Like a dirt tracker. Sometimes coming into an intersection two Hot, making the sharp right hander, I hit rear brake hard and slide rear around. It's a great feeling whipping the little XB around. anyone else like the "Moto GP" Slide..LOL

Your very lucky you didn't highside. Never hit the rear brake that hard in a corner. You can powerslide it, but don't use the brake or downshift. Have you read Twist of the Wrist II by Keith Code? Get yourself a copy if you have not.

Actually, it's hard braking before starting your corner turn. As the rear is sliding out, you guide it into the turn.

"twist of the wrist" are must reads..!!!

If you are doing this on an open road you're nuts - if you want to be flat-tracking it out there get on something with knobbies and on a closed circuit - I pay too much for insurance already (never an accident and no tickets - just subsidizing others' hospital bills...) and have seen enough road pizza for 3 lifetimes already...

I don't make a habit of this type of braking. Matter of fact I was very surprised when the Back wheel locked up the first time.
I to have never had a ticket or a road accident, I have been riding 30 years (i am 35 now)..and yes, i use to race motorcross and flat track.
So I do know the best place for aggresive riding is on the track

I can appreciate the fact you have 30 years on 2 wheels however some things are just best left for the track - enjoy your ride and best of luck.

Not the way you describe 60,
But I have had the rear begin to slide to the outside when accelerating hard out of corners on mountain roads before. It did surprise me the first time, I had never done that before, but a gentle slight roll off of the throttle gets things back in shape. At least that's how I've been reacting. Maybe a pro (on a track) would just power through until the rear begins to hook back up. I dunno.

It does make me wonder how people can say the 9 is underpowered, and makes me wonder if they have ever really pushed one hard.

>>>>I hit rear brake hard and slide rear around.

Be certain the payments on your medical and vehicle insurance are current.

Stabbing the rear brake, whilst heeled over, and sliding the rear of the bike, in what you think to be a controlled slide, is a function not of skill, but luck.

As with soldiers, sportsmen and fortune tellers, your's will eventually run out. The salient difference is that the stakes are higher here.

I don't see much of a point in owning a sport bike if you don't try to push the limits, at least sometimes. If your not going to accelerate Full on, Corner fast and brake hard, Why own a bike like this?

I guess if your just out posing that is your choice.

I've got a super high performance credit card with a five-digit performance limit. However, I have enough common sense not to use it to its full capabilities -- except in carefully controlled situations.

Be careful man,

I slide the rear of my Dyna around, but thats by using the gas & spinning the tire. Hitting the brakes in a corner on the street & doing that is simply asking for a highside.

Triple your life insurance asap.

Chill out guys,
Gonen enjoys sliding the back end out going hard into a corner under brakes...this is how you stop and turn fast on a dirt track...if you haven't ridden dirt you'll have no idea what he's talking about, like why is riding a good sportbike on the road so much fun? Cause it's the next best thing to riding dirt, only faster...
I saw Rossi was guilty of this same crime just last weekend. Funny how a lot of good roadracers used to ride dirt. Flames please...

At the risk of starting a discussion I don't have time for we are talking about two completely different things.

The difference is that dirt trackers do NOT locl or brake the rear wheel to get it out. If, even on pavement, you "power" the wheel out, I'd buy that scenario.

Any scenario that involves "stabbing the rear brake" is, thanks to the simple laws of physics, an invitation to trouble.

I'm not preaching how someone should or should not ride and I used to love on my KTM MX250, to whack the throttle and do the oposite full-lock power slide (which I frequently lost due to my lack of developed skills) but I'd use great caution with the technique described above.

Just my $0.02.

BTW, Rossi's not locking the rear wheel when he "backs it in". He's punchin' it down a couple gears while he's hard on the front brakes, and then instead of blipping to smooth the shift he's just letting out the clutch and the tire starts to skip and do a controlled slide as the wheel spins up the engine, then by the time he leans it over he's gassing into a power slide. He's NOT locking the rear brake, his wheel is always spinning. Not to argue anything about dirt tracker style, just commenting on his technique.

