thnx for all of ur concern...
da incident was all my fault due to the overshot...
then makan divider tengah...
nasib baik x makan tiang lampu + sign board tu skali...
sori r kat han_JKR...
kat zul_cbr....
jaga ko jap lg...

hmmm....
thats very dangerous....
hope you guys more be carefully next time....
make some safe ride....
cornering has a different feeling....
but that can be danger if you guys "overdos"...

- GWS , fellas.

- kawan ada soalan sikit. Jika masuk corner "terlalu"
laju , apakah tindakan yang sepatutnya diambil oleh rider?
Eg , jalan yang kita tak familiar sangat , bawak masuk
corner dan nampak corner terlalu "ketat" ..

- ie , kita sepatutnya lean sampai clear corner, or lean
and brake , or straighten up and brake or macam mana tu ?

- dari pengalaman sedikit yang aku ada , semakin "ketat"
corner tu , semakin banyak yang kita perlu lean. Tapi ada
maksimum sebelum hukum-hukum physics akan apply ...

thanks.

otai2 tolong la jawab........

Bro, kalau rajin u masuk kat sini.. http://www.msportbike.com/

Kat situ ada banyak info. Ada komen by armand regarding your question. To make it short...as long as you are on rubber, you'll be surprised that the bike can still be on the road at extreme lean angle.

Another very good info was on Counter Steering, try to google on that.

betul tu, counter steering - memang besh

Well, for those who loves to go exploring the unknown roads. Here's what you should do. Always enter a corner late instead of early. So that you can anticipated what's infront of you and won't get surprise and end in a bad situation and when you are riding on roads that you are not known to. Don't go at speed which you couldn't handle your bike proper. Take it slowly, it wouldn't hurt. Besides, you are not in a circuit. So why do you need to take up a racing line?

And for Pistole Q's on what you should do. Well, this is mainly for racing but it helps in emergency situation such as having too wide of a turning radius. Try to use your brakes but by applying it smoothly and slowly. This would require frequent training since people would react into PANIC when such things happen. Give it a try by just applying the rear brakes while you're cornering (Of course, don't corner so low lah, just training mah), you will notice that the angle of trajectory to exit a corner has been sharpened. Compare to if you are using your front brake. That' not all, when I mention applying the brakes, you would need to apply more on the rear and less in front so that your bike woudn't understeer and make situation worse. Don't apply too much though since your contact patch will get lesser the lower you go. But please don't just save this into your brain and not learning it physically. You need to get used to it and fight with the fear of having to brake when cornering. Just like a pilot. Experience. Training training and training.

I guess I would need to create a 101 Topic here so that people can refer to it.

saya pernah hadapi situasi yg bro pistole bagitau tu...

ada satu soalan tentang tempat yg kita unfamiliar nih..apabila kita corner dan overshoot (makan jalan sebelah), semasa corner pulak ternampak ada kereta menghala ke kita (of course opposite direction kan!), APA YG KITA BUAT? apply counter steer??? counter steer hanya sesuai utk high speed corner dan corner2 yang panjang. kalau jalan pendek @ "ketat" confirm tak sempat beb!

jadi apa yg selalunya fast-action yg kita buat? mesti kita akan bangun balik dari corner dan halakan motor ke sebelah "sana"...dan jugak brek mengejut...slalunya 'brek mengejut' yg buat kita jatuh. dan itu lah yg berlaku kat saya!

cheers.

- itu yang paling menakutkan , pasal memang pernah berlaku
pada masa riding kat jalan menuju ke Gunung Pulai.

- beberapa kali tu , saya lean (dan 1/4 throttle) , tapi macam
mana lean pun , bike semakin me-lebar (ie , going WIDE), sampai
floorboards touchdown (terkejut !). Janji bike sudah sampai ke
jalan seberang ..... ngeri terpikir aku sekiranya ada lori coming
dari arah bertentangan .. don't think aku akan ada masa untuk
elak ....

.

Maybe that's how a Harley works?

Ecik, rides a gold wing, I'm sure those kind of bikes are not meant for high speed cornering but high speed chroming.

