the potential problem as I see it...I seem to recall the Honda being that much harder to jumpstart after offcourse excursions due to this transmission and Casey Stoner having a conniption fit about the corner workers not doing enough to help him restart it....will Yammyhammer suffer the same injustice now?

"Reports from the track were that the bike made a horrible noise as Rossi was downshifting, just before he ran off track, and that would appear to suggest that the gearbox may have been a problem."



I'm betting it won't hit a race 'til next year.

you don't make design decisions based on what might happen when you crash

no..but if you are smart, you consider what others have experienced when you implement new to you technology and hopefully plan for contingency!

Google Translate makes it sound like it will not fit engines currently in play, but can be fitted to Rossi's and Lorenzo's single remaining bullets.

Given the points situations for Rossi and JLo, I think it'll be next year before it races.

(comment on the MM article)

...the factories have been forced to make an expensive seamless shift gearbox because the rules don't allow an inexpensive seamless shift gearbox to be used (i.e. existing dual clutch).

..and they're trying to cut costs in MotoGP?

..and they're trying to cut costs raise Dorna's profits in MotoGP? 

Fixed it for you.

~~~SNIP~~~

...the factories have been forced decided of their own free will to make an expensive seamless shift gearbox because the rules don't allow an inexpensive seamless shift gearbox to be used (i.e. existing dual clutch).

~~~SNIP~~~

Fixed that part too.

Fixed that part too.

yes, they decided to make a seamless shift gearbox, but dual clutches have also been banned for the last 2-3 years.

if that's gonna be what it takes to win the championship, they didn't really have much choice since honda definitely already has a well sorted one.

[Triple J]

Why the ban in the first place?

Why the ban in the first place?

No kidding!  It's prototype racing.  Set limits on displacement, weight & fuel capacity.  After that run what you brung.

Makes life a whole lot simpler.

Dual Clutch system is apparently ( as I understand it ) too close to being an automatic transmission and they do not want an automatic transmission machine....though given the way they run those bikes currently with telemetry and everything with the throttle and all the other data programmed in with GPS on the track and how much of the bike is doing this, that, and the other...they are damn close to being there now it seems.

banned since 2010.

I know they don't use GPS...but like I seem to recall Hayden's bike recently "forgot" where it was on the track and was running very wackadoodle wrong at one point...so I know that even though they don't use GPS, they do program the bikes to be at certain powercurves and have certain expectation of charachter at differing corners and program the riders data into the bike to be at the most potent delivery based on a patterned algorythem
