Rea was second quickest, despite suffering a late technical issue. The hour long first qualifying session at Assen was halted for a few minutes to clean up an oil spill, leaving only one last flying lap for the riders to improve their early qualifying pace.
The official BMW Motorrad Motorsport S1000RR of Troy Corser was third quickest at the end of day one, proving that the BMW team has made a repeatable jump in its real world abilities, following the team's best ever fourth place finish at Valencia last time out.
Corser was 0.4 from provisional pole man Smrz, on this 4.542km track, which features a faster Ruskenhoek chicane section than last year.
Championship leader Leon Haslam (Suzuki Alstare) rounded out the early top four at the 4.542km circuit, proving his prowess once again at another different layout and character of circuit.
Cal Crutchlow (Sterilgarda Yamaha) crashed more than once in the first session but still went into the top five, making it five different types of machine in the top handful of spots again.
Sixth was the early result for privateer rider Carlos Checa (Althea Ducati) and Leon Camier (Aprilia Alitalia) outqualified his team-mate Max Biaggi today, going seventh to Biaggi's 16th.
Chris Vermeulen's comeback ride put him 20th on the opening day for the official Kawasaki Racing Team, but his team-mate Tom Sykes was top ZX-10R rider, 12th from the 22 riders.
Jakub Smrz: 'I have a very good feeling with this track and every time I come back it is very satisfying to ride here. I like the new section but I do not have the gearing correct yet for that part, so there is more to come. I am ready for the rest of the weekend and I hope I will be battling for the top positions, especially at this track.'
Jonathan Rea: 'We did a nice race run this morning and also went through a few tyres to find the best choices for the race, and I think we will try the best combination of front and rear tomorrow. I am really enjoying riding and in a rhythm now. I do not have to ride on the edge to achieve a lap time. We have more grip on the rear after our test here and we still managed to keep a good front end feeling.'
Troy Corser: 'The team has done a great job and the traction control is working very well. The bike feels very connected. Both throttle and engine braking systems have given me a good feeling and our engine is pushing strongly. From first to fifth gear the acceleration is really hard. Overall, the bike is a good package now. Unfortunately, someone crashed in the last chicane when I was on my flying lap at the end of qualifying, and I lost another chance to go faster.'
