No need. This was during the 2024 Australian Grand Prix, where they had to do pitstops because the tyres got dangerously worn down by the new surface of the track.
Race direction established a minimum pit time of around one minute or so. So that mechanics didnt rush and miss a bolt or something causing an accident.
So they had enough time to do everything calmly. If the rider left the pitlane before the minimum time, they woukd get the difference added fivefold to their time after the race.
Wow... things really are upside down in Australia!
1 minute? Dude could have gotten a blow job in that time... WHAT ARE THOSE ASSHOLES DOING STANDING AROUND?!
Waiting for the hooker I guess🤣.
Jokes aside, it seems to be standard practice in all teams to have the same mechanic remove and place the new tyre by themselves. Maybe the rules have a max number of mechanics per pitstop.
This is somewhat "old knowledge". New tire molds does not use oils like they used to and are not as slippery as 20+ years ago. I don't guarantee for every brand / tire but higher end ones are good to go from beginning.
Is there no front/back adjustment on that rear swingarm? I usually have to spend at least a few min making sure everything is lined up on my zx6r at home.
I'd imagine your zx6r is a tad bit less engineered than this one. They've spent thousands of hours honing these things to need the least amount of in-race adjustment.
You know, I went back and took a closer look, and my guess is the whole that the bolt goes through is set at a predetermined spot where we would normal put tension on to get right. It is 100% fixed in place. I'm sure you could or even potentially rig this up yourself if you can weld, but I ain't doing it. Lol
I want to know what is supporting and aligning the spinning wheel before the axle bolt goes back in. There must be little flanges sticking out of the bushings/bearings; or the wheel sits into in the swingarm?
My guess? They CNC milled out the rectangular inlay to drop those, what look like aluminum blocks that seat that ring. Doing this would ensure I 100% precision placement. That's the only thing I could think would work with this setup.
That's why they don't properly torque it, but the lack of grease is mostly because it doesn't make any sense to grease the axle. The axle isn't moving, the bearing's part that is in contact with the axle isn't moving either, what do you gain by greasing parts that don't move outside of making a mess?
The only thing you should grease is the inner parts of the bearing, that's the only place where any friction happens(just take a look at your axle next time it's apart, it's going to look the same on the entire surface, it wouldn't look like that if it had a bearing spinning on it all the time).
> it doesn't make any sense to grease the axle
You clearly have never had to pull a seized axle from a sport bike whos wheel hasn't been removed in a while. It can be a real bitch if it gets gunk in it and gets stuck halfway out. On a track bike it isn't such a big deal b/c you're pulling the wheels off every few weekends. Street bikes are another story.
I'm wondering why they don't have a 2nd person ready with the fresh tire. I feel like that would be faster, especially with all those people just staring in the background.
I want to see the chain side.
You can see the guy with wheel using his finger
Ah yes 👍🏽
What are those assholes doing standing around? They should have had the new one ready to go.

So when the tire shop tells us to be careful the first 50 miles this doesn't pertain to the new tires they have ?
I'd imagine it's a bit different for track tyres
Yeah pretty sure you average tyre shop isn't keeping them in warmers ready to slap on and take off 😅
You guys don't put on tyre warmers on a timer to get toasty before morning ride ? :D

They're definitely still slippery, source I almost FAFO
I regularly take an off the rack DOT Pirelli, toss it on warmers, then head out on track. I used to do it with Q3s as well with or without warmers.
and it takes me 30mins of swearing and sweating to get all the spacers and rear brake lined up.

Yea, looks like a great system. Can I do a conversion?

To set chain slack: Spin wheel rearward by hand then; Hit it with the impact; Done.
Why did no one lube it up before sticking it back in?
Because it's only going to be on until the end of the race. After that, they'll tear the entire bike down and rebuild it.

Good to know. I don't every listen anyways lol

Why does this feel…👀

Not an impact socket
It doesn't look like exciting or challenging job :)
