"lap times were faster in 2012 due to the higher speed, although braking time was longer."

This "although" shows little understanding of motorcycle and general physics. OF COURSE braking time will be longer and the braking point will need to be earlier: If top speed increases, you need to scrub-off more speed to enter the corner.

By no means does this "longer braking time" mean that corner speed has necessarily lowered. In fact, supposing that both 800cc and 1000cc motorcycles enter at exactly the same speed the 1000cc will be going faster than the 800cc up to the braking point of the 800 even if it has hit the brakes a few meters earlier.

Jack if you go to gpone.com you will see the slides from the presentation and what you say is wrong is a direct quote from yamaha on one of the slides.......

@ slider: I have a degree in physics and what I say derives from this. I have no idea about what is published on gpone.com

I've made a typical telemetry graph showing exactly what I
mean. Preceed the following address with "Eichteeteepeedoubledot":

I presume cornering and braking traction to be the same for both bikes which is very close to reality.

great information. now please ban those carbon disc brakes and allow ferrous-metal discs instead. it will increase the braking distance tremendously, and in turn we can see more overtaking as most moves are done under braking. this will change the emphasis from outright power and top speed, to acceleration and stability/traction out of corner.

even from R&D point of view, it will be more relevant to the production brakes used on the streets. face facts - electronics from MotoGP have found their way to production bikes, but carbon brakes? 22 years and still not there.

They can bring all the tech to the road they want, the R1 is still the heaviest worst liter bike of all japanese bikes. Read any test this year ... Not winning any test. The Honda is still beating it even without all the fancy junk.
