in the rear with swept back bars and rearward seating position.
Suspension set-up, particularly race sag, critical for these bikes to work well (as most bikes), it just seems the KTM is a little more sensitive.
