Rear wheel cover on the GP19 and carbon swingarm.
David Emmett: The full set of rear aerodynamics on the Ducati Desmosedici GP19, from the swingarm spoiler to the rear wheel covers. The rear wheel cover mounting points are clearly visible: at the rear of the chain tensioner, and at the front below the aluminum bracket with holes. The rear swingarm spoiler caused huge controversy at the start of the year, and now all manufacturers bar KTM have one.
Ducati used a loophole in the regulations to use the swingarm spoiler and wheel covers, but this loophole will be closed for 2020. For next season, all parts which are not part of the structural part of the motorcycle will be classified as part of the aero body, and so their designs will have to be homologated, with one update allowed during the season. So Ducati can start the season with one spoiler, and alter it once during the year.
Lighter front mudguard on the KTM RC16.
Peter Bom: Although it is a little bit difficult to see in this photo, the mudguard ends immediately after the double L of Bull. This leaves more of the front tire exposed, helping it to run a little cooler and prevent overheating. Some KTM riders have complained of this previously.
The nose section of the Ducati fairing
Peter Bom: This is a great view of the inside of the nose section of the fairing. This is the air intake, which channels the air from the point of highest pressure at the nose, then channels it around the steering head and into the airbox, and from there into the engine.
Ducati swingarm and wheel cover bracket
Peter Bom: This is the rear end of the Ducati swingarm, with the bracket for the aerodynamic wheel cover attached to the chain tensioner. Above the bracket and at the end of the swingarm, we can see an accelerometer. The data from this accelerometer is probably being used to tune the mass damper in the GP19's 'salad box' to match the circuit and the tires being used.
It is always hard to tell where things stand in MotoGP on a Friday. The track is green, riders are working through the tire allocation to assess the best choice, factories with new parts will send the riders out to test them, to get feedback in the least important part of the day. Teams are still working through their checklist of ideas, some of which won't work, but having crossed an idea off the list, that can send the rider in the right direction. Or not.
It is even harder at a track like Brno, where a lap takes the best part of two minutes to complete. For a race which is 21 laps long, six laps counts as a long run during practice. Trying to assess race pace from six laps during FP2 is a very tricky proposition indeed. And as FP2 is usually the session where new parts are tested – the idea is, first establish a baseline with your existing setup, then put the new parts on to try at the end of FP1 or sometime during FP2 – that makes identifying patterns even more difficult.
What we did learn is that the Brno track is incredibly bumpy, more bumpy than it has been in the past. There are bumps at some crucial points in the track: Turn 3, the left hander at the end of the short back straight. Turn 8, in the stadium section. The chicane of Turn 11 and 12 and up the hill. Turn 13, the first corner of the final chicane before the finish straight. Complaints were shared equally, but opinions were divided on whether the track was becoming unrideable.
