Toni Elias made a perfectly timed last lap move on Simone Sanna to win the 125cc Czech Grand Prix, while Sanna crashed spectacularly out of second after trying to regain the lead sending the pursuing pack in all directions.
The result, together with championship leader Manuel Poggiali crashing out, means that 18 year old Elias has now taken the World Championship lead by 22 points.
The 125cc stars completed their parade lap and lined up on the Brno grid with the front row consisting of Toni Elias
on pole, ahead of Youichi Ui, Lucio Cecchinello and Simone Sanna.
As the lights went out and the field charged into the first right hand turn it was Ui and Elias who drag raced into the first turn – with Ui eventually toughing it out to lead around the first turn, with Sanna and local hero Jaroslav Hules behind the top two.
Meanwhile world championship leader Manuel Poggiali was way back in twelfth by the end of lap one, having started only eleventh, with Ueda also down the order in fourteenth.
Back up front 18-year-old Elias was beginning to build a lead over new second place man Sanna, ahead of Ui, Steve Jenkner, Cecchinello and Hules, who was starting to slip back.
Lap three of nineteen and Sanna – victor at the Sachsenring – was continuing to reel in the Telefonica rider up front, while Jenkner was putting Ui under intense pressure for third.
Two laps later and Ui had recovered the ground lost to Sanna and was close enough to overtake Sanna into the first turn – and was immediately on the tail of Elias. However, such was the slipstreaming effect that Sanna was soon back into second, despite the Derbi's apparently superior horsepower, while behind Ui, Cecchinello had despatched Jenkner out of fourth.
The Cat-and-Mouse continued until lap eight when Ui slipstreamed up to – then cut inside - Elias to take the lead from the Spaniard for the first time in the Grand Prix, with Cecchinello now third ahead of Sanna.
