Alex Debon emerged at the head of the Moto2 timesheets during Friday free practice for the second round of the newly formed World Championship, at Jerez in Spain.
The home rider - second at the Qatar season opener - put his FTR motorcycle on top by a lengthy 0.461s at the end of the hour, with former 125cc world champion Gabor Talmacsi proving to be his nearest rival. Talmacsi's Speed-Up chassis is also based on the FTR design.
Third fastest was grand prix rookie Kenny Noyes, who returned to his impressive pre-season testing form at a circuit he knows from Spanish Superbike racing, while Yuki Takahashi was fourth for Tech 3.
The chassis variety continued with Sergio Gadea in fifth for Pons-Kalex, followed by wild-riding Columbian Yonny Hernandez, who 'backed' his Blusens BQR to the top with 15mins to go before slipping to sixth.
Reigning 125cc world champion Julian Simon was seventh for the Aspar (RSV) team, with testing pace-setter Claudio Corti the top Suter rider in eighth.
Swiss Thomas Luthi led the Moriwaki challenge in ninth while Frenchman Jules Cluzel, third at Qatar, began the weekend in tenth for Forward Racing (Suter).
Despite Debon's advantage, the top ten was covered by just 0.9s and the top 17 by less than 1.5s.
Toni Elias, pole and fourth in Qatar despite fresh hand and foot fractures, began his home round with 13th for Gresini Racing (Moriwaki) while Shoya Tomizawa, a surprise winner of the inaugural Moto2 race at Qatar, was 14th for the Technomag-CIP (Suter) team.