My bandit will slide the rear if I downshift from second to first and let the clutch out a little faster than usual (and yes, it is definitely a cool feeling, but normally, I'm doing this in a straight line on an empty road, just to acclimate myself to the feeling), but I definitely would not advocate locking your rear brake...too hard and you'll low side, but if the tire catches, it's a high side.

Wow, you've done that on a Bandit?
I'm impressed!
The 12 must truly be a different animal from the 6. I was never really comfortable with the suspension my Bandit offered.

Back to topic.
The only time I use the back brake is to scrub off a little speed. To lock up ANY brake is to not be in control of the bike.
Gonen:
When the wheel spins back up after the lock up, does the bike shudder when it's stands back up?

Glitch, remember I'm talking about a downshift to first, so the speeds aren't that great (say only 35 in second), and the downshift (I forget what first is geared to) is enough to break the traction...the trick is the keep the throttle smooth, or it starts getting squirrely for a bit...hence doing it in a straight line to get use to the feel incase it ever happens at speed (too old for diapers ;^D )

This is not a cornering practice I subscribe to all the time. Matter of fact it was after many times of cornering to hot, that the back wheel even locked and started to slide. I thought for the longest time the rear wheel wouldn't even lock up. The first time it happened, I was coming to a intersection, and was going to make a right hand turn. I was going a little to fast, and there was a car, that was stopped, waiting to go through the intersection, a little over the line, where I had planned on turning right. I had to apply both brakes, and was not slowing enough. the car had not left me the full lane to turn into. I had to stab the rear brake. the back tire started to lock and slide, I released the front brake and slid in a controled manner into the right hander. when I was where I wanted to be, I brought the throttle on slowly and powered out of the corner. Since then I have done it a few more times. No big deal. It's nice to know, that I can slide the bike and hold control if need be.

so the speeds aren't that great

Ya know it's kinda funny how these forums are for me....
Everything while I'm reading happens at hyperspeed...

The road was actually the end of highway 264 that dumps traffic into the Virginia beach resort area. I was going about 55 when I started to brake. So to answer your question, I was not in Hyper race mode..LOL

IMHO, I use both front and rear brakes in combonation coming into a corner but almost never "in the corner" unless I made a mistake... then goose the throttle coming out of the corner.... braking in the corner eats up the "friction budget" and takes away from lateral grip....

Must have been a combination of cold pavement and cold tire but today when I first started to ride letting the clutch out a little fast from 3-2 and 2-1 caused the rear wheel to lock and slide a little. Kinda fun but really makes you aware of whats around you and your appreciation for warmed up tires.

Reminded me of my dirt biking days sliding the rear through corners. You can get away doing that and hitting the rear brake and sliding around corners in the dirt but not a good thing on the street. Hitting the brake and sliding the rear on pavement is a good combination for a high side.

Like I said, I only do it to familiarize myself with how a loose rear end feels on the pavement. IMHO, it's totally different than on the dirt (course my dirt experience isn't a whole heck of a lot either, but that's where breaking the rear loose is really fun, public roads it presents more of a danger, especially when you do it in a turn)...

I have a short video at home that I love to watch. It's Max Biaggi on a Super Motard, just rippin' it through a go-cart track. He backs it in, slides it sideways, I think this is what was going through my mind as I read this thread. I'd love to see him on a Buell doin' this stuff. You can see it for yourself here...

You can do this relatively safely on a super mot because of a few things.
1. Weight distribution very much on the rear whell - allows better control of the slide than 52% on the front like the XB's.
2. Suspension set-up - the supermots have a much smoother and longer travel suspension - this allows a more progressive break-loose of the rear wheel than on an XB.
3. Weight - take off 100 lbs and this gets the weight down to levels where body positioning on the saddle has a much greater impact than on an XB where the center of gravity is too high with the rider.
4. Tire compound - the supermots are using track compound that is meant to slide in this manner - street tires aren't meant to do that - they are made to stick - much less progressive than a track set-up.
5. Chassis and wheelbase - the supermots have a much longer wheelbase than the XB with the tires spaced out much more vs the center of gravity - this allows for more horizontal stability in a slide than an XB. It also allows for corrections with the handlebars because the reaction to input will be more progressive and add to the stability - finally the front end is likely running a 25-28° head angle which just adds to this.

this thread pretty much sums up why it is dangerous to believe what you read on the web.
