dry rain dry

<div class='quotetop'>QUOTE (gary @ Apr 25 2008, 04:04 PM) <{POST_SNAPBACK}><div class='quotemain'>i have been thinking of this for a while.

the race starts on slicks and after a few laps or so the rain starts,then the riders are on the option to chance the rain or go in to the spare bike that has rain tyres fitted.

those who opt for the rain tyre come in etc and out again,a few laps later the track is drying,do the riders have the option to go back in and change back to the original bike,and does this bike keep the original tyres that it started ? or can the crew put a new set of slicks on ??

this senario as yet to happen ( cant wait to see what happens )

any positive views on this.
i may contact dorna regarding this tyre change senario...can you imagine if this has not been discussed in the boardroom. <div class='quotetop'>QUOTE (1.18.17)<div class='quotemain'>Unless the race is interrupted, after the leading rider has passed the
finish line at the end of his first lap, no further changes of machines
are permitted. After this time, in the MotoGP class only, the 2 following
procedures will apply:
– If the race has been declared wet (Art. 1.20), changing from a
machine equipped with rain tyre to a machine equipped with
intermediate or slick tyre, changing from a machine equipped
with intermediate tyre to a machine equipped with rain or slick
tyre, and changing from a machine equipped with slick tyre to a
machine equipped with intermediate or rain tyre is permitted at
any time during the race.
– If the race has not been declared wet (Art. 1.20), the same
machine changes as mentioned above are permitted only after
the white flags have been displayed around the track.
In both cases, tyre warmers, changing tyres and adjustments are
permitted on the machine in the pits and in the pit-lane.
The spare machine may remain inside the pit box until such time
as it is used in the race, but any exchange of machine must be
made in the pit lane.
<div class='quotetop'>QUOTE (1.21.8)<div class='quotemain'>Riders may enter the pits during the race, but taking the
motorcycle inside the pit box is not permitted. In the MotoGP
class, in the case of an exchange of machine during a race
(Art. 1.18.17), if a machine that has been active in the race
enters the pit box, this machine is deemed to be retired and
may not be used again in the race.
Refuelling is strictly prohibited.
Any infringement of this rule will be penalised with a
disqualification.So if the motorcycle is taken into the pit box, it's done for the race.

<div class='quotetop'>QUOTE (gary @ Apr 25 2008, 04:43 PM) <{POST_SNAPBACK}><div class='quotemain'>so if that is the case.. a rider will have to finish the race on a treaded tyre in the dry ??
that will mean massive tyre wear and therefore the race speeds will be less than if on a slick tyre in the wet ?? ... is that correct in my understanding ? The implication I get is that by pit box they just mean inside. They can't pull the bike inside the garage and reenter it. Given that they allow working on the spare bike while it's in pit lane, it appears that the area outside of the actual garage doesn't qualify as the "pit box".

Thats my understanding too, and in fact I think it has happened that a rider has changed bike twice in a race. Didn't Edwards do that last year?

Even a badly worn rain tire would be be faster in dry than slick on a really wet track, besides your senario is rather constructed. It's not likely that a track go from all dry to all wet to all dry again within a race. Worst case senario would be one going in too early before it's really wet and and rain stop just as he leaves the pitlane. Or more likely it gets all wet on a very hot track really early in the race and then a drying up track will destroy the tires at the end of the race, but in reality they all will probably stay on the wet tires as a change take too much time.

yes, that what i thought too
a race is "just" around 45minutes, and i can´t see the scenario where it is started on a dry track, then get Wet enough to make sense to change on rain-tires and then getting dry enough to change back.

i think this will never ever happen

I think so at Le Mans, but I can't remember for sure.
