MotoGP » Ducati rejects ‘winglets are dangerous’ argument


I have to laugh when I read comments about aerodynamics from posters whose only experience with wings was on a Kentucky Fried Chicken. With a new MotoGP top speed of 219mph being recorded this season no-one can ignore the importance of wings in reducing LIFT at speed. Because LIFT at speed can launch a bike and rider airborne with obvious consequences, therefore there is a strong argument that "Wings" are essential for safety at high speeds. Also regarding safety, engineers all know that the "wings" only need strength in one direction (i.e. vertically down) to transmit downforce and that they can be designed to collapse when force is applied from any other direction. Viz Inannone’s broke off easily. Regarding “looks”, beauty is in the eye of the beerholder and are a styling feature of some cars. If we outlawed progress we’d still be riding wooden wheels

MotoGP » Ducati rejects ‘winglets are dangerous’ argument


bringBACKthe990s: [Riders are already complaining about the turbulence behind the Ducati's at full speed. It is a safety issue. But more importantly, it's a "passing/spectacle/racing" issue.
. It is easy for riders to complain about something that can't be measured, with the sole aim of reducing their competitors advantage. There are no figures or examples to prove that such turbulence is magnified by wings

MotoGP » Moto2: Immaculate Lowes dominates for Jerez win


People are talking about Rins joining Yamaha. Sam is marmalising Rins. Sam is leading the Championship. Sam has proved in the past that once he gets the winning recipe he will keep on winning. Yamaha must be asking the question " How much would it cost to buy Sam out of his Aprilia contract?". This is my 4th attempt at posting a comment on this thread. If the "Unexpected errors" continue I'll be ex-Crash.

MotoGP » Six wings for Marquez!


With a new MotoGP top speed of 219mph being recorded this season no-one can ignore the importance of wings in reducing LIFT at speed. Because LIFT at speed can launch a bike and rider airborne with obvious consequences, therefore there is a strong argument that "Wings" are essential for safety at high speeds. Regarding the cut or penetration arguement, most engineers are aware that a leading "knife edge" is NOT the most effective shape for a "Wing" and that a rounded leading edge and a tapered trailing edge are needed ( look at any aircraft ! ). Also regarding safety, engineers all know that the "wings" only need strength in one direction (i.e. vertically down) to transmit downforce and that they can be designed to collapse when force is applied from any other direction. This is prototype racing and aerodynamics have been ignored for too long. It is interesting to see where it will lead and what benefits will result and be transferred to road bikes.

MotoGP » Moto3: Incredible Binder last to first for debut win!


A couple of years ago I picked out Fenati as one of the riders who would blast to the front of Moto3 and swiftly move on up the classes. Clearly VR46 agreed with me. However, Fenati is now showing as good, but not championship material. I don't expect Fenati to be on a VR46 bike next year. The 16-year-old Bulega is proving to be the one with real prospects and again VR46 is agreeing with me. Oi , Vale, where's my cheque ?

BSB » Ellison on top in slippery conditions


cossiegaz: Off topic here but is anybody else getting a VC011 error on the BT sports app using iPad or iPhone? Any idea how to fix it before the race?
On PC I frequently get " An unexpected error has occurred, please try again in 5 minutes". But after 5 or 10 minutes, oe even a day, that thread is no longer usable. I'm beginning to think Crash.net was named after their server performance.

MotoGP » Pedrosa: It’s lucky I don’t have wings…


With a new MotoGP top speed of 218 mph being recorded this season it is now ever-more apparent that aerodynamics aids are a necessary evil. Aerodynamics affects every rider and machine. It is an unavoidable consequence of speed through the air and in the interests of rider safety on-track and on-road it is right that manufacturers should explore how to manage it effectively. Until it has been evaluated thoroughly no-one can predict what benefits may be discovered and how the dangers can be minimised or eliminated. That includes the manufacturers and aerodynamicists, or they would not be experimenting. Most keyboard warriors don’t even realise the importance avoiding LIFT at speed. What we do know, right from the start, is that “wings” need strength only to resist DOWNforce and they and their mountings can be constructed to fail when exposed to force from any other direction i.e. from underneath or sideways, and therefore be collapsible under impact from unintended occurrences.

MotoGP » Riders react to Bautista pit lane crash


ARins42:
shpongled: Extra time lost in pits due to lower speed would be the same for all riders so it's irrelevant. Smart guy MM hahaha.
like has been said in the article, it wouldn't be the same for all riders in case of a real flag-to-flag race such as Misano last year or Aragon 2014 where it is up to the rider to change bike.. in that case, those decided to change bike would lose more time in the pit..
True, but the time lost varies from circuit to circuit anyway, dependant on the length of the pit lane entry and exit. The teams already take this unavoidable time loss into account, so they would also take slower pitlane speeds into account as a matter of course.
