MotoGP 2015

I'd use nitrogen if cost isn't an issue.

I wouldn't 'cause I check my tyres at home and top up with a track pump.

Slight change of subject: this is BSB but it's nicely done. https://www.youtube.com/watch?v=BJ969zo9O04

we have already discussed this.Pedro is so light he can run lower pressures and acheive the same tyre heating as the others.The minimum pressure is too hard for him.(at PI anyway,)

Just checked his weight, only 51 kg. I assume the MotoGP minimum weight is for the bike only?

Yes.

moto3 and moto2 are bike + rider.

I note Stoner weighed not much more than Pedro also, around mid to high 50's.
If the lower weight was a real disadvantage for the lighter riders, Would you not think logically they would support the minimum rider weight rule.
A taller heavier rider can move his weight around more but conversely a lighter smaller rider can move his weight further forward in some circumstances, Smaller riders can also tuck in further.
All up its six of one half a dozen of the other. Back in the old days a small light rider on the 125's was a real advantage, Open motogp likely not so much.
That said six foot plus motogp riders are very uncommon.

Stoner was taller though, which may or may not help. Pedrosa also kicked his arse in the light weight classes .

Look at Vazquez in moto3, he is as midget as midget can be, yet he's been there forever and won very few GP's. He does fly down the straights though!
I do think guys like Baz are at a massive disadvantage, I don't ever see him on a factory bike being able to live with the Spaniard's as he just sticks out too much.

I would argue there is a middle ground that is desirable, round the 60-70kg mark which I think lots of the riders fit into. Moar pies Dani?

Little off topic but one thing I noticed in indoor kart racing as a lighter chap, yes I had the straights over my heavier mates, but on the corners their extra weight combined with the slippery surface meant they were less sideways through the corners than me.

In this instance Pedro feels his weight is a disadvantage. He wasn't complaining when his bike could out perform Rossi's 'cause the engine on the #46 bike had to run lean to make it to the finish with the allocated fuel.

Simoncelli was tall, Rossi is just shy of six foot, Redding is tall, and now Baz. Can't think of any others but there may be more.

I don't recall seeing a closeup of the tyres after the race. That would have been interesting.

I'm still trying to work out if Marquez had planned his last lap, as MG is the final passing opportunity and it meant Lorenzo couldn't come back. Or, more likely, he knew he had one good lap left in his tyres.

Dani-boi has been racing at P.Is. for a fair while, seems odd his team hadn't given some thought to this issue earlier..
..like some personal ballast maybe?

Certainly there are a number of dynamic variables, with Dani-boi bodily contributing under 25% of the laden weight of the race unit..

All the electronic handling assistance complicates things a bit too, KC prefered to ride with them at minimum settings..

There must be a 'golden mean' of rider weight/strength/leverage to bike mass for ideal steering/handling/roadholding..

I weigh ~100kg togged up for a ride, but still prefer to ride bikes that weigh ~150kg, since such rider mass allows more direct
influence over what the bike can do, & big porkasaurus machines, to me - always feel like they want to, or will eventually, railroad the rider..


Gregg Hansford was another larger rider, & his size cost him G.P. wins - in the 250/350 classes - against smaller team-mates on equivalent machines.

Yeah but those taller than 5.9 are certainly the exception rather than the majority.
The tallest ones back in the 500 GP days (that come to mind) all rode the Lucky strike Suzukis
Terry Rymer and Scott Russell both over 6 foot. Kevin always looked to tower over the other riders but was only about 5.10.

Stoner was taller though, which may or may not help. Pedrosa also kicked his arse in the light weight classes .

Note the smaller classes have a rider plus bike rule minimum weight, so for Vaquez so there is no advantage in being light and small in the moto 3(other than being able to tuck in more.)

Exactly. The issue is producing dry air but it's not that difficult.

I'd use nitrogen if cost isn't an issue.

Just for the record. dry air is a requirement for scuba diving for entirely different reasons. a tank with enough air to fill a whole meetings tyres costs $10 a fill
Nitrogen tank filled when you break it down costs sod all per tyre but only with your own tank ie not paying the crazy even idiotic retail price.

IMO if you are scratching for fractions of a second advantage over the competition then using an inert gas ie Nitrogen WILL be worth time at the end of a long race simply by the fractional reduction in tyre wear holding a constant pressure offers.

Hi wondering if you can help? I've been out for a few days but appear to have lost the 'MotoGP 2015' thread. Seems it's been replaced by the 'Nitrogen vs. Oxygen in tires or other shit no one cares about' thread

Dont worry a month back it was the "This guy raced this bike here and I was there and it was 2stroke n faster" thread.
Then we all ignored J.A.W. and it got back on track.

...I have varicose veins...but that's ok 'cos VR is racing again this weekend...

Whose all still in the running for their start of season bets?

Not me, have been wrong for years as I have been betting on the midget bridesmaid.

Lots of people will be off though, with the strength of the Honda 2014 and MM you would have been thinking this year would be a sure thing... Go ROSSI!
