MotoGP » Casey Stoner leaves Honda


The CEO of Ducati treated Stoner badly. The rank and file knew what they had. The CEO moved on after he sold the company and collected his bonus. The current CEO is a long term biker guy. Stoner has value to the brand, whether he races or not. He won races, despite the bikes flaws. In reality, it's unlikely he'll be as competitive as he was. It's almost impossible to get to the same level. However, if Rossi can still win races after his woeful performance at Ducati, Stoner can probably win races. Championships are another matter.

MotoGP » Official: Casey Stoner returns to Ducati


Some of the comments here are pretty funny... Stoner paid out on Ducati when he left... It's true that Stoner was unhappy with the way he was treated at Ducati. Del Torchio, the CEO at the time, believed the BS in the press that it was "the bike". He then belittled Stoner for his health problems, refused to fund the racing effort (more than the minimum) and was willing to pay other riders more than Stoner was paid, despite CS's successes. Stoner went to Honda, doubled his money, and watched the "great Rossi" humiliate himself. Meanwhile, Del Torchio (not a motorcycle guy at all) sold Ducati to Audi, took his bonus, and left the company. You can't develop a motorcycle when the company won't spend money on parts. Riders only give feedback anyway. Engineers develop bikes. It's VERY difficult for a rider to take extended time off and come back with competitive speed.. Some of the best fail. He is most likely doing this for personal entertainment. After the toxic Rossi sook fest, this is

MotoGP » ‘Time is a gentleman’ in Marquez, Rossi rift


cfsteezy: drivel... And people keep saying 'rossi only had pace for 4th in valencia'... its cuz he burned up his tyres fighting through the pack. ...blah blah blah'
Are you saying that Rossi burned up his tyres at 7 tenths of a second per lap SLOWER than the front three riders? Especially considering that no-one prior to Smith even tried to compete with him, they just let him through...and even then, he only made two more passes. Were you watching the same race??? Maybe I need some yellow tinted glasses. They apparently make the world look amazing.

007: ... active aerodynamics. ... It is prototype racing after all, the test bed for future technology. I feel that limiting things to like one tire manufacturer or one size fits all electronics, different bike brands different characters, this only puts a leash on development. ... If they really want to bring the field closer together they should start by having the manufacturers supply competitive equipment to these teams, not a three year old bike, ...
Great post. My sentiments exactly. Prototype racing should involve prototypes.

Yirmin: Sorry, but when the rider is turning this isn't going to help as much as it will hurt. A bike isn't like a car that stays mostly parallel to the road in a turn, so on a car a wing keeps putting down force on the wheels... but on a bike that is leaning at a 45% angle the wing is putting as much force pushing out of the turn as it is putting force down on the wheel... ...
Winglets develop lift and drag. In the case of these winglets, Drag is proportional to the speed squared. I can't remember the lift formulae... These bikes generate enough data to allow them to measure or potentially derive the L/D net effects with use. Presumably they study the data as they come up with their modifications. I can see how they would help with braking, but anti-wheelie is a bit more difficult, because it is more relevant at lower speeds than you'd expect these to have much effect at.

RealRacingCampaign: Surely if the desired outcome is more weight into the front wheel, then the wing might be better as part of the mudguard? Then it'd act on the lower suspension legs directly to the tyre, without affecting the suspension fork action? Not easy to incorporate maybe, or maybe they do want to pitch the whole bike fwd with these winglets?
They're above the suspension because you always want to minimise unsprung weight. The wheels follow the road surface. Less unsprung weight allows the wheels to maintain better contact with the road. Winglets on the fork bottoms would create problems.

There's no way that bike winglets could have the comparable impact to F1 wings. F1 minimum weight is about 700kgs. MotoGP is 160kgs. Assume a driver / rider weight of 80kgs geared up, but ignore fuel weight... So, the bike has about 30 % of the weight, but much less than 30% of the wing size. Further, much more of the F1 wings operate in less directly disturbed air, further from the main fuselage. Disturbed air offers much less lift, and much more drag. Try sailing through on the leeward side of a yacht on a windward beat and you'll see how it works. The closer you are to the windward yacht, the more effectively you are "lee bowed". Really, these winglets are a small contributor. Obviously, every bit makes a difference, but they're not a quantum leap. My only complaint is they look ugly.

Except they aren't going to weigh much and would be easier to deal with on the unsprung part than on the sprung bike which would vary the way the bike felt based on the speed and force the wing was exerting.
Weight is nothing more than mass which is subject to the downforce of gravity. Aerodynamic downforce has exactly the same effect.
