Yamaha's two MotoGP rookies endured a forgettable Malaysian Grand Prix at Sepang on Sunday, each falling in separate accidents by lap 12 of 21.
Satellite Tech 3 rider Toseland was the first to exit, the double World Superbike champion had been bumped from 12th on the grid to 16th during the opening lap melee and was trying to fight his way back up the order when he asked too much of his front tyre on lap 3.
"Qualifying 12th though makes it tough, especially here and I got boxed in a bit at the first corner," recalled Toseland. "I braked after everybody else and made a couple of places up but ran wide and then it was a real dogfight. I was having a close battle with de Puniet and West but then when I picked up my pace I went down.
"I had to run a harder front tyre to make the race distance and I think it just needed another lap to get the temperature in it. I just pushed it too hard and lost the front at turn six. I paid for pushing too hard trying to make up the time I'd lost. I was confident after [warm-up] when I was eighth and we'd make progress with the bike, so it is a bit disappointing. But I'll be going all out to make amends in Valencia and finish on a high."
"James didn't get the start he wanted and he was pushing hard and crashed. But if you don't try then you only follow everybody, so while it was a disappointing for him, at least he was fighting," said team manager Herve Poncharal.
Lorenzo had qualified his Michelin-shod M1 third on the grid, but got another disastrous start left the Spaniard just eighth through the first sequence of corners. The Estoril winner had just taken sixth position from Shinya Nakano when he lost the front of his M1 through the tight first turn on lap 12 (pictured).
"I didn't feel good today and I was riding much worse than yesterday," he admitted. "I was having some problems in braking and acceleration and this is really a pity because I thought I had the chance to be on the podium.
"I had many problems with my tyres in the first few laps and in fact I had a lot of warnings about the crash, but in the end I just couldn't avoid it. I got a bad start and it seems this part of the race is getting more difficult every time. If I had a better start I could have tried to go with Valentino and Pedrosa but today was terrible. We have to change something here because at the moment it's quite difficult.
"Apart from these problems I know I didn't have the same feeling in myself as I had yesterday, so it really wasn't a good day! It's a little sad now that we can only be fourth in the championship, but I can still be rookie of the year so I will focus on this because it's important for all of my team," he added.
Lorenzo leads the Rookie of the Year standings by 21 points over Andrea Dovizioso heading into next weekend's Valencia season finale.
