There appears to be a new rule of thumb for gauging the weather: If there’s a motorcycle race on, then chances are it will be raining, at least for some of the time. After a weekend of climate-curtailed practice 7 days ago at Jerez, the weather looks like being a major factor at Estoril as well. Though no rain fell during any of the nine sessions of practice – two Moto3, two Moto2, two MotoGP and three Red Bull Rookies – took place, the rain was still very much a factor. The day started with a wet Moto3 session, the track taking a long time to dry out after the overnight rain that lashed the circuit. The track started to dry during MotoGP FP1, and by the second half of that session, it was dry enough for everyone to run slicks, albeit the softer compound that Bridgestone has brought.
By Moto2 FP1, the track was nominally dry, but problems with the damp remained. Parts of the track have been resurfaced, in particular, Turn 6 and Turn 13, and though the new surface is pretty good in general, the problem is that the new asphalt is still dark, and it is impossible to see where the damp patches are. At Turn 13, the sweeping Parabolica that leads back onto the front straight, the problem is exacerbated by the fact that water appears to be seeping up through the ground, which is still saturated after weeks of heavy rain.
As a result, though the afternoon sessions all looked to be perfectly dry, in fact there was still a lot of water in the final corner. Worse still, the water was invisible to the naked eye – or at least the naked eye travelling at upwards of 100 mph aboard a racing motorcycle. Consequently, everyone was taking it easy through that final corner, and losing out massively in terms of lap times. Monster Tech 3 Yamaha estimated that most riders were losing about 1.5 seconds in that part of the track, not just in terms of corner speed, but also due to losing the drive on to the front straight.
Top speeds for the 1000cc MotoGP class are only a couple of km/h faster than in 2011, when the bikes were still 800cc, and had 30-40 hp less. At a track with a reasonably fast final corner followed by a kilometer-long straight, the 1000’s should be slaughtering the top speeds set by the 800s. The MotoGP bikes are four tenths down in the third sector, and nearly half a second slower in the final sector, including the final turn and run on to the front straight. All that means that lap times are seriously down on where they were last year, in all classes.
