Good news but one will it be enough and two are they sure it's ready? If it's not enough will it be a black-eye on Yamaha factory? If it causes a mechanical failure then it will definitely be a problem for its racers trying to close the gap to the Hondas. Nevertheless, it will be interesting to see if it helps or not this race.

i think yamaha must have done enough reliability testing since its last test.....

plus the fact that it will be further tested for 4 fp's by both riders before the race...

but the thing i am looking forward to the most...

crutchlow's post fp interview explaining how the factory yamahas are stronger in braking, acceleration because of the greabox

Great news, they allready test the gearbox and they aprove the improvements!! Aim shure Yamaha will be overall faster and will be very interesting to see what this new Gearbox can bring in terms of new types of setups.. I know that is just coincidence but to make the debut of somethingh that has been talck for long time at Misano, Rossi home race must be extra motivacion for him.. I can t wait to wach i hope Yamaha Rock tha Sht cause aim tired of Racecraftter bla bla of HRC..lolo

Sounds like CVT / AP-style torque-convertors are being used ( I'm happy to be corrected ). I reckon the system will be reliable as I imagine there are fewer moving parts than a standard system....... Overall lap time won't be dramatically affected, but overall race times could tumble ( relatively speaking ).
I wonder how it will affect braking & turn-in ( if they set it correctly maybe it could help the Yam's brake issues ? ).
Interesting stuff!!!

I'm not sure I believe " better for the rider but won't affect lap times".
If it is a smoother and quicker shift and upsets the bike less, then the rider will be able to brake more accurately, accelerate where previously they couldn't because of power surges, and because it is less jerky the traction control and all the other electronics will have smoother input and therefore smoother output.
I honestly think that Yam are down-playing the advantages and that JLo and VR46 will both take a step forward.

re: "Good news but one will it be enough and two are they sure it's ready?"

that's a NO on both questions.

re: "If it's not enough will it be a black-eye on Yamaha factory?"

doesn't matter. they're putting it onto the shoulders of the riders. and I suppose, these are big boys, they can handle it.

re: "If it causes a mechanical failure then it will definitely be a problem for its racers trying to close the gap to the Hondas."

again, doesn't matter. they know if they play it safe..? it's 99% likely they're going to lose the championship. if they take a risk...? the odds of losing the championship reduce to 98%. it's only a 1% improvement, but technically that's better than what they got. damned if they do, damned if they don't.

transmission or not, just making their final engine last 6 races is going to be a feat.
