Alvaro Bautista will try and secure only his second victory of the 2008 season from pole position at Assen on Saturday, after a final qualifying session in which the top two riders failed to improve.
Bautista will line-up 0.231secs ahead of countryman Hector Barbera, with Marco Simoncelli - whom Bautista has tangled with during several last lap battles, most recently at
Donington Park - improving his time but staying in third.
Alex Debon completes the front row, while Donington winner and world championship leader Mika Kallio will start just eleventh after being bumped down a position.
Simoncelli, Debon and Roberto Locatelli (ninth) were the only riders in the top ten to lap faster on Friday.
