Would the introduction of a seamless gearbox to the Yamaha make them unbeatable?

Not unbeatable, just bridges the gap to Honda. Now they have to get the thing fine tuned because Honda has been using theirs for awhile now.

The North!
Has anyone actually listened to see if it is a seamless box?
Been away till now, not had a chance to see hear anything yet?
Kropo!?

Have ya bothered to go to motomatters?
From Friday:
<p style="color:rgb(0,0,0);font-family:verdana, arial, helvetica, sans-serif;font-size:13px;background-color:rgb(252,252,252);So Yamaha have brought their seamless gearbox to Misano. Being of a mind not just to blindly believe what Yamaha say they are doing, I naturally spent all of MotoGP FP1 on pit wall, watching the bikes come out of the 2nd gear final corner, and recording the sound of the gear changes to measure the gaps and estimate the length of time spent changing gears. Without even looking at the numbers, you could tell the difference: the gear changes of both Jorge Lorenzo and Valentino Rossi were audibly quicker, taking place without the usual bang of exploding fuel as the quickshifter cuts ignition. The difference was clear even when they were riding on their own, but when Bradley Smith and Cal Crutchlow went past shortly afterwards, the difference between the factory and the satellite machines was stunning. Where a large gap and small explosion could be heard when the Tech 3 bikes changed gear, the factory machines sounded smooth, revs dropping but continuing to drive, well, seamlessly.
<p style="color:rgb(0,0,0);font-family:verdana, arial, helvetica, sans-serif;font-size:13px;background-color:rgb(252,252,252);You didn't even need to hear the noise: just watching the bikes come out of the final corner gave you enough visual clues to see the bikes were using the seamless gearbox. The factory Yamahas were smoother, with less wheelie, and no movement of the rear when the gears were changed. This was clearly a seamless transmission Yamaha were using.
<p style="color:rgb(0,0,0);font-family:verdana, arial, helvetica, sans-serif;font-size:13px;background-color:rgb(252,252,252);Crunching the numbers, it looks like this isn't the quite the same version of the seamless transmission tested at Brno back at the beginning of August. Based on footage collected at the trackside back then, gear shifts were taking on average 0.016 seconds. A quick sample of the sound clips taken this morning reveals shifts have gotten faster, the average coming in at 0.011 seconds, with most hitting 0.010 or thereabouts. That is just two thousandths off the speed of the Hondas, which where coming in at 0.009 at the Jerez test before the start of the season. Yamaha may have delayed the introduction of their (ludicrously expensive, like Honda's) seamless gearbox, but it is well worth the wait. Yamaha have done it right.
<p style="color:rgb(0,0,0);font-family:verdana, arial, helvetica, sans-serif;font-size:13px;background-color:rgb(252,252,252);Both Rossi and Lorenzo were delighted with the gearbox after practice, Lorenzo telling the press he was 'very, very happy' with it, and Rossi echoing those sentiments. Lorenzo once again reiterated that in a straight line, acceleration and upshifts were like riding a scooter. Rossi corroborated that, saying that although the gearbox would probably not help on a single fast lap time, it was much less demanding to ride overall. 'I think is not a big improvement about lap time, about the top performance for one lap, but it is more stable in acceleration and the ride is less demanding. You can concentrate more on the line and try to take the bike more to the limit,' Rossi said. 'The bike is more easy to ride, and in acceleration, you can put the bike more precisely where you want for the next corner,' he added. Was the plan to use the gearbox for the rest of the weekend? 'The plan now is to use the gearbox for always. Or until a better one comes along!' Rossi said.

Is that the street name for it? Some people will do anything for a kick.
I couldn't ever get a Prince Albert, hell I can't even stand the thought of putting contacts in. And despite growing up in the 60s, have never sported an ear-ring. Girls were made for having stuff stuck in them, not blokes.

Now, back to the regularly scheduled programme
Can you (or anyone else) tell me how the actual mechanics of shifting have changed for the rider? I take it they don't use the clutch, just bang it down into the next gear? I have never ridden anything with a quick-shifter or known anyone that has.

Listening to the commentary during FP1 today it doesn't sound like from a rider's perspective technique has changed. The gearbox is simply pre-selecting the next gear to make the transition smoother. I could be wrong however.
