MotoGP Aero.....

[Andres125sx]

Dorna asked Honda to NOT publish the telemetry to stop the bad atmosphere wich was stablishing at the paddock. That speaks itself

I haven't seen any evidence that MM has complained of an injury to his person, attributable to a winglet-to-body contact.

Because he was not injured.

But the picture shows that was only a coincidence, and serious injuries could happen on a future if similar winglets are allowed and all teams start using them. Remember this is new and there´s no previous experience, only two bikes used that winglets past season but even so they caused a dangerous situation.

Think about a pretty common situation, some rider being way too optimistic about his braking abilities and trying to overtake someone at the inside. Depending on the situation the rider at the outside might not see him coming, and could be mowed down by the other rider. If that bike has winglets, there are huge chances that winglet will be first part colliding with the bike/rider at the outside. Imagine the mass of an uncontrolled bike+rider colliding with someone kidneys through a winglet...

I really can't see a huge safety issue with the winglets. On a motorbike there are far worse things. High speed rotating wheels for instance, or foot pegs and handlebars with the bikes mass behind them (or worse, Google why Daryll Beattie has different shoe sizes). A few flimsy carbon winglets, riveted to a flimsy carbon fairing will not even scratch the racing leathers.

They do look silly, but that's a different discussion.

Anything creating downforce at medium speeds (the purpose is to avoid wheelies wich means the bike is accelerating strongly, ergo far from top speed), wich will also be travelling at 350kmh, cannot be any flimsy or it would break itself at the straight

But even if it´s flimsy, if it collides with a rider at the "correct" angle (perpendicular) then the winglet will only support compression efforts, and carbon fiber does not break easily at compression. If it was designed to resist flexion as it was, compression efforts will not break it easily at all.


Maybe it´s just that I don´t want MotoGP to follow F1 route, but as a rider myself I wouldn´t like any bike with those appendices around me, collisions between bikes and riders are not that weird at all, they´re quite common.

I think concerning the risk of cutting it's fairly ok. The rulemakers luckily had the sense to enforce mininum radii for the edges. Maybe you'll get bruised by it when it pokes in your side, but that might be it.

I think the real danger comes from if these devices will be/are been used to increase cornering speed. Aero devices can stall suddenly, and you don't want a loss of grip midcorner.

But these are concerns. Ultimately I do have faith in the decision making skills of motogp, as they know best.

So, even though no dire consequences have occurred, winglet-type aero devices are to be banned, from next season, a lame call IMO..

So what is not to stop the designers from adding protrusions as part of the body work that look like winglets?

Looks like the days of winglets on MotoGP are numbered, banned effective with the 2017 season.

A shame really, I enjoyed seeing the aesthetic diversity the add-ons added.

Or slat/slot/fence-like aero-devices - within the outer fairing skin - that act like winglets..

The fun thing with MotoGp racing is that its much closer visually with street bikes. Prob the biggest issue with the winglets are that they can't really fit on a fireblade or R1. The manufacturers have a shared interest to keep it pretty clean and I would guess that Dorna and the FIM is open for any kind of suggestion in this area.

In basis a lot more sensible then F1

By the way, this all happend before, when you had enclosed front wheels inside the fairing. They changes the rules so the bikes would look like normal bikes again.

[J.A.W.]

Nothing to stop you putting winglets on your own road bike, except being labelled a poseur, is there?
Maybe we'd have seen them on homologation superbikes for SBK racing series, if there was a racing advantage to them.

Notwithstanding the pending ban at the end of this season, Ducati fielded yet another fairing winglet type for Austria,
- this time it was closer to the now regular Yamaha 'moustache' form, albeit including a longitudinal fence, as well.

[J.A.W.]

The British G.P. at Silverstone showed some new aero, with the winning Suzuki utilizing fairly rectangular planform winglets in the 'moustache' position.

M.M.'s Honda featured Yamaha-like triangular strakes projecting forward in the 'moustache' style, & Cal C's customer Honda now carries winglets too.

The factory Yamahas now have flat fence/end plates added to their nose strakes.

Ducati's winglets appeared to be unchanged this time.

[J.A.W.]

Dani Pedrosa won at Misano, & he - unusually- does not use the winglets on his factory Repsol Honda.
The other machines appeared unchanged aero-wise for this race, however.

Thanks to member 'scuderiafan' for finding this useful link - which gives Honda Moto GP boss Nakamoto-san's topical views,
inc' why their little guy, D.P. - races sans 'winglets'
