As always, Bridgestone issued a post-race press release debrief with a senior representative. Today it was the turn of Shinji Aoki, head of the Japanese tire manufacturer's motorcycle tire development department. Aoki discusses the challenges faced by racing on a drying track, the purpose (or otherwise) of scrubbing in new wet tires, and the fact that the harder of the two compounds Bridgestone brought to the circuit went unused.

Last weekend’s Dutch TT at Assen was affected by variable weather conditions that resulted in the race being a flag-to-flag affair at which Repsol Honda’s Marc Marquez won ahead of Ducati’s Andrea Dovizioso and Dani Pedrosa on the other Repsol Honda RC213V.
With the win at Assen, Marc Marquez brought his tally for the season up to eight, and a clean sweep of the races so far. After the race, many fans remarked on Marquez' remarkable pit swap strategy, jumping straight from one bike to the other without touching the ground, rather than hopping off one and onto the second bike, as the other riders on the grid do. It looks spectacular in photos, such as this one tweeted by Marquez himself, though if you watch the video from MotoGP's Youtube channel, it's clearly more of a hop than a leap.
Did Marquez get any benefit from it? The best way to answer that is to measure it, and fortunately, the MotoGP.com website offers us two ways to do that. The results section of the website holds a PDF with an analysis of every lap done by each rider, broken down into sector times. By taking the times posted by each rider for the last sector of the lap on which they entered the pits, and the first sector of the lap on which they exited the pits, we get a clear idea of how much time riders lost in swapping bikes. In addition, the video of the race on the MotoGP.com website (MotoGP.com subscription required) shows on screen the times riders actually spent in the pits, from crossing the pit lane entrance line to the pit lane exit line. Using these two numbers, we can get a fair idea of who comes out best after making their pit stops.
2014 Assen Post-Race Round Up - Of Tire Gambles, The Wisdom Of Thinking For Yourself, And Lorenzo's Fear
A veritable galaxy of stars may have lined up on the grid for the 84th Dutch TT at Assen, but the real stars of the show were the elements. After the rain wreaked havoc on qualifying, shaking up the grid, it was back on Saturday for two of the three races. Riders and teams were forced to rethink their strategy, make decisions quickly, and gamble on tires and the weather. It made for intriguing races, rather than sheer thrills like the MotoGP race at Barcelona. Changing conditions offered the brave and the smart opportunities, and mercilessly punished anyone who got it wrong. You felt for the 45 minutes of the races that anything could happen.
The Moto3 riders had it easiest of all, conditions cool but relatively consistent. The track did not allow for mistakes, however: Jack Miller's strategy of trying to pull a gap early backfired badly, the Australian crashing out of the lead. Miller's saving grace was that Romano Fenati, his main rival in the title chase, made even bigger mistakes than he did, crashing out twice, and failing to score points. The day belonged to the Hondas, with Alex Marquez controlling the race from the front, despite challenges from teammate Alex Rins and a quickly closing Miguel Oliveira. With two Hondas and a Mahindra on the podium, this was the first time since Le Mans 2012 that a KTM was not on the podium, and the first ever Moto3 race where a KTM engine did not power any of the podium bikes.
Conditions were much trickier for the Moto2 riders, rain falling heavily before the race, but then quickly starting to dry. It was clear that if the rain held off, a dry line would soon appear, and a few riders gambled on fitting a slick rear. The rain did not hold off, however, falling heavily again in the early laps. That put riders like Dominique Aegerter, who had reckoned on using a slick rear, a long way behind the leaders, his tire only coming good in the second half of the race. The rain allowed Simone Corsi and Sam Lowes to get away at the front, pulling a big lead in a short period. The pair looked set to dispute victory between the two of them, but Lowes pushed a little too hard, losing the front and going down. Corsi could have just cruised to victory, but that proved too much to ask, the NGM Forward rider crashing out of a commanding lead at the halfway mark.

Success in motorcycle racing is a fickle beast. Getting everything just right to get the best out the bike and rider is a difficult undertaking, with a thousand factors standing ready to throw a spanner in the works. The bike has to have the right balance of stability in braking, nimbleness in corner entry, and strength in acceleration. The rider has to be in peak physical condition, mentally on top of his game, and ready to seize any opportunity which presents itself. When track conditions are ideal, the rider has to be able to find the limit of adhesion. When track conditions or the weather are not playing ball, the rider has to guess the right time to attack, and the right time to hold off. They have to judge how the conditions are changing and when they are ripe to be exploited. Get it right, and you dominate. Get it wrong, and you are lost in the pack.
You also have to be lucky, or know how to make your own luck. The qualifying session for the MotoGP class at Assen showed just how big a role luck can play, the weather playing a massive role in proceedings. The weather changes fast at Assen. In a country as flat as the Netherlands, the wind blows cloud and rain in quickly, and carries it away just as fast. Bright sunshine can change to heavy cloud in a few minutes, with rain following on behind. Which is just what happened on Friday afternoon. Sunshine made way for gray skies, the air pregnant with moisture. It spotted with rain in the morning, briefly during FP4, but only really struck during Q2. It threw the plans and running order of MotoGP into disarray, with smart and lucky riders winning out, the ill-starred ending up well down the grid.
The weather demonstrated how sometimes, disarray can turn to your advantage. Skies had been getting heavier all throughout Q1, though it was never more than a few drops which fell. That changed as Q2 got underway. Rain started falling more heavily at De Bult, the mid-section of the southern part of the circuit, just as Q2 got underway. That caused a sprint race from pit lane exit, the riders battling more like a bunch of Red Bull Rookies than experienced veterans of motorcycle racing's premier class. The sprint soon turned into jockeying for position: nobody wanted to lead, as being the first rider into a corner turned you into the guinea pig, testing grip for everyone following. Following was not much better: though you could at least see what the conditions were for the riders ahead, you did not want to get stuck in the traffic behind. Eleven riders left the pits together, getting stuck watching each other, speeding up, slowing down, and constantly trying to figure out what the best strategy might be.
