Wheelie question

[ital916]

Hey guys

Have been surfing kb for like four hours straight now *I'm on ordered bed rest due to respiratory problems...not cos I'm a geek haha* and just had a question..about wheelies. I know they are not big nor clever, but hypothetically if you were pulling one on a private road, on two different bikes. One with independant brakes and one with linked brakes, would it make a difference?

The independant brakes one you can cover the rear and apply only the rear, but with the linked brakes bike, if you apply the rear some of the front pots will activate as well. And I am guessing front brakes applied when landing a big wheelie = bad?? *I've never really tried pulling big uns, just accidental little wheelies when a bit raw with the clutch*

Just wondering, anyone had any interesting experiences with link brakes, I hear they are excellent in the wet.

Just a puff of smoke when the wheel lands.

Spend some more time on Youtube - there's one impressive one of a motard holding the front airborne for over ten minutes!

With the power of my deduction, linked brake system would apply braking to the front wheel as well as the rear. Due to the front wheel's minimal contact with the ground during wheelie, obviously even a little braking force can most likely result in loss of ground traction.
And we all know that loss of traction on front wheel = bad.
So, the conclusion is that wheelie + linked brake system = bad.

However, considering the front wheel is likely not to be touching the ground during wheelie, it cannot have any diminished traction due to initial traction being 0 (you cannot go less than 0 on traction factor), therefore the linked brake system would not have any effects.
Conclusion, linked brake system + wheelie = no danger.

Considering linked brake system in a wheelie resulted in no danger, then doing this on public road should not be a factor due to the absence of danger.
Conclusion, linked brake system + wheelie + public road = no danger.

Err...to your floating front wheel, that is...

Errr, despite never having had to use the rear brake to calm a wheelie down (engine braking has always sufficed) you should only be braking enough to bring the bike down, not braking the whole way. Once the bike has decided it's coming down, it can come down pretty fast.

Touch the brake to bring it down, then let go. Dont stay on the brakes while landing (front or rear, even with independent brakes).

Sometimes the shock of landing is enough to get the rear wheel skittering along the road if you're on the brake or engine braking in a low gear.

Tell that to the judge. I bet it'll get you off a ticket! You have way too much time on your hands...

Linked brakes for wheelies = a bad thing. Centrifugal force of the spinning front wheel keeps the bike a lot more stable.

The first step in doing a wheelie is to take a deep breath so that kinda rules you out at the moment.

Sorry I cant do a wheelie. I tried a few times when I was a lad 20 plus years ago........ Everytime I tried I flipped the dam thing.
Love watching them though.

You mean the gyroscopic precession? Heh.

Helps a bit, but depends on the bike really. Some are just nice and stable up on the back wheel and some aren't.

gahaha touche, due to extreme boredom I must have read every bike review on the net, reviews of all bike gizmos and stuff. Getting interesting, I quite like the idea of linked brakes on the road..must suck in twisties though.

Why is that?

[AlBundy]

Another question is....

When having linked brakes, how easy is it to do burnouts?

Add to that, when doing stoppies, what would the effects be? Totally different weight transfer to the front? Quicker rise due to no rear wheel spinning?

Linked brakes have a bias toward whatever one you've put on. It's not like you put the brakes on and both wheels are braked evenly. They're not.
You put the front brake on, most braking force is happening at the front, with a little in the rear. You put the rear on, and most of the force is happening in the rear with a little at the front.

Why is that?

Perhaps he wasn't listening at RRRS when they talked about the rear brake helping to settle the bike.

Also the fact that most linked brake systems only work one way - i.e back brake does rear wheel only, but the 'front' brake does both wheels.
