Repsol Honda could regret its decision to sit out the Aragon test come September's race weekend, if Jorge Lorenzo's comments about set-up prove tru💦e for the RC213V riders.

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

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

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

The counter argument from HRC will surely be that working on se♍t-up without the tyre spec available for the race is of limited value.

But Yamaha also ha🐠d new components test and while the revised electronics 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 ha💎ve to make a decision for moving forward," sad Lorenzo, who holds a 20-point lead over reigning champion Stoner afteꦛr five rounds.

"They will consider the da﷽ta from today t🔜o help them."

Lorenzo's bes𝐆t 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 majority of the day, the test marked a further chance to rebui🧜ld his confidence after a tough start to the year.

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

"We've worked really well with the bike and the electr♉onics 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 followed on the timesheets by sat✤ellite riders Cal Crutchlow and Andrea Dovizioso.

The Aragon race weekend, round 14 ൩of the 2012 season, will take pla𓆉ce from September 28-30.

Lorenzo and Spies꧑ will be back in action along their MotoGP rivals during the British Grand Prix at Silverstone next weekend.

The new spec front, already popular with the Yamaha rider✱s, will become standard from Silverstone.
