Tom's Tech Treasures: Analyzing MotoGP Tech Updates At Qatar, Part 2

Thomas Morsellino is a French freelance journalist and photographer, with keen eye for the technical details of MotoGP bikes. You may have seen some of his work on Twitter, where he runs the @Off_Bikes account. Peter Bom is a world championship winning former crew chief, with a deep and abiding knowledge of every aspect of motorcycle racing. Peter has worked with such riders as Cal Crutchlow, Danny Kent, and Stefan Bradl. After every race, will be publishing a selection of Tom's photos of MotoGP bikes, together with extensive technical explanations of the details by Peter Bom. subscribers will get access to the full resolution photos, which they can download and study in detail, and all of Peter's technical explanations of the photos. Readers who do not support the site will be limited to the 800x600 resolution photos, and an explanation of two photos.

Ducati “triple winglet” fairing on the Desmosedici GP19
Peter Bom: A tri-plane winglet arrangement must have quite a lot of horizontal surface area. By spreading that surface area over three wings, Ducati also reduces the risk of damage in case of contact with other bikes. Bikes with as much aero as the Ducati can barely be ridden at all without it any longer.

Peter Bom: Jorge is obviously still working on something he feels is very important: the ergonomics of the motorcycle. Here, and below, the contact points on the fairing which he is apparently using to support himself on the bike while riding.

You mention that the nut holding the triple clamp doesn't touch the cabron fibre, so I assume that the piece is bolted from underneath or is there some other fastening method I'm missing in the picture or otherwise ? I also see a little someone's photo on the triple clamp of what appears to be Dovi's bike. Any story on this ? 

Thanks for the amazing photos and descriptions! 


At least to me, it looks like the billet upper triple has a cylindrical protrusion/stand-off that the carbon fiber fits around.  The nut then still contacts the billet upper triple rather than the carbon fiber in this way, and the carbon fiber is only for the flex characteristics.

I don't get to comment often as I know diddley-squat about bikes, but I hope it's not true that ''Bikes with as much aero as the Ducati can barely be ridden at all with it any longer." ... Or maybe it is ... !

That’s great design right there.  Save the rider fatigue and doing so elegantly and what seems to be inexpensive.   Lorenzo’s knee pads are interesting.  Just for give under breaking or is he actually using the fairing as a contact point, pushing weight through them when cornering?
