Noriyuki Haga: "For sure I was unlucky for the first race but I'm very happy for the second place. It was a really tough race with Troy and I was looking for a way I could pass him but I couldn't find one. But I never gave up and tried my best until the last lap. You know, I'm very tired and now I'm looking forward to the next round at Monza, where I won both races last year."

Carlos Checa: "It was quite a bad start as usual for me, we need to improve that area. Of course it was a very hard race, we made some changes and I was not comfortable at the beginning, but I was able to keep a good pace and catch the guys in front of me and finish on the podium, which for us was a surprise because I didn't expect it at the end."

World Supersport

Round 4 of the championship was an exciting affair, with the top 13 riders covered by 3 seconds with five laps to go. Six riders were in with a chance of winning as they started the final lap, but in the end victory went to Andrew Pitt (Hannspree Ten Kate Honda), who edged past his team-mate Jonathan Rea at the final chicane to win by a fraction. A Honda 1-2-3 was completed by Spanish rider Joan Lascorz (Glaner Motocard.com), who consolidated his points lead in the championship. Fourth and fifth place went to the two Yamaha World Supersport machines of Fabien Foret and Broc Parkes ahead of Josh Brookes (Hannspree Stiggy Motosport Honda). Craig Jones managed to place his Parkalgar Racing Honda into the lead for a couple of corners on lap 16 but he slipped back in the final stages to finish ninth.

Superstock 1000

Maxime Berger (Hannspree IDS Ten Kate Honda) scored his first win of the season at Assen. The Frenchman went on to take a deserved win after the race leader Claudio Corti (Yamaha Junior Team) crashed out at the chicane. Second place went to Italian Michele Pirro (Yamaha Lorenzini by Leoni), who was in contention for the win with Corti and Berger, and third to Xavier Simeon (Alstare Suzuki). Winner of the opening round Brendan Roberts (Ducati Xerox Junior Team) capped a difficult weekend when he crashed out in the opening laps.

Superstock 600

The outcome of the Superstock 600 race was virtually decided on the opening lap when a crash eliminated poleman Danilo Petrucci (Yamaha Team Trasimeno). At that point Dan Linfoot was in the lead and the Beowulf Racing Yamaha rider had no problems in taking the chequered flag from Patrick Vostarek (Intermoto Honda) from the Czech Republic and Vincent Lonbois (MTM Racing Suzuki). Valencia winner Loris Baz (Yamaha Junior Team) could only finish fifth.
