BUt I thought it is just too good an article to not bring to the fore again, and again, and again:

Current for all, free info for all, :

Maybe! Maybe? a post box/Thread title/ called- Biker recurrent training and Education::

This is the article::yes::yes:

Braking in a corner - from Nick Ienatsch

I have posted this before, for the OP and others that may not have seen it..... IMO it is a long, but good read.

Cheers!

*************************************************


"If you have to stop in a corner, one of two things will happen. One, you will stand the bike up and ride it off the shoulder and into whatever is over there. Or two, you will lay the bike down and slide off the shoulder of the road. Braking is done before, or after a corner. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind."

Hiya FZ1 lovers.
I’ve stewed for two days about the above quote taken from another FZ1OA thread...and finally decided to launch this thread. In past years I would have just rolled my eyes and muttered, “Whatever”…but not anymore. I want to tell you that there are measureable, explainable, repeatable, do-able reasons that make great riders great. And brake usage is at the very tippity-top of these reasons. It’ll save your life, it’ll make you a champion. It will save and grow our sport.
I’ll ask this one favor: Would you open your mind to what I’m about to write, then go out and mess around with it?
To begin: Realize that great motorcycle riding is more subtle in its inputs than most of us imagine. I bet you are moving your hand too quickly with initial throttle and brakes. Moving your right foot too quickly with initial rear brake. The difference between a lap record and a highside is minute, almost-immeasureable differences in throttle and lean angle. The difference between hitting the Camaro in your lane and missing it by a foot is the little things a rider can do with speed control at lean angle. Brakes at lean angle. Brakes in a corner.
Yes, a rider can brake in a corner. Yes. For sure. Guaranteed. I promise. Happens all the time. I do it on every ride, track or street. Yes, a rider can stop in a corner. In fact, any student who rides with the Yamaha Champions Riding School will tell you it’s possible. Complete stop, mid-corner…no drama. Newbies and experts alike.
There are some interesting processes to this sport, mostly revolving around racing. But as I thought about this thread, putting numbers on each thought made more sense because explaining these concepts relies on busting some myths and refining your inputs. Some things must be ingrained…like #1 below.

1)You never, ever, never stab at the brakes. Understand a tire’s grip this way: Front grip is divided between lean angle points and brake points, rear grip is lean angle points and acceleration points, lean angle points and brake points. Realize that the tire will take a great load, but it won’t take a sudden load…and so you practice this smooth loading at every moment in/on every vehicle. If you stab the brakes (um...or throttle...) in your pickup, you berate yourself because you know that the stab, at lean angle on your motorcycle (and bicycle, btw), will be a crash.

2)Let’s examine tire grip. If you’re leaned over at 95% (95 points in my book Sport Riding Techniques and fastersafer.com) of the tires’ available grip, you still have 5% of that grip available for braking (or accelerating). But maybe you only have 3%!!! You find out because you always add braking “points” in a smooth, linear manner. As the front tire reaches its limit, it will squirm and warn you…if that limit is reached in a linear manner.
It’s the grabbing of 30 points that hurts anyone leaned over more than 70 points. If you ride slowly with no lean angle, you will begin to believe that aggressiveness and grabbing the front brake lever is okay…and it is…until you carry more lean angle (or it’s raining, or you’re on a dirt road or your tire’s cold…pick your excuse). Do you have a new rider in your life? Get them thinking of never, ever, never grabbing the brakes. Throttle too…

3)If you STAB the front brake at lean angle, one of two things will happen. If the grip is good, the fork will collapse and the bike will stand up and run wide. If the grip is not-so-good, the front tire will lock and slide. The italicized advice at the beginning was written by a rider who aggressively goes after the front brake lever. His bike always stands up or lowsides. He’s inputting brake force too aggressively, too quickly...he isn't smoothly loading the fork springs or loading the tire. He may not believe this, but the tire will handle the load he wants, but the load must be fed-in more smoothly…and his experience leads to written advice that will hurt/kill other riders. “Never touch the brakes at lean angle?” Wrong. “Never grab the brakes at lean angle?” Right!
But what about the racers on TV who lose the front in the braking zone? Pay attention to when they lose grip. If it’s immediately, it’s because they stabbed the brake at lean angle. If it’s late in the braking zone, it’s because they finally exceeded 100 points of grip deep in the braking zone…if you’re adding lean angle, you’ve got to be “trailing off” the brakes as the tire nears its limit.

