Nico Terol's bid to go one better in 2011 and win the 125GP World Championship got off to a good start during testing at Valencia as he claimed the fastest at the end of the opening day alongside Sandro Cortese.
The pair shared the top spot on the 'unofficial' timesheets after both being credited with a best lap of 1min 41.0secs.
While Terol is tipped as a title contender this season after finishing second to Marc Marquez in 2010, German racer Cortese suggested he will be a reckoned force too as he posted some impressive times on the Racing Team Germany Honda.
Perhaps the biggest surprise of the test was rookie rider Maverick Vinales, who was just two tenths slower than the leaders and quicker than more experienced team-mate Sergio Gadea. The pair enter this year aboard the distinctive Paris Hilton-endorsed PEV Aprilia.
Miguel Oliveira – second to Vinales in the Spanish championship last year – posted an identical time of 1min 41.8secs to place him ahead of Hector Faubel and Alberto Moncayo. Next up, Johan Zarco led a quartet of Ajo Derbi's ahead of Danny Kent, Efren Vazquez and Jonas Folger.
Elsewhere, ambitious Indian company Mahindra made its track debut with Marcel Schrotter and Danny Webb, the pair 3.8secs and 4.6secs off the pace respectively.
