Hello, my name is Luiz Direito and I am from Brazil, since I Know myself I love motorcycles and sport riding .The dream of my life ever was to ride a bike in the track and I already did that 3 times and love it. Since I was a Teen age I have studied a lot about riding techniches, but only about some years could aply it in the track and learned a lot.
Pleasure to be here and share the experience with all of you.
Thanks.
Hi Luiz, and welcome!
What tracks do you ride at? We had been down to Brazil, and rode a few tracks: the track and Rio (Nelson Piquet, and one in Curitiba--don't recall the name of that one).
Best,

Hi All,
Passed my test last May, and have been riding all last summer and for a month or so this year.
I am attending the April 23rd day at Silverstone, but as the day aproaches am getting a bit nervous, which feels a bit silly as I 38 FFS!
I will be using my own bike (a 2000 Fazer 600)
I suppose this is normal?
Concerns are;
Will i go too slow?
Will i pick it up / improve throughout the day?
Will i look silly ?
Will i do stupid things like stall ?
LOL....honestly i feel like i am taking my driving test again
PS also booked the Level 2 for 17th May at Silverstone!
Hi Djm,
Mate, if you weren't a little nervous, you'd be a cyborg! As for the rest (being slow and learing), not to worry, as Bullet pointed out, a little willing to learn some new stuff attitude and you will do very well.
I guess we'll have to work on Bullet and his clutch skills though
Best,
Cobie

When watching the race, it did look like he'd crashed reasonably early in that turn, so you'd expect it was a very good candidate for trailbraking in that caused it, however, there wasn't good enough video replays to know one way or other other.
Bullet
I don't understand where you guy saw this... the only coverage available here (US) was on the MotoGP website but their coverage didn't have the crash. It was really annoying but I just figured they didn't get any video of it?
Did you see the race on Speed? It was on Sunday.

Just a bit of trivia regarding grip:
2) Grippy race track asphalt can allow up to 1.2 G of braking/acceleration
3) Normal asphalt in good condition allows around 0.9 G
I'll call a fault on that "trivia" - we have a braking force (deaccelleration) measurement box* and we see just under 1.0G on normal asphalt (heck, we just saw a 'Busa do 10.1m/s^2 on average, which is >1.0G this weekend).
Cheers,
Kai
Cool to know. I'm assuming the bigger/longer bikes (Busa, ZX-14) have excellent braking numbers/distances, due to longer wheelbase and weight--any data on that, say compared to a 600?

Hi Federico,
Bullet is a nice guy, but can't spell.
The rest of us are a bunch of bastards!
I would love to go to Spain and ride, been many years since I worked in Mallorca, and didn't do any riding

Isn't the Superbike school associated with a wheelie school, I believe in Las Vegas?
Not for some years. Keith originally invented (with an engineer's help) the devices that were used to train guys to wheelie. Then the school was sold, and it's not up and running any more.

Stoner is quoting it in all the media stuff as a description of his crash Cobie. I saw it on crash.net myself.
http://www.crash.net/motogp/news/158653/1/...atar_crash.html
Bullet
OK--this got my interest, and I shot Keith a note on this, here is his comment:
But he didn't mention if he was on the brakes or not, just that there wasn't enough weight on the front. From what Rossi says, the Bridgestones need a lot of weight on them so perhaps he didn't have the bike set up to transfer the weight forward enough to maintain his braking, if he was braking. Stoner's comment brings up more questions than it answers. KC
-
If the front is too light, it can slide (Keith covers this in Twist 2). Not letting it move back and forth as needed, can also make it slide.
Where did you find this quote?

Harnois made some good points.
C/steering is the way to get the bike turned aggressively, and push/pull can work well.

Brakding and downshifting is a good skill to have, for sure can be mastered with some practice. More info on that in the books. Here is one pointer: do the lion's share of the braking first, then the engine doesn't have to be blipped as high (and it's loads easier on the machine).
Keep us posted on how it goes!

Started as a "dirty one" I like that! Love riding in the dirt, do it very rarely
.Thanks for all that information, very interesting--I think I should start asking others to do that when they come onto the forum.
Glad to hear the boys in Greece are looking after you! Please keep posting, tell us a bit more: are track days very popular in Greece, or is there a lot of mad riding on the roads?
Best,
Cobie

Hi Costas, and welcome,
Tell us a little about yourself and the track in Greece!

Hi Allison,
You have already been welcomed, so I'll just do +1 to that.
Lyle also gave a good comment on your bike vs our bike. The 1000's are amazing, and nice to ride, but if you would get to a school sooner riding your own, then do that.
The books and DVD's are great resources, let us know how it goes with those, any comments or parts of your riding that you had some success using the info, we love to hear about it.
Done a lot of riding at Loudon, but never made it up to Maine, hope to at some point.
Best,
Cobie

Do you think those leathers make my ass look fat?
Do you want an honest answer
Of course not.

