stoppie...500lbs bike?!

Postby david_12121 » Sun Jun 02, 2013 4:14 am

I like to practice riding on the absolute limit of the tires(in empty parking lots)...helps me be more ready on the road.
So a few weeks back, doing this, I was practicing 100% stops from 35-50 mph, and one time I go a bit too far and slid the front tire! It was in the shape of a 5-7 yard black line. I kept it straight and everything was good. But I tried it again a few times, and no matter what I do it still locks the front rather than lift the rear!

So the question is, can the bike do it? Anyone done it before? Should I be heavier to be able to affect the weight balance enough?
I like being corrected! Do it!

My baby-cat is sitting at home, just chillin...I, on the other hand, enjoy the 141hp of my k3 GSXR 750 very much.
I feel guilty but it's her fault...she coulda had more powah (I'm shallow like that) ;)

It can, though the only rolling stoppie I did was unintentional. ;P

Someone on Cherohala skyway decided to to a u-turn in middle of a curve.... the guy behind me made a comment about the condition of the exhaust headers on bottom ;P

Stopping into a stoppie is a matter of last-second brake pressure on hot tires. otherwise you slide

Obviously the middle of the freeway is not a great place to do these. ANd if you have never done them before then I would recommend taking plastics off first ;P

you are probably stabbing the brake too fast and the tire doesnt have enough time to grip. The initial lever movement should be very progressive so the weight shifts to the front end and flattens out the front tire creating a bigger contact patch. The hard part is to train yourself to do a 100% stop without flipping over or washing out the front. What you are doing takes some balls lol i've washed out the front and i've slid the front like you did before without crashing and its effin scary. Good on you for practicing :ok

Well my front end is already F'ed up from the crash, so I thought it'd be a good time to practice some crazy things! Sliding the front is such an adrenaline rush that makes it kinda addictive :P Yes, I did gradually increase the pressure on the lever, and yeah, I wanna get a feel for when the rear is almost/completely up!
Does it have anything to do with the brand and condition of the tire, given that it is not a knobby from a wr250 :D ?! Should I try reducing the pressure a bit? Bigger contact patch?

If the tire is old or a harder compound it may make it slide more... depending on what the pressure is now. Yes lowering the pressurr could definitely help!!!

No, munch, not lowered. Wanted to do it but decided to not bother!

okay guys, thank you. I'll let you know if I succeed!

Found the problem! Hahah yeah that probably won't bite enough.

In all honesty, knowing how to react when the front is locked up is a MUST in my book. What happens if you're going down the road and there is a big patch of sand and you have to brake? Or how about a slick spot on the highway because that accident up there, well it was caused by someone's engine blowing up! Yeah -- definitely a good one on you for trying these things out!

With many organic pads, it's best to let them gently break-in to the shape of the rotor, then you need to do some "extreme heating" cycles to get them to firm up and have the right bite down the line. I've lifted the rear a few times doing that! Only once ever for an emergency brake. None of this "6 o clock" stuff of course....

That actually makes a lot of sense! Though mine are quite old so they probably have that shape! I guess I just need to practice! Today I accidentally lifted the front for a moment, and I didn't react to it at all! I really need a stunt session!
Thanks man