Anyway, who's coming tonight? Pistole, you free for tonight's meet? I'm kinda missing the meet here, last week didn't participate. So very gatal already.

so, kesimpulan bagi saya sekarang, setiap unfamiliar route, jangan la mau tunjuk itu skill riding macam rossi....
dan bagi tempat yang sudah familiar pun, kena pastikan condition tayar cun + sudah cukup panas dan brek berfungsi dgn baik, plus condition jalan pun CUN means tak ada pasir2, minyak gris, basah bla..bla..bla...

kalau tak,
nanti jadi mcm ini,


bila dah jatuh, badan sakit, hati sakit, motor sakit...


ini jalan "ketat" yang saya fahamkan. dapat lihat satu corner agak luas dan satu lagi corner pendek + BERPASIR!

macam moto seludup...tu pasai terbarai cenggitu...ni mesti nak mengelak kena angkut naik COURT !!

but u guys....ride & drive berhemah....tyme slow u must slow...tyme speed u MUST speed
kalu ride or drive kat heway kalu x speed 180km/h to 220km/h jangan nak try guna lane kanan (nasihat dari PENAJA utk DITAJA)

abis tue aku selalu guna lane kanan....
tapi mtr aku x la laju sampai 200 kmj....
boleh jer kat lane kanan....
mcm ner plak tue erk cikon....

The answer to this, beside counter steering you should apply trail braking.

Counter steering, I rasa semua sport bikers dah tahu dah...
Trail braking ni... emmm susah nak explain dalam bentuk writing, tapi you all can google for it.
Learn and try to practice (aku practice kat PG Trek). Memang berkesan sewaktu aku overtake kereta dan masuk tight turn.

Bestkan, aku pun dah tertagih ngan Trail Braking. Kadang-kadang overshot tapi dapat dikawal ngan baik.

Someone asked: “What is Trail-Braking and how is it done?”

Most seasoned sportbike riders probably already do it, but just don’t know it. If you’ve ever over-cooked a turn, you also probably trail-braked. Mastering trail-braking is also mastering the fine line between crashing and staying vertical.

In a perfect turn (read: as fast as possible without losing tire grip), you are either on the gas or on the brakes. NO COASTING! Its actually a helluva lot harder than it sounds. The reality is that trail-braking maximizes your corner entry and exit speed to a lesser extent.

There is a rule of thumb that is taught in driving schools: You only have 100% of available grip and that is to be shared between the cornering & braking and cornering & acceleration. Add braking and you have to reduce your cornering. Add acceleration and the same is true. Add cornering, and you again have to reduce braking or acceleration.

I went through Bondurant’s GP Race school on the company tit…well just because its required. They taught us to imagine (in a car of course) that the bottom center of the steering wheel was connected to your right foot with a string. Regardless if your foot is on the gas or the brake pedal, if you turn the wheel, the string pulls up on your foot proportional to the amount you turn. The more you turn, the more your foot gets lifted. Make sense?

This same theory applies to bikes. While you are taught to brake in a straight line (do all the braking completely vertical), a skilled rider can learn to brake later into the approach and actually carry light braking throughout the turn. The important word though is LIGHT. If you could brake heavily while leaned over, the MotoGP riders would never stand the bike up and choose an upright entry into the gravel. Too much braking leaned over will result in a low-side.

If you disect a turn, you really have only three components: entry, apex, and exit. On a normal ride all of the braking is done upright before the turn, coast through the apex leaned over, then roll on the throttle as you exit. On a perfect ‘race’ turn, you brake until the apex area (depending on the features of the turn) then immediately roll on the throttle as the brake is being released. Most mortals who ride well through the mountains tend to fall in the middle of no versus perfect trail-braking.

As to what does it take to get good at it? A track day is the best option with the wide lanes, braking markers, and room to play without oncoming traffic. If you must learn on the street, practice on a stretch of twisties that is empty as well as using baby-step increments. Note where in the turn you release the brakes and where in that same turn you roll on the throttle. All that coasting time in the middle adds up to longer lap times at the track. I wouldn’t use the rear brake at all until you are very familiar with the method and are going insanely deep into the turns. I do on occasion use the rear brake when trail-braking, but ever so slightly and only due to an operator error that I am trying to recover.

I will say that trail-braking makes the turn much smoother as you only have one suspension transition. On the track, its where you can overtake a lot of riders by going deeper into the turn. Next time you watch the races, pay attention to the clip-on camera angle and look at the time between the brake lever release and throttle roll-on…its minimal.

I will also say that planned trail-braking leaves no room for error, especially on the street. I learned it on the track (car & bike) and was able to apply it to the street. It works, but not without an associated risk.
