Assen was soaking wet for race one and the only wet practice that Troy and rest of the riders did was in the short morning warm-up. The race was one of attrition, with only fifteen riders (out of twenty-eight) finishing. Amongst the casualties were three of the top four in the title chase. Chris Walker (Kawasaki) started from last place, but stormed through the field, mastering the difficult conditions to take his maiden World Superbike win. Second was Andrew Pitt (Kawasaki), with Michel Fabrizio (third). The second race started, with the track virtually dry, but there were a few damp patches around waiting to catch the riders out. After an early battle with Kagayama (Suzuki) Troy Bayliss (Ducati) ran out a comfortable winner with Andrew Pitt second and Fonsi Nieto (Kawasaki) third.

TROY - Race 1: DNF, Race 2: DNF

"What a complete disappointment! Especially after taking Superpole yesterday after a couple of difficult days! The only good news is that I didn’t hurt myself in the crashes. The first race was OK at the start, even though the track was soaking wet and very slippery. I led Bayliss for a couple of laps, but soon my visor started fogging up and I was having to try and look out of the side of it just to see where I was going! I looked up one time and saw I was off line and heading into a large patch of water. Next thing I knew I was down and my race was over.
I hardly got involved in the second race - thanks to Nori. He was next to me off the line and I think he missed a gear and then hit me. I don’t know exactly what happened, but when I tried to brake for the turn, nothing happened. I went down and it was only when I saw the front of my bike that I realised that my front wheel rim was broken and one of the brake discs was damaged. Today the weather ruined everything. If today had been dry, I think I would’ve taken two podiums for sure, but that’s the way it goes sometimes."
