Chaz Davies has produced a flawless performance to claim a maiden victory at his Racing Ducati team's home event at Imola and in the process ending Jonathan Rea's dominance.

The Welsh rider got the perfect getaway at lights out and despite coming under initial pressure from Rea over the opening laps kept his composure and a mistake from the defending champion, forcing him wide on lap eight, enabled Davies to escape up the road.

With a useful five second advantage the Ducati rider controlled from the front to record his first win at Imola and halt Rea's dominance. Coming off the back of a double victory at Assen Rea had won the last four races at Imola while Davies had never led a single lap at the Italian track.

Rea's mistake brought Tom Sykes into contention for second place but the Northern Irish rider held off the Yorkshireman to ensure he only conceded five points in the title race to Davies.

Further back Jordi Torres notched up his best result of the year on the Althea BMW in fourth after Davide Giugliano slipped back late on. Despite a late scare Leon Camier saw the MV Agusta home in sixth ahead of Honda's Michael van der Mark while Lorenzo Savadori pinched eighth from Nicky Hayden on the final lap.

Xavi Fores repeated a similar trick to take tenth off of the sole Crescent Pata Yamaha of Alex Lowes, who battled on alone after his team-mate Sylvain Guintoli suffered a heavy high side in qualifying which ruled him out of the race.

Matteo Baiocco, Markus Reiterberger, Josh Brookes and Alex de Angelis completed the points positions.

The initial race start was abandoned after Dominic Schmitter low-sided on the warm-up lap and the unsuspecting Peter Sebesteyen was given nowhere to go and rode into the stricken Swiss rider. Not to miss out on the commotion, de Angelis dropped his IodaRacing Aprilia machine on the grid as the start was red flagged.

After a quick restart, with the race reduced by a lap, Davies produced the perfect getaway from pole to grab the holeshot while his Ducati team-mate Giugliano was swamped by the Kawasaki duo of Rea and Sykes into turn one.

The Welsh rider looked bolt away from the charging Rea and Sykes over the opening laps and as forecast by the free practice pace Rea was able to match Davies with Sykes slightly slipping further back in third.

Rea had been applying increasing pressure over the opening stages but on lap eight ran wide on to the grass and duly lost a huge chunk of time which enabled Davies to escape up front while bringing Sykes right up to his exhaust pipe.

Elsewhere, Savadori began suffering with early tyre wear on his Aprilia and fell back through the pack while the second Racing Ducati bike of Giugliano slipped from fourth to sixth in the space on two laps.

But the star was Davies who controlled his pace over the final laps to take victory with ease and trim the championship points deficit to 40 points from leader Rea.
