Le Mans may be known as a Yamaha track, but (factory) Honda riders swept the top four places during Friday morning's first free practice session in France.
Leading a Repsol 1-2-3 was Casey Stoner, with Estoril winner Dani Pedrosa 0.298sec slower and Andrea Dovizioso - still seeking his first podium of the year - 0.675sec from the Australian.
San Carlo Honda Gresini Marco Simoncelli was 0.896sec from Stoner and the final rider within one-second of the top.
Yamaha's reigning world champion, 2011 points leader and Le Mans winner for the past two years, Jorge Lorenzo, was the leading non-RC212V rider with a best lap 1.032sec from Stoner.
Valentino Rossi, due to ride with a new Desmosedici chassis this weekend, was sixth quickest (+1.281sec) with home hero and satellite GP11 rider Randy de Puniet one place behind him.
Rossi's team-mate Nicky Hayden made it three Ducatis in a row, with Monster Yamaha Tech 3 rookie Cal Crutchlow - who impressed with fourth at the recent Estoril test - maintaining momentum with ninth at the end of his first hour of riding at Le Mans.
Directly behind Crutchlow as Lorenzo's factory M1 team-mate Ben Spies and then the second Tech 3 bike of Colin Edwards.
The healing Alvaro Bautista, also due to use a new chassis this weekend, was 14th out of the 17 riders for Rizla Suzuki.
Second practice takes place this afternoon.
