Repsol🧸 Honda could regret its decision to sit out the Aragon test come September's ra🌃ce weekend, if Jorge Lorenzo's comments about set-up prove true for the RC213V riders.

Casey Stoner and Da🍷ni Pedrosa were the two main absentees from Wednesday's test, which followed a post-race outing at Catalunya on Monday, due to the new-spec front tyre not being made available a൩t Aragon.

MotoGP Wor♋ld Championship leader Lorenzo led an all-Yamaha top four at the Aragon test, as he put further mileage on a new engine and electronics package, but also claimed it hadn't been easy to dial-in the 1000cc bike.

"Thi🍌s test has been very important because it's not easy to find the best set-up for the 1000cc bike here as there is so much change from the 800," said Lorenzo, who finished 0.255s ahead of Ben Spies.

The ℱcounter argument from HRC will surely be that working on set-up without the tyre spec availab🍰le for the race is of limited value.

But Yamaha also had new components te♈st and while the revised electronic♏s seem popular, the engine is less clear cut.

"We tried the engine again like we did in Barcelona, there wasn't so much difference so the 🦩engineers now have to make a decision for moving forward," sad Lorenzo, who holds a 20-point lead over reigning💜 champion Stoner after five rounds.

"They will consider the data from t🍬oday to help them."

Lorenz♚o's best lap, of 1m 49.187s, was just a fraction꧂ outside the official lap record set by Stoner in last year's race.

For Spies, who led the ma🙈jority of the day, the te🌃st marked a further chance to rebuild his confidence after a tough start to the year.

"Today was a good test, to come back after not suꩲch a fantastic race on Sunday and be consistently fast here and in the Catalunya test is important," said the Texan.

"We've worked really well with the bike and the💃 electronics and just tried to change a few things and fine tune.

"The track was a lot better than we thought, we were expecting it to be quite dirty but it wasn't. I feel like I'm getting back up to the potential of the bike and myself which is good."

The Factory team-mates were foll𓆏oꩲwed on the timesheets by satellite riders Cal Crutchlow and Andrea Dovizioso.

The Aragon race꧙ weekend, round 14 of the 2012 season, will take place from 🌼September 28-30.

Lorenzo and Spies will be ♕back in acﷺtion along their MotoGP rivals during the British Grand Prix at Silverstone next weekend.

The new spec front, already popular with the Yamaha riders, will become ꦑstandar▨d from Silverstone.
