The Yamaha's chassis made me feel awkward, though it was very stable. The rougher the track was, the better the suspension worked. I was aggressive with the motor because it is smooth. I did feel the motor was a little slow, however. I liked the way the Yamaha turned on flat-track-style corners. The rear brake worked a little too well, making it difficult to drag. Overall, I felt uncomfortable on the Yamaha but the suspension made it a fun bike to ride.
Being tall, I found the KTM roomy. The motor was very impressive and not far off the Honda's. The hydraulic clutch worked very well. I felt the suspension was plush but too soft; it caused the bike to dive under braking and bottom on jumps. Sometimes the front would knife when trying to turn under another rider. On acceleration bumps, the rear shock would not track straight. With a few adjustments, the KTM could be at the top of my list.
