Super happy for Jack. I really feel that could unlock some real performance in him. He needed that

Poor old Fabio. Why couldn't he get arm problems while having a bad day rather than while riding to an easy win. Hopefully a quick op can sort the issue.

Finally, the energy drink brand angle we all need!

 

Are Rockstar Energy still advertising GP riders?

 

 

I don't think they are... they seem to be focussed with in dirt rider sponsorship (flat track, MX/SX).

Pedro Acosta... remember this name!

So far with his results, he is making even Marc's results in Moto3 look bad

No rider ever in history made debut into the smaller class with 2nd+1st+1st+1st - and with only 16. EXTREMELY impressive...

 

And one of those W he was starting from the pit lane...

I am tempted to say that Honda should just pack it in for this year and just focus on 22 already. They seemed to be a bit lost.

 

On the other hand...Marc finished relatively close to the leader, all while not being able to ride properly yet. And that's not even the biggest thing. He said on Saturday that because he hadn't been able to ride 100%, i.e. riding with a compromised style, they haven't been able to work on a setup yet so still riding around with a base setup from Bradl. And in turn, that has meant that because they have not been able to set the bike up properly, they haven't been able to use the harder tyres which is what the bike needs to extract its full potential. Taking all this into consideration, it's incredible he's where he's been an not riding around last 2 seconds off the pace. It also seems to me that with last year's bike (and Marc before the fall) they would have probably won and won easily today.

This said, and to turn to the negatives again, Marc did say today they do have issues with the bike. They're losing a lot to everyone mid corner to exit he said. (i.e. exactly where Yamaha's strength is). IMO This has been visible since the beginning of the season, the Hondas have crap acceleration and are struggling to overtake anyone. And as Marquez said today, there's no risk taking or riding around that kind of problem.

Finally Jack Miller showed up.

 

Moment of the race for me was Nakagami going around the outside of Aleix. Expected more from Suzuki during the race (and the less is said about Rins' crash, the better), Ducati looking really promising again and Vinales nowhere.

 

Now... I know this is a long season, but it's going to be between Quartararo, Mir and Bagnaia, isn't it?

Only if Fabio can have his arm problems solved.

 

I wonder whether there's something up with the current bikes (or brakes) that so many riders have arm problems nowadays. Do they pull so much more g during braking?

My understanding is that they are at close to 2g's in braking. I'd say it is due to the added aero over the past few years, and improved tires needed for the increased downforce. The 2g's would certainly be at the earlier part of braking, when the bikes are at their highest speeds, and get the most help from the wings. 

 

And most of this added force needs to be supported by the arms. This isn't like a car where the seat belts keep you from moving forward, and can support your body. I'm wondering if maybe there is a way to support the body under braking that takes some load off of the arms. Hard to do, due the rider needing to move around on the bike.

Lorenzo had a lot of problems that he sorted by using a better designed tank.  I'm not sure it was to help braking, but he said it saved energy.

 

Braking has hit 2g according to Mat Oxley

Part of why the surgery seems more prevalent now is that the minimally invasive fasciotomy is becoming more and more routine. Prior to the 2010s a mid-season surgery wasn't really an option for a contender and it wouldn't make the news in the off-season.

 

The braking forces are impressive nowadays but a production bike is more than capable of giving you arm pump.

I can easily see Mir winning it again at the moment. He's finishing fourth, fifth, while all around him yo-yo up and down. When we hit some 'Suzuki circuits' he'll be there to grab advantage like he did last year, because the guy has absolutely the right mentality, the bike is roundabout where it needs to be and there's already a lack of consistency everywhere else. Bagnaia is the potential fly in that ointment because he's probably quicker and at the moment is picking up seconds to Mir's fifths. But every season so far he's never sustained a breakthrough good run for long so I'll believe he can keep it up when I see it.

Along with aero I read a suggestion in Autosport that Ducati are leading the way with using the "holeshot device" (a rider operated mechanism that causes the bike to sit down on its rear wheel and improve stability in hard acceleration) on corner exits.

That was in the context of MotoGP bikes going too fast for many of the current circuits, which is a headache that the MotoGP technical advisers will need to deal with eventually.

Arm pump of course is specifically to do with excessive strain on the arms, causing temporary weakness. Motocrossers get it a lot, at much lower speeds. It could conceivably be down to how Fabio is riding the bike, although he'd probably rather get surgery than change a good thing.