Ok. You've answered the question that I asked. But it wasn't exactly what was on my mind. I'll try this.
When going through a left / right esses or schicane, can it be useful to flick the bike around the first part of the turn to get a straighter line or exit through the second apex?
Either way, what is it that we do in that kind of situation to 'flick the bike'?
As I see it, I'm not just using counter steering while changing from left to right, I'm deliberately trying to move the wheels?
Muppett
Regarding flicking, turning quickly, esses are a great place to do this. Not sure we could make a blanket statement on the rest of your question regarding straighter line, that would depend on a few things: first turn radius, compared to 2nd, straight after the 2nd turn, etc.

Hello Cornering Experts,
I saw a high side crash on YouTube.com and it looked to me (and I don't know diddly about sliding a motorcycle) like the rider slid the rear tire, then chopped the throttle and turned into the slide. From "Twist II," this would be a perfectly natural--but wrong--thing to do. Am I seeing this correctly? You guys see and do a lot more of this stuff than I do. What do you think? The slide and high side happen at about 5:30 into the video. Thanks.

Thanks,

It's pretty hard for me to see exactly what the girl did with her throttle hand. The thing that brought the slide on in the first place was she added lean angle and throttle at the same time--she had actually been leaned over more earlier in the turn, but then she added the 2 at the same time--deadly.
-
Perhaps I didn't get it, but yes, I clearly understood that I could better make out the thumb when it was moving than static.
When I was in Marine Corps marksmanship training, I learned that the human eye cannot focus on 2 objects at varying distances with sharp focus simultaneously. As the thumb experiment above, this applies to a static target and hopefully static gun sights (LOL).
When we ride, NOTHING is static except for our view of the tank, windscreen, gauge cluster, etc. So if we're looking at these things, it is not possible to also have the eye/brain process the view of the road ahead.
Focus your attention on the patch of dirt and the moving objects blur.
So, Cobie...spill the beans man. What's the new concepts on vision?
Vision...this really is one of the big issues in riding. I think the Level 2 material is the most often re-viewed, clarified, learned again (at a great pace, the game changes), of all our material. New concepts---not sure what we have that would be dramtically new to you JB, but one can tell exactly what a rider is looking at and where his attention is going by riding behind.
Ever see a rider go through a turn/series of turns, not going really fast, and then gas it hard when comes out? You can tell the exact moment that he looks up and gets more space!

OK, I'll keep posting. Here is some worthless info: we are having the floor in the in the Student Services trailer re-finished--or at least supposed to get done, the re-finisher is late!

Hurray! Glad you're going to keep the thread going, I like it, too, nice to know what's going on.
Hey, you're in color again, nice photo!
Do you think those leathers make my ass look fat?

YNOT,
You have a few points, but the first one is you refer to "maintain throttle"--what do you mean by that, do you already have some throttle on before you turned the bike?
Lets start there.
CF
Ok ~ you got me thinking about this and I had to revise my answer.
In most corners: ie .T1 at T'Bolt
Close throttle, brake, release brake, quick turn, NO throttle. Bike is at corner entry speed, rolling, leaning, scrubbing off speed.
No, I don't trailbrake yet. I have to take levels 3 & 4. [my plug]
At full lean, start rolling on the throttle.
T2 and T3 at T'Bolt
Roll off throttle slightly to load front, not close completely, quick turn, hold throttle.
OK, that makes more sense. Some people talk about waiting for the apex before they get back to rolling the throtltte on. In many turns, one can get the throttle cracked back on well before the apex (apex as being the point the rider gets closest to the inside).

Pushing the bike under you will create excess lean angle, reducing traction and ground clearance. So for anything above parking lot speeds pushing the bike under you to steer is a pretty bad idea.
However, it can be useful at slower speeds when you want to create excess lean angle to get the bike to turn a tighter radius, like doing a u-turn in a confined space.
Also when the bars are away from you (when the bike is pushed under) there isn't as much leverage--like one had to turn quickly in one direction, then back in another. Happened to me when a car pulled out in front of me and then stopped. Quick turn to the right, then another to the left, to miss the curb on the opposite corner.
With dirt bikes the speed is also usually a bit slower, and less mass to move--a lot less in just about every case.
Make sense to you Muppett?

The no brake rule is a required part of police driver training. They have to run those old Crown Vics around the twisty track using only "stearing Breaking". This makes them concentrate on entry points and being "smooth", and smooth = speed.
Yeah, had a friend that did a lot of training, and the big cars can't take that much braking anyway!

I'm awaiting an update from Whitney
Hopefully, I'll be able to get at least 1 day in.... until that pesky virus pops up on her laptop again
heheh, know what you mean about those virus, my wife gets them now and again

Two--yep, think that bike will be more fun on the track than the street...but you've got the 1300!
See you in June.

There is some info on this in Twist 2 on this, anyone know where it is?
