MotoGP » ‘Thumb brake’ appears on final day of Honda test

physics: Well applying rear brake doesn't get your rear in the air. Thumb brakes are usually used because in right turns you stand on your toes on the rear set and can't use the rear brake. Rear brake usage actually makes the whole bike squat when used with the front, so less rear wheel air time.
Given your user name, I'm sure you're aware that most of the braking is done with the front brake, and when applied hard enough, the weight transfers almost entirely onto the front wheel. If you watch Marquez, his rear wheel is often either skipping in the air, or completely unloaded until he tips it in. He initiates most corners over the front wheel. It is quite brilliant, and his corner entry in particular is poetry in motion. It looks loose, but he does it at will. The rear brake will bring a wheelie under control, or stabilise the bike in some cases. Maybe they have a better feel using a thumb control. They don't need much force for it to be

35edme: The teams as well as the FIA, being aware of a problem with the sensors had already decided on an accepted offset. This went some way towards satisfying everyones' c
They may have been additional error from the sensor if it lost calibration. The error may have changed from the one initially corrected for.

F1 » Kate Walker: Fuel madness

People here imply that RedBull will use their own method to show their fuel flow. Which is illegal, because the approved by FIA method is the sensor they provide and the back up system approved by FIA. We all agree on this, correct? They can't win this, correct? I bet you they won't even try... What they are PROBABLY (as my opinion) will do is to, with the help of their measurements and third party sensor analysis lab, together with FIA officials find and document the unit error of the sensor that was in the car of Dan during the race. When they know the error they will recalculate the real fuel flow, measured by the homologated by FIA sensor. Then we have the two possible outcomes... And I must repeat it will be done with the homologated FIA sensor, the legal way, no rule bending.
