Bancaja Aspar's Nico Terol kicked off the 80th Dutch TT at Assen by topping the timesheets in first session of free practice for the 125cc class. Terol took over the top position from Tuenti Derbi's Pol Esparagaro, who had led for most of the session, but eventually had to let both Terol and Red Bull Ajo's Marc Marquez ahead of them. Terol's Bancaja Aspar teammate Bradley Smith rounded out the top four, and was the last rider within a second of Terol.
The changes to the Ruskenhoek corner - widening the entry, and turning it from nearly a right angle corner to a diagonal corner - have made the track considerably quicker. Though nominally only 10 meters shorter, times were 3.5 seconds quicker than the same session last year, and over 2.2 seconds quicker than Sandro Cortese's 125cc pole time from 2009.
