GPS is banned, but that hasn't made a bit of difference. They use the inputs from the timing loops, plus lean angle, speed, and distance travelled, to work out exactly where the bike is on the track. Power delivery, torque and horsepower are all dialed in appropriate to the virtual track map in the bike's ECU.

Hayden's problem at Estoril was that the bike thought the T3 timing loop was the starting line, and so the power delivery was half a lap wrong. With a big fast front straight and a tricky, technical rear section, including the slowest chicane on the circuit, you can imagine how well that went.

Lorenzo's problem at Mugello was taking the short cut back to the finish line after Casenove Savelli, cutting off the rear half of the circuit. Did basically the same thing as Hayden, confusing the bike and thinking it was half a lap away from where it was. That's a bit less of an issue at Mugello than it is at Estoril, as the track is more flowing, fewer really slow sections.

Yikes.

Thanks for the earlier page link. I had looked but obviously not that well.

No. Grains of truth expanded to create a heady brew of speculation.

I believe they are allowed to change the gearbox. If that translates into a seamless gearbox slipping right in or not is a different story.

Not sure if the new gearbox will require new case halves

The question is, will a seamless transmission use the same size gear shafts? Those shafts may be bigger than a conventional transmission, to house the additional components to make a seamless gearbox work. This is not a question I know the answer to, but it may not be as simple as it appears.

Yes many variables including increased shaft length/spacing of bearings hence my crankcase halves comment

A question for Neil Spalding... I've missed some of the practice so haven't heard every word from the Eurosport gang this year.

Ben says some interesting things about Yamaha, Ducati, WSBK, tires in Moto GP, and so forth.

Sounds like an extended version of his tweet announcing his departure from Yamaha. I hope he pulls a Barros and gives some real details on his way out of MotoGP.

Depends. MotoGP should be the pinnacle of all development tires included. Instead of degrading the tire development why not limit horse power? If you simply want close racing then put every one on spec bikes. I want to see the best riders on the best bikes. I think the problem is the manufacturers have too much influence on the rules and favor their own development.