4) Radius equals MPH. Realize that speed affects the bike’s radius at a given lean angle. If the corner is tighter than expected, continue to bring your speed down. What’s the best way to bring your speed down? Roll off the throttle and hope you slow down? Or roll off the throttle and squeeze on a little brake? Please don’t answer off the top of your head…answer after you’ve experimented in the real world.
Do this: Ride in a circle in a parking lot at a given lean angle. That’s your radius. Run a circle or two and then slowly sneak on more throttle at the same lean angle and watch what your radius does. Now ride in the circle again, and roll off the throttle…at the same lean angle. You are learning Radius equals MPH. You are learning what throttle and off-throttle does to your radius through steering geometry changes and speed changes. You are learning something on your own, rather than asking for advice on subjects that affect your health and life. (You will also learn why I get so upset when new riders are told to push on the inside bar and pick up the throttle if they get in the corner too fast. Exactly the opposite of what the best riders do. But don’t believe me…try it.)
Let me rant for a moment: Almost every bit of riding advice works when the pace is low and the grip is high. It’s when the corner tightens or the sleet falls or the lap record is within reach…then everything counts.
“Get all your braking done before the turn,” is good riding advice. But what if you don’t? What if the corner goes the other way and is tighter and there’s gravel? It’s then that you don’t need advice, you need riding technique. Theory goes out the window and if you don’t perform the exact action, you will be lying in the dirt, or worse. Know that these techniques are not only understandable, but do-able by you. Yes you! I’m motivated to motivate you due to what I’ve seen working at Freddie’s school and now the Champ school…
I’m telling you this: If you can smoothly, gently pick-up your front brake lever and load the tire, you can brake at any lean angle on and FZ1. Why? Because our footpegs drag before our tires lose grip when things are warm and dry. It might be only 3 points, but missing the bus bumper by a foot is still missing the bumper! If it’s raining, you simply take these same actions and reduce them…you can still mix lean angle and brake pressure, but with considerably less of each. Rainy and cold? Lower still, but still combine-able.

5)So you’re into a right-hand corner and you must stop your bike for whatever reason. You close the throttle and sneak on the brakes lightly, balancing lean angle points against brake points. As you slow down, your radius continues to tighten. You don’t want to run off the inside of the corner, so you take away lean angle. What can you do with the brakes when you take away lean angle? Yes! Squeeze more. Stay with it and you will stop your bike mid-corner completely upright. No drama. But don’t just believe me…go prove it to yourself.

6)Let’s examine the final sentence in the italicized quote. The best thing to do before taking a corner is to grind the thought "I'm going to turn this corner" into your mind.
No, that’s not the best thing. It’s not the worst thing and I’m all for positive thinking, but we all need to see the difference between riding advice and riding techniques. This advice works until you enter a corner truly beyond your mental, physical or mechanical limits. I would change this to: The best thing to do before taking a corner is to scan with your eyes, use your brakes until you’re happy with your speed and direction, sneak open your throttle to maintain your chosen speed and radius, don’t accelerate until you can see your exit and can take away lean angle.
7)Do you think I’m being over-dramatic by claiming this will save our sport? Are we crashing because we’re going too slowly in the corners or too fast? Yes, too fast. What component reduces speed? Brakes. What component calms your brain? Brakes. What component, when massaged skillfully, helps the bike turn? Brakes. If riders are being told that they can’t use the brakes at lean angle, you begin to see the reason for my drama level. When I have a new rider in my life, my third priority is to have them, “Turn into the corner with the brake-light on.”

I’ve said it before: This is the only bike forum I’m a member of. I like it, I like the peeps, I like the info, I love the bike. Could we begin to change the information we pass along regarding brakes and lean angle? Could we control our sport by actually controlling our motorcycles? If we don’t control our sport, someone else will try. Closed throttle, no brakes is “out of the controls”. Get out there and master the brakes.
Thanks, I feel better.

