    If i ever make it to a GP Jerez i will go to that restaurant. But i might go "Rioga"(is it wine??) instead of tonic water. Nice control David, but like you said a fair bit of work to do.

    I think there's a bigger problem with wings on a production motorcycle than just the cost. Firstly, I think there are going to be safety concerns, if not already laws against hard/sharp protruding parts. Secondly, wings can only be used together with wheelie control. Imagine doing a wheelie (popular entertainment on many fast bikes, important part of the fun) with those wings: beyond a certain angle they will generate lift, help increase the wheelie, and things will self-amplify. That can become rather scary at high speed.

    The alternative would be to make the wings self-adjusting, so that they rotate to give at most zero lift, but that seems to me like becoming a very expensive way of achieving a very small advantage, judging from what we've heard from riders.

    The thing with wings on a motorcycle is: it's only good for keeping the front wheel on the ground, it does not give you extra grip for going faster round corners, like on a car. Yes, the front wheel will be pushed on the road more, but unlike on a car, the wings will also push the front outward more. So I'd guess that all the grip you gain, you need just to counter the outward push. It should help in those places where the front will would otherwise lose contact, like over the crest at the right-hander going onto the back straight at Jerez.

    Another thing is: if the wings are very far at the front, they can be kept the smallest, because they will have more leverage. That makes them cause less air resistance for the same amount of downforce at the front wheel, but if they are getting effectively beyond the front axle, they will take weight off the rear wheel. I noticed that the latest large moustaches of the Yamahas are quite on the edge of that, at least so it appeared on tv. I wonder if that may have been a (small) factor in the high-speed wheelspin problems.

    All in all, it's better just to get rid of them, it seems to me (and most people). But we might get some interesting noses instead, who knows...

    I am all too deeply aware that I am one of the most fortunate men alive, and Jerez makes me appreciate that doubly so. Firstly, I am married to a wonderful woman, who is my perfect match and who understands me perfectly. Secondly, I make a living (barely, but I do make a living) writing about motorcycle racing. Thirdly, I get to travel to amazing race tracks around the world, and take in the sights (sometimes, though all too often it is airport - hotel - racetrack - hotel - airport). Fourthly, I get to stand up close at the race track, and see the bikes and the riders at very close quarters, and get an appreciation for what they are doing.

    At Jerez, I get to combine all of that with a good meal. The bar under the stands at Turn 12 is a fantastic place to sit and watch, and highly recommended. Food is solid Spanish fare, well cooked. One of the things I said to Tony and Cormac as we sat there was how very civilized it was.

    One thing, though: it was tonic water, not Rioja. I had a lot of work to do in the afternoon!

    "One of the joys of testing at Jerez is taking lunch at the restaurant under the grandstands between Turns 11 and 12. Sitting there with photographers Tony Goldsmith and Cormac Ryan Meenan, we compared notes on the bikes coming through."

    Which vintage of Rioja were you sipping with your paella?

    Ban the strakes. They'll never see production without a nice increase in costs to already expensive machines laden with electronic trickery.

     

    Michelin have done well to be just at the beginning of the era.  Riders always complain about tires no matter how good they are.  Michelin has done well so far, implementing safety first and flying tires out at their expense when problems have risen.
