Carrying maximum corner speed involves having the tightest turning radius that traction allows for (maximum lean angle). How do you reach maximum lean angle? By evenly loading both the front and rear tires or slightly favoring the rear. If your sliding the front tire than your not at max lean angle which is reason #1 why that technique would only make your lap times slower. Reason #2 is sliding in general isn't a very effective way of slowing down. For example try skidding the rear tire under braking compared to modulating it to maintain traction.... which stopping distance ends up being shorter? On a correct corner entry the front will be fully loaded and only slipping slightly, at this point the rear usually has a lot of traction left to give. So if you want to scrub just a little speed why not simply use the rear brake? (which is what Moto GP riders do by the way). This way there's no sliding involved or weird on/off throttle chopping. Sliding the front is very risky and doesn't have any benefit to lap times what so ever.

There's plenty more reasons why purposely sliding the front would make your lap times slower but I'm not going into all of that. Just for an example think about this one. At 80mph your traveling at 117 feet per second. In the time it takes you to make your throttle blip (maybe 0.5 seconds) you've traveled about 50ft. Now imagine what would happen to your lap time if you simply adjusted your racing line to be either on the throttle and accelerating or at maximum lean angle for that 50ft instead of sliding the front tire and pushing wide.

A lot of words from someone who knows precisely nothing about riding a MotoGP bike to (and beyond) its limits.

I also know precisely zero about riding a MotoGP bike. Just like everyone else here I suppose... this thread really ought to be renamed 'the armchair experts guide to MotoGP riding!'

And I thought all the talk of Stoner whining was dull, boring and, drawn out...sweet fuck, shoot me.

Here's some actual truth and a relevant fact

@BSMotoGP: Random #MotoGP stat of the day! 2012 was the first season since 06 in which the rider with the most wins didn't claim the championship

Older news, but Dovi has a tweaked neck and can't do any testing on the Ducati. Sounds like he found his stoner-esque "mystery illness".

That didn't stop him from winning the Simoncelli Benefit Supermoto race on Sunday in Latina Italy, beating a certain V. Rossi and Rossi's new twitter 'friend,' Max Biaggi in the process.

I didn't say it was a real issue, just that it kept him from extensive testing of the Ducati

+10000. My thoughts exactly.

Anyone know what kind of oil they use in motogp?

The Italians use Olive oil.

But you gotta know that all the MotoGP riders are reading this thread to figure out how to go faster. "Slide the front end...no, slide the back end.....no, brake with the front and slide the rear......"

I can see DP at home huddled over his computer, jotting down notes from the ADV experts...

I understand that some folks here are giving up on this easy stuff and will be moving on to NASA to instruct on how to exceed the speed of light.

This is going to be one long-ass winter without actual racing to watch........

Log into your MotoGP.com account pick any year and rewatch all of the races from that year. Maybe the 03 125 championship when Lorenzo, Pedrosa and Stoner all raced together?
Go back and watch a season of any class and year and watch all of the battles.

I just grabbed the Apple TV with XBMC and Nuvi-X. Good stuff and found a Red Bull channel with all their programming including ever Red Bull Rookie Cup race on Demand. More places to find racing.. There are BBC and Eurosport channels but haven't seen any racing on BBC yet and Eurosport isn't working yet. So far I think every program you can imagine that was ever shown is most likely stored on the Internet without commercials.

I think it's only logical they are sliding both ends of the bike...

When does a tire produce the most grip?

When it has a slight slip angle.

A top racer is going to be working both ends of the bike to 100% of the available traction lap after lap. On corner entry it's going to be trail braking and tipping the bike in with the front slipping, and exit is going to be the rear end sliding a bit as the bike stands up.

From a lap time standpoint allot of what separates the good from the amazing is how quickly and consistently they can get the tire to peak grip (which is slightly sliding) with out overshooting it and how well they can keep it at peak grip.

There's a big difference in appearance of a tire sliding at a 5% slip angle and a 15% slip angle. A 5% is barely if not in-perceptible to an outside observer, but the rider (or driver cause it applies equally to cars) can feel it and the data logging would show it.
