Whaow, what a RUSH!

This is strictly for educational purposes b/c I would like to know how to power slide properly (I will practice this more on the track of course).

Let me set the premise first: This was on a one-way road. Road was completely clean of debris, and no change of elevation or bumps, and plenty of run-off space. Fully leaned and traveling at a high rate of speed. (also look at diagram below to help illustrate this)

I wasn't purposely trying to do what I'm about to describe, but at the rate of speed and the angle of lean...it just happened. What I was trying to do was widen my point of exit. My brain couldn't figure out this feeling at the time, but it was like I was floating/sliding to the right while I was leaning left. It felt like both tires were doing this. I went from the left over to the middle of this road. Then I quickly shifted my wait to the right (against the turn) to bring the bike back up as I exited the turn. CarnageR1 was somewhere behind me, I'll let him add/comment on what he saw. He later told me that it looked like I was going to low side b/c it looked like the bike was on its frame sliders. lol

Was this a power slide? If so, I want to know how to go about learning how to do it, instead of it happening unexpectedly.

This obviously happened inadvertently. Tips and advice are welcome, but please spare me the lecture of not doing this on the street. I'm aware of that! I wasn't trying to do it on purpose and I'm not going to try to practice it on the street.

I want to know is how to properly do it. Enlighten me... :)

That was you needing better tires.

I got a set of pilot powers on that are in great shape.

+ warm & sunny day

To slide the rear, just screw the throttle on while coming out of the apex, easy, just don't chop the throttle during a slide or you will be on a first name basis with the local emergency room nurses. Can you say "highside" chillun?

If you are sliding the front then you have a bigger set than mine!

I'm riding Pilot power rear and power race medium soft front.I practice turning on a desert road with great turns.I get to knee drag easily and slide the rear exiting turns is becoming easier. Small slides but the feeling is awesome!!! I guess I'll get power race on the rear too or maybe the new Pilot Power 2CT...

I may have had the back slide a bit but NEVER the front. Only seen that in MotoGP :)

Cool story! I love the diagram :lol

You answered your own question, it really depends on your rate of speed, lean angle and available grip... Once in the turn your available traction clearly wasn't enugh to support you speed and lean angle causing the tires to drift slide whatever you want to call it... Glad you were able to recover... Because once your sliding your at the tire limit! otherwise you wouldn't slide...

Sounds like you faired very well through this experience (important not to panick) because newer riders will generally chop the throttle which in your case, since both tires were sliding, would have washed out the front causing a lowside...

Anyway to slide the bike in a turn depends on the turn, your speed, your lean angle, tire grip the tire temperature (so many factors) basically you would have to do things differently for every different corner and it would never be the same...

If you look at most pictures of powerslides, its coming out of the turn, and the riders are "forcing" the bike vertical while doing this. Lean angle + throttle = loss of grip. The more lean angle, the less throttle you can use. The less lean angle, the more throttle you can use.

I doubt anybody on this forum can answer that question. Show me someone that can lay 50 foot darkie on a streetbike with blue smoke pouring off the rear tire.....

ok.....go to any exit ramp and what will you see??? long black marks let from everything (cars, trucks, semi's). How do you think tires wear down? What happens to the rubber?

Most guys ride behind someone and see black strips getting put down on the pavement. Does that mean the tire is spinning? um........NO. I could leave long darkies on my 600rr all day long, and I guarantee I wasnt spinning the tire up.

of course, you could just be messing around, but I thought to drop the info on dudes that might take that for real. Show me a video of you at that spot with the back end out 2 feet, smoke pouring off the back for 50 feet, while leaned over McCoy style and I'll paypal you $100.

where is that McCoy vid anyway? the one of him on the Kawi

Yes, I know that big vehicles do lay down rubber sometimes, but obviously that isn't the only way rubber wears down. You're right about being able to lay down darkies without spinning the tire too. It happens for me on rubber that is getting worn. The guy behind me will tell me that I was laying them down out of every corner, even 1st gear stuff, where it will wheelie before it spins. In that particular corner, that particular stripe it was spinning the tire a bit. Was it hung out nearly to lock, smoking the tire? No, hardly. Enough to change the attitude of the bike, the bars and the line? Yes. I was just posting it to mess with you though. :crash

It takes a huge amount of mid-corner speed and smooth throttle application to hang the back out. If you are getting quick jerky slides, it's because of slow speed and greedy throttle. Or you can be tight enough on the bars to cause a slide way below the real speed needed. I have had a number of smooth controlled slides on race tires (a whole other ballgame vs street rubber). Can I do it on command yet? Nope. But, I betcha if I threw a 208ZR on the back, within 5 laps around that corner, I could have it hanging out.

FWIW... In that vid it's pretty clear that he is not tkaing the fast way around. Is his bike control amazing? :yesnod

I hear ya, every time I've slid on the track its not really planned :lol I can usually manage them, but when the front pushes on corner entry I still sh*t my pants :sneaky

For me it was easy on a '03 but I just can't get it right on the '05. Not enough mid range and if I'm honest I'm bothered about the power surge at 10,500 rpm. If that suddenly comes in while cranked over and not ready for it it's highside time. On a '03 the rev and power range was such that you could enter a turn at the top end of the power allowing controlled slides. There was no sudden rush going to come and bite you. The '05 just doesn't allow you to do that.

To answer the first question though; no it wasn't a powerslide. What you had was a loss of traction to both tyres. In a powerslide the front will stay planted facing where you want to go. The rear loses traction under control as you start to exit the turn and regains traction just about when you're upright. As for hanging it out 2ft that's spectacular but not the fastest way around a turn. And admittedly I couldn't hang it out that far anyway.

give me a GP bike.

Was on a ride with a group of friends 2 years back and was introduced to a dude on a Duc 999 that used to race a while back. He frequently got on the throttle as the bike was coming out of the corner and was laying some very nice black lines behind him. Could also see the blue smoke coming from the rear,was awesome(plus that unique Ducati note made it even more sweet:cool: )

PS:For any melb guys reading this,it was Rob from MPR:bow

Get some Mettzler M-1's and warm them up... you will be able to boil them off through every turn :p

btw: M-1's suck for hard riding, but the Pilot Powers are great for it, grippy but very controllable with the tail out.

I can feel when the back slides, but I take it as a tyre/track problem or too much throttle.It's not controlled at all. It feels good, but I fear that if I continue to do it I will eventually slide too much and ... crash.
I wish I could do a lot of track days to try to figure it out.

Loosing the rear coming out of the turn is something you don't want to do. It doesn't make you any faster, less grip = slower acceleration = slow lap times. Keep trying to do this and you will end up on your ass HARD. I've seen to many people on liter bikes and even 600s at the track start to loose the rear and chop the throttle. It's a natural reaction that just happens and you can't help it.

Ideal acceleration is the fine line between spinning the rear and not. It is a FINE line. So be careful guys.

Probably hit a slick spot. puhed the front and rear, then re-gripped. Happens to me when I ride the windies when its damp. Judging by your rear tire it DEFITNELY was not a power slide. Tires tell no lies.