Tf125 no spark

Have a 90s tf125 no spark. Had been sitting a few years started up second kick came back to it the next day and it ran very rough so changed plug then no spark at all. Tested stator and cdi and coil coil had nothing running through it so replaced with one off a working bike but still no spark have gotten another cdi will put on. Could it be that the magneto has shit itself from sitting to long and is not putting out the right amperage cheers.

Scooters Are Hard (er) To Ride In A Test

I had a chap yesterday arrive to do his Basic Handling Skills Test with his own 150cc scooter. CVT transmission. That's an auto transmission.

He thought it would be easier than riding our GN125 as there was no need to change gears. Well I can tell you, CVT transmissions have challenges of their own, and the BHST is no doddle on a CVT bike.

When you throttle on, there's a slight lag, as the CVT winds itself up and gets going. When it does, especially on bigger bikes, it takes off quite quickly. At the other end of the scale, when you throttle off, there's significantly less deceleration, so the brakes get far more use. Basically, your throttle control needs to be better on a CVT bike than a GN, as the GN is seasier to maintain constant progress on, without accelerating or decelerating.

Add to this the smaller wheels, and they tip into corners more quickly. The one yesterday had less lean angle than a GN as well.

Don't get me wrong, I like CVT bikes. I rode the one yesterday, and it wasn't hard to ride. I rode the course and stages on the bike yesterday, and It's quite a cool bike. But it has it's own set of challenges.

Just don't go thinking it's easy to do a test on an auto bike. It's not hard, it's just different. But it's also not easy.

It Won't Happen To Me, I don't need to change.

Sickening.

Certainly I make no reference to those have departed in the recent days and distant past. I post this in the (potentially vain) hope that it might open some eyes.

Paper Article (1).jpg

As a society we live with the belief that "it won't happen to me."

Often this belief is reinforced by the lack of adverse outcome, which teaches us, subconsciously, that whatever we have done is safe.

For example, I'm driving home from work, my phone sitting face up on the passengers seat. The phone rings, I look down, and there on the screen of the phone is a picture of my wife peering back at me. It's my wife calling. Several things go through my mind; if I answer that, I might get a ticket, I might kill someone (the ads say so), I might run over a child. All adverse outcomes. Then I realise that not answering a call from my wife carries a greater adverse outcome, so answer, quickly dispose of the call, and put the phone back down. Result? No adverse outcome. I've subconsciously reinforced the belief that what I did is safe.

The next time the phone rings, It's just that little bit easier to answer, based on my previous experience. After 400 calls, I'll be snap chatting, instagramming, facebooking, updating my work calendar.........you get the idea.

Same with other, motorcycle related behaviours. Those who don't wear gloves, and haven't for years, won't, because it's not going to happen to them. They are a good rider, riding for 30 years, never had a crash (that they will admit to), it won't happen to them. They don't need safety gear, it's not going to happen to them. No, this is not a rant about safety gear, this was just an example of historically reinforced risk behaviour.

But each day in NZ it happens to someone. I've attended thousands of crashes over the years, and if I had asked each driver involved if they knew their crash was going to happen, of course they would have said no. Because of they knew it was going to happen, they would have prevented it.

We don't know when it's going to happen to us, because if we knew that, we'd prevent it. We just don't think it'll happen to us.

We see no reason to maintain good following distances, as we've been following too close behind our riding mates for years, with no adverse outcome. Nobody can tell us to maintain a legal or better following distance. We've been lane splitting for years, legally or illegally, with no adverse outcome. Nobody can tell us it's a marginal idea. We change lanes without head checking, because we've been doing it for years and never had a problem, where's the need to change that little number?

How about we front foot stuff, and consider that however unlikely, no matter how flash a rider we are, it just might happen to us. Imagine that. We have the chance to change our outcomes. Wow, revelation.

Just a wee bit of a rant, as I've heard so much about how everything is someone else's fault. Police's fault, gubbermits fault, foreign tourists fault, white-van-man's fault. It seems everything is someone else's fault. The discussion about fault means nothing to your broken arm, broken leg or ruptured spleen. Fault means little when you are the victim of someone else's mistake, let alone your own.

And I repeat, I make no judgement regarding the crashes in the article. Poor beggars. But I bet they didn't think it was going to happen to them.
