The Moto3™ FP3 outing on Saturday at Montmelo saw Estrella Galicia 0,0's Alex Rins top the timesheet with a 1'51.450 lap, with Red Bull KTM Ajo's Luis Salom and Rins’ teammate Alex Marquez just behind him.
Rins’ time was the fastest lap ever recorded by a Moto3 bike around the Circuit de Catalunya.
Also featuring towards the business end of the timesheet were Mahindra Racing's Efren Vazquez, Caretta Technology - RTG's Jack Miller and GO&FUN Gresini Moto3's Niccolo Antonelli - all within the top six.
A low speed high side for Miller saw him thrown over his handlebars, but he was soon back out on track to register the fifth fastest time of the session.
Marc VDS Racing Team's Livio Loi, San Carlo Team Italia's Romano Fenati, Mahindra Racing's Miguel Oliveira and Team Calvo's championship leader Maverick Viñales completed the top ten.
Qualifying for the Moto3™ class at the Circuit de Catalunya takes from 12.35pm-1.15pm local time this afternoon.
