Ten Kate Honda rider Jonathan Rea has taken his first race win of 2012 in drying conditions during the second superbike race at Assen.
The drying conditions meant tyre choice would be critical, with Rea opting for hard slick tyres, which improved towards the end of the race enabling Rea to push through to the front.
Effenbert Liberty Ducati rider Jakub Smrz took the lead at the start and opened up a gap of over four seconds, but the Czech rider was using intermediate tyres, and his pace dropped significantly in the latter stages of the race, enabling race one winner Sylvain Guintoli and Rea through.
Once Rea made it to first place he was able to comfortably pull away from Guintoli
Smrz though looked like he could still secure third place, but he crashed after running on to the astro turf while trying to pass a back marker.
World champion Carlos Checa made a mistake with his tyre choice, opting for full wets both front and rear. Checa pulled in to the pits at the end of lap three to change to slicks after dropping back to last place. He finished 17th.
Tom Sykes was unable to capitalise on his pole position, the Kawasaki rider struggling with the drying conditions and finishing sixth. Fellow Brit Leon Camier finished 14th.
Chaz Davies was battling for a potential podium finish when he crashed at the second turn on lap 12.
