World champion Jonathan Rea claimed a seventh win of the season by just 0.025 seconds to extend his lead at the top of the World Superbikes championship.
Rea started the second race of round four in Assen from ninth on the grid, but made a brilliant start and needed less than three laps to surge into the lead.
The Northern Irishman looked to be cruising to an 11th win at the Dutch circuit in the 200th race of his career, only to run wide on lap 10 and allow Kawasaki team-mate Tom Sykes to close the gap.
Sykes made a last-ditch bid for victory as he powered out of the final corner, but Rea held on for the win to move 64 points ahead of Sykes in the standings.
"Another double, what can I say?" Rea told Eurosport. "I'm so happy.
"The last sector I just had to defend as much as possible and get it to the line. A Kawasaki 1-2 in both races is an incredible weekend for the team and me as well.
" It's so, so hard to lead round here in the wind today; it's so strong I actually lost the front in the fast right, my foot came off and after that my lap times just dropped.
" It was actually quite dangerous in some places. You go past the pit wall and the wind gusts you off the track - it's mental."
Britain's Chaz Davies (Ducati) finished third, with Holland's Michael van der Mark giving the home fans something to cheer in fourth.
Britain's Alex Lowes and Leon Camier were fifth and sixth respectively, with Ireland's Eugene Laverty dropping back to eighth after leading in the early stages.
