Tom's Tech Treasures: Aero Packages And Seat Units Tried At The Brno Test

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, MotoMatters.com will be publishing a selection of Tom's photos of MotoGP bikes, together with extensive technical explanations of the details by Peter Bom. MotoMatters.com 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 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.


Suzuki's new winglets, first tested at Brno
Peter Bom: The Suzuki winglets look a bit like those used by KTM, and the latest version of Honda's aero package used by Marc Márquez in Austria is heading in the same direction. It's no surprise that neither the Yamaha nor the Suzuki have lower spoilers on the side of the fairing. They have the least horsepower, and so don't really need them.

Excellent images once again. Thanks Thomas, David & Motomatters.

Peter Bom: The Suzuki winglets look a bit like those used by KTM, and the latest version of Honda's aero package used by Marc Márquez in Austria is heading in the same direction. It's no surprise that neither the Yamaha nor the Suzuki have lower spoilers on the side of the fairing. They have the least horsepower, and so don't really need them.

The Yamaha and Suzuki are inline 4s and thus wider than the V4s - does that play into the lack of spoilers on the side of the fairing?

Good ones! Thanks.

The aero looks good to me now. Form, function, beauty, tech we laypeople can see. Until Jack's old Fokker Triplane buzzes into frame to shoot someone down. Ugly shite! I like the flatter upper fairings too. Wheelcovers? Give me some time I suppose.
;)

Both the Ducati and KTM bikes sure catch interest. We know Red's NASA de Italia. (And it brings a smile that we officially call it Salad Box, and accept that it is an active dampener). Curious when the salad is being tossed, and how. Seems anti-Yamaha in that Blue went for tuning fork at core, and Duc dangling an add-on re-tune.

Orange is doing some individuated and bold things. Less imitation, more innovation. One part old school (tube frame, in-house suspension) and one part Ducati freshness. Bold! Wishing them great luck. Listen to Dani. Let the 2 Yamaha guys go elsewhere. Binder, Oliveira, and a few more of the steps forward we are seeing? Great! Impressing.

Suzuki, bless you for being at it like you are. Shoestring budget, conventional everything, sparse personnel, and STILL near the front. Does looking at "42 in Blue" make you happy too? #20 Aquaman? Warms the heart.

Honda is the Death Star for me. Puig needs a silly black helmet. Not a fan of their overfunded under handling over motored monster. Not a thought, just a visceral feel. I don't like looking at it apparently. Hmm!

The new Yamaha seat section looks great. I am w Maverick, narrow between the knees and let the rider shift onto the side of the bike. Like a Duc twin. Keep it coming Yamaha. You and Suzuki, 20 more horses in the stable please. Help us motor grunt engineers, you are our only hope.

So Quatrocopter has the carbon forks now, will he (did he already?) get those missing 500 rpm? What has Mr.Morbidelli to say to all this?

Thanks a lot for all those eyecandy photos and the braintickling analysis!

I am happy to be so described. But subbing for this site is a total no brainer. 

Dunno how David does it, hope he's proud of his ongoing and improving achievements.
