panic practice is fun

I did a bunch of practice panic stops today.  I started at about 10mph and worked my way up to 35 mph.  I locked the rear tire several times.  It was fun sliding it around.  I was surprised how much more I could use the front brake.  I was shocked how long it took to stop.

Anyway, I had a lot of fun and just felt like saying that.

2-1?

Also, I googled "2 - 1 panic stops", and though I didn't find out what 2 - 1 is, I found this and thought it was a good read.  It restates in a slightly different way, a lot of good techniques that were also covered in the MSF and in Proficient Motorcycling by Hough.

and again I say:
2-1?

start maneuver in 2nd gear ( th 2, in 2-1) anyhoo in 2nc accelerate to around 20-30 ish, then hit BOTh brakes while downshifting to 1. 2-1, and braking on teh threshhold of locking up but not quite. you stop QUICKLY :thumb:

I practice occasionally from 80MPH on clean pavement.  DON'T practice multiple times in a row from that speed though, you'll end up with a warped rotor.  Ask me how I know.   :technical:
Every zero you add to the tolerance adds a zero to the price.

i always wondered how much the rotor could take. mine gets noisy (heat/pad swell) from a 65mph panic test. usually, the lower speed stuff is what i'll do. safer, easier, and steer/brake stuff means i hopefully won't flip it. :)

hmm, 2-1. your explanation is a little hard to follow but i think i got it. :)

i know i -should- be in the proper gear for whatever panic situation i'm in but this is something i'm terrible about. a 45 to zero panic brake means i may/may not be in 1st when i get there. thankfully the gs's clutch can handle a 2nd or 3rd gear panic START also.

practice stuff be-it slow speed maneuvers or just braking is a blast to me. a cool thing to try is to use a line /skid mark/whatever in a parking lot as a starting point. look straight ahead as you normally would and panic brake from that line. you'll be surprised just how long before you produce a skid mark at that line. sometimes it's 4 feet, sometimes 14. that means reaction time, perception, everything is slower than you thought ;)

1) be careful sliding the rear ! it's fun ya, but it can throw you terribly if you release at the wrong time !
2) check your pads and rotors. it should be a better than a car stopping (notice i said car, not super car like a subaru xti or lambo!) at the same speed. assuming you are using your full braking ability. the front brake has a TON of stopping power on dry/clean pavement.

Super cool.  thanks for all the great ideas!

I was doing 2-1's from 30 ish.  I think my front rotor must have seen its share of 6-1's by the PO.  Also the whole front brake assembly clunks around up there pretty good when I go off a curb.  The mounting bolts are tight, but there is still a decent amount of floating play.  Pads have ~2mm warning track left.  Ideas there?

I think the braking potential of the bike is good.  I think I have much more rider learning to do because I was shocked at how much MORE I can squeeze the front brake, and feel like I am nowhere near skidding the front or stoppie-ing.

I skidded the rear maybe 3 times.  I could feel it sliding back and forth and felt good with it.  I modded the rear pedal pressure when the rear wheel was lined up.  I didn't really think about that.  I guess I learned more on my bicycle in jr high than I thought. 

My bicycle did not teach me to use nearly that much front brake though.  A bicycle is so light that it is begging to flip me.

I had to keep reminding myself to downshift.  That is not automatic / habit yet.  I was using shadows as a "start stopping" point.  The stpeed feels so different than in a car that it is difficult for me to judge relative stopping distances.  I think the stopping is better on the bike, but I have no data to back that up.

2mm isnt much. and pads are NOT hard at all to replace. in most cases can be done in less than 10 mins
