I believe that most race cars with traction control also use the brakes. Anything else, ignition retard, fuel kill,
would unsettle the suspension on a bike.
Actually I spoke to the head telemetry guy as well as the team manager for the Kawasaki GP team about traction control on the GP bikes and they never mentioned using the rear brake. Retard the ignition and closing the butterflies is their main tools. I am sure that Liam has more insite into this. It also seems to be the use of a LOT of sensors that check a lot of things on the bike. They said the goal is to try to let the rider ride with the throttle wide open as much as possible. sweettttt:teeth
 
Back in BCN, maybe for a whole week!

I'm back in BCN after a week in Brno, Republica Czecha. Very nice place with very different attitudes and culture. You can tell that it's still part of the Eastern Bloc, and I will go into that in more detail in the future. My hands are quite tired and sore so I'm not going to be typing for at least a day, but there was a lot of good stuff going on during the race week, and also during the Monday test after the race. Some teams even stuck around to test on Tuesday, but there was rain. I really want to get about uploading all the photos I took in California, and Brno, but for the most part, I think you guys are waiting to see things like this.

Spotted in Brno

I thought we beat this traction control thing to death a couple months ago on this thread. There is no ABS allowed in MotoGP, and thusly, there is no braking control exerted as part of the electronic traction control system on these bikes. The brakes go like this - master cylinder, pressure sensor (braking force), caliper. There are quick disconnects for the calipers (sweet!) and ultra-trick heat sensitive paint is used on the carbon rotors to measure the heat range they are seeing. That's about it. Simple stuff :laughing. I think everyone is misreading the sarcasm from a couple people.

I spotted this shirt in Brno. No, it's not mine.

Liam, what is your thoughts on TC on the 800's for next season? Will it be needed as much as the current 990's, or will the factories drop it allowing the riders to be more in control of the exits on less powered bikes?

If they do remove the TC, could this have an effect on the 250 riders doing so well on the big bikes?
 
I'm guessing that traction control is going to be needed more on the 800cc bikes than on the 1000cc bikes. The reason for this is because they are going to have a much smaller power band in order to get maximum power for top speeds which will make the engines much peakier (and more like the old 2-strokes).

Very good point.
 
Ye, that's what I am hoping for :) Remove traction control and let the high sides begin! Bring it back to a rider racing and not the bike doing the work.

Nice question!

I think TC will be much more important, because the real trick is being able to get on the gas sooner than the rest of the pack . . . . but moreso (and not really noticed by the media/press), I think getting into the corners is critical. Let's face it, physics is limiting how fast a bike can accelerate on the straight anyway, so virtually all the bikes are at the same level there. Cranked over on the side is a different story, but every manufacturer (and to an extent, the rider) runs a different fly-by-wire system. What I mean is that some bikes are set up with a throttle that can be opened up (way up) with the bike on the side while the TC system limits how much of the throttle bodies are actually opened, and on some bikes there is a much more direct relation between throttle position and throttle body opening. Does that make sense? O.K., to give an example without saying too much, let's just say that you can whack it open on some bikes in the corner, and you'll accelerate smoothly on out, but on others if you whack it open, you're going to be on the ground.

Back to the original questions, I think the TC will be more important because on the higher strung engines, you'll need more assistance to accelerate at the maximum with the minimum of wheelspin. It's already like this, but it's going to be worse (better?) next season. Oh, what I was saying earlier - most people miss that getting into a corner is just as important as getting out. Being able to transition from full gas to full braking without a few tenths of a second to let the bike settle is going to be critical, and corner speed is going to be a key factor in the 800's. We all know the Ducati has the most powerful and agressive engine on the grid, but ever wonder why their tires seem to last longer than the Suzi or Kawi Bridgestones? Could it be the higher corner speeds of those bikes . . . ? The tire wars are going to be a huge factor in next year's bike's performance, and so far it's looking like it's going to be a good battle. Don't get caught up thinking that the 800's are less powerful than the current bikes, and also, don't worry about top speeds, either :)
Would you believe that it's possible the 800's are revving higher than the 500 two strokes?

Bah, so much speculation, and so much of the silly season is dominating the paddock talk now. Everyone is scrambling to find a berth for next season, myself included, although I recently got an "upgrade" to my position - see it here

And as for the way the new 800's sound? When I get around to it, we'll have some good stuff, better than what's out there . . . . for now, it's like this.

WaHoo!
Assistant AND official tester!

Go get 'em Liam!

Nice team shot, you look very happy to be there:teeth So what is it that your now officially testing? Bikes? Tires? Coffee machine?
 
What's a mechanic like me get to do today?

So Monday has come and gone and I haven't made it to Valencia yet to check out the kids trying out for the Red Bull MotoGP Academy. WTF? I had planned to take the early train out of BCN this morning, but at the last minute I got a phone call from the team saying I should stay close to the house because my tickets for all the fly-away races were going to be hand-delivered. Rats! On top of that, I am still trying to make sure everything will be ok while I'm out of town for another month (having been away from my apt for about five weeks - from Sachsenring through the Brno race!). To complicate things, while doing my laundry in preparation for the fly-aways, the machine broke, mid-cycle. I thought it might somehow fix itself. . . . . but then, I forgot this is Spain. Nothing is ever easy here, haha. So, I got out some of my hand-tools and went to town dismantling as much as I could, and getting water and soap everywhere in the process. It felt great - like I was on Home Improvement or something.

And no. No chance to even see the new '07 dirt models. They don't really carry them in the stores here in the city center, and I'm busy riding everyday because I know I'll be eating at hotels, airports, and restaurants for the next month.

I wish it was a mechanical failure, but it turned out to be an electrical problem with something on the circuit board. Argh! Nothing I can do to rectify this now, so I'm stuck with a pile of moldy, wet laundry.
