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.
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.
