Stopping via stoppies

1. ## Stopping via stoppies

Hey is it better to keep both tires on the ground when braking HARD or doing a stoppie?

I am just wonder as today I practiced braking HARD at a variety of speed under 100 and found that I usually ended up doing a stoppie then the rear came down hard. I take it they are a little hard on the bike but so is everything else.

3. how do you do a stoppie with 2 wheels on the ground??

4. For 100% stopping power your rear tire had to hower one hair above the ground.
Stoppie redirects forces in the wrong direction same as keeping tire on the ground.

5. dont forget u have 2 brakes. For best braking the rear tire should not come off the ground. practice using the front, rear Plus engine compression.

6. Erm... did you read that wrong, Gary?

Hmm... I would think it depends on numerous factors... different bikes won't have the same answer...

As a total guess, I think it would be the maximum angle of a stoppie, with as much brake applied without the wheel locking up, without the bike wanting to rotate forward past the equilibrium point. Different bikes will have different equilibrium points, depending on suspension setup, weight distribution on the bike, etc. At the maximum angle, you should be at maximum grip... the maximum force with the deceleration and the weight of the entire motorcycle would be driven into the ground at the point of contact on the front wheel. This maximum angle is not going to be very high at all... maybe a few degrees or something with the rear being just slightly off the ground... a lot of bikes probably stop better without the rear tire ever leaving the ground...

It might be somewhat opposite of how you would get maximum acceleration... as you see in pro motorcycle racing... they would bring the front end up just a few inches at certain times...

Don't take my word for it though... LoL... this is completely an uneducated rambling... but sounds logical to me...

Under heavy braking, if you keep the rear on the ground, I think the rear does very little to reduce speed. There's hardly any friction going on back there between the tire and the ground because the weight is almost completely in the front due to the inertia and deceleration.

7. Like Fish said once the rear comes up more than about an inch then you are not able to stop as hard as when the bike is more or less level. What he didn't add, other than through implication perhaps, is that once the bike comes up to a serious angle you can't maintain the same stopping rate as the center of gravity is raised and the bike is easier to somersault. In most situations this will lead to a lack of control and crashing into what you are trying to avoid or flipping over. Keep the bike low and more or less level. But basically you're working on the right idea. LOTS of front brake until the rear is just hovering without coming up very far or at all is the fastest way to stop a sport bike with it's short wheelbase and sticky tires.

Also if you want to keep doing this sort of practicing that's great but be sure your front tire is warm before you really put 'em on or you may find it wants to skid rather than lift the rear.

8. Fish and Tee Tee, have got it, but there is an advantage to using the rear break with front. If you going fast and have to stop quick, and the road happens to be bumpy or in bad shape, using the rear break helps to settle the rear of the bike. I use this method a lot in MX, street and at the track, the trick is to know how much rear break you need, this comes with experience, but it isn't much. It isn't all ways needed, but when you do feel the need it help alot.

Using the rear break will make the rear suspension squat, and this forces the back tire to stay steady and staight on a rough surface, it works really well. It does take a bit of practice, but be very smooth and gentle.

9. Oh great.. now I have to warm up my front tire before that truck pulls left in front of me. Just another thing to remember...
Sigh.. ABS was just so easy...

10. Yeah today I noticed that if I keep the back down or even on the ground (atleast it felt on the ground) it would stop quicker than doing a stoppie with the rear up in the air.
I also noticed that I love to lock up the rear and have the back end skid all over the place, but the tire doesnt like this and there are rough patches on it so I have to stop doing that.

ANyways thanks, I always use teh rear break even if the rear isnt on the ground and I will try to keep it from stoppieing the rear up too high, if that made any sense at all.

Unless you're trying to do a nice one then it's all good. Stunting is a valid form of bikeing in my books even if you won't ever see me trying it.....
