Wheelies, wheelstands, monos etc

[jrandom]

I think it's just the rotational force of the wheel. Turn the bars to the right, bike turns left. Turn bars left, bike goes right. Magic!

Yeah. Wot 'e said. Force perpendicular to a plane of rotation. Gyro-thingy pre-wotsit, innit.

Give that a quick dab mid wheelie and watch out for ya nuts!

I was hoping everyone would keep quiet-like, and SC would learn about the details of the physics the fun way.

Should'a kept me mouth Sorry.......

Gyroscopic precession

isn't it progression, how forces applied to something in rotational motion are experienced 90 degrees aound in the axis of rotation??

Try sitting in a swivel work chair and hold a bicycle wheel by the axle, get someone to spin the f**k out of it and then try tilting it side to side and left to right, you should be able to turn youself around in the chair, this will give you some idea of whats happening when you push on the bars Stonechucker, and it aint all that hard to do either.

You do well to question the word; my memory is very leaky. I was right this time, though. From dictionary.com:

pre·ces·sion
n.

1. The act or state of preceding; precedence.
2. Physics. The motion of the axis of a spinning body, such as the wobble of a spinning top, when there is an external force acting on the axis.

So, er, there you go. I think.

Good idea.

ok delved into the 7th form notes and throughout it is referred to as progression, so blame the education system!!

Little pic attached from same notes shows what I am kinda on about, the gyro would spin in to the screen instead of falling as imagined

Good to see someone else has got an 04 R1. Awesome bike. On the way to work and back today I tried a few roll ons in 1st, just got the wheel off the ground then ran out of space/ balls.
Typically I was on SH1 overtaking in 3rd hard and without trying the wheel came off the ground a few inches. This bike is soooo designed to wheelie, If I can't do it on this I'll never do it.
Wonder where the best place to practise would be in West Auckland? :cool2:

Swanson Road, around 11pm on a Saturday night

Yep your R1 sure has some mumbo...... I remember on the track when i got a good 2 bike lengths on you out of Castrol, then literally watched you twist the throttle and fly past me....

Best place to practice would be a very long smooth road in some industrial area....usually on a weekend or in the evening.... otherwise a very straight long piece of road out in the rural area that isnt travelled on very much....

Stupid education system.

Good picture.

Gyros are weird.

Anywhere there is not a cop . Sooooooo no-ones offered me thier bike yet . Hmm i'll just have to wait untill i get the funds for one. Untill then it's clutch hi-ho silver.

p.s. does anyone (with a smaller bike) have a good clutching technique, i can get the bike up to about a 40-50 degree angle with a bit of control. But that only happens sometimes (when i have the balls)i am usually in the 25-35 degree mark. Well that's what i think from the handel bar position. I really need someone to film me so i can analyse the whole thing.

[StoneChucker]

Yeah, I know what gyroscopic precession is, and how it works (was covered extensively in a certain course I did)...

I may have a go sometime, but as you say, it's bloody risky!

[avgas]

i actually have the opposite problem - bikes dont turn very well with the front in the air. Dont worry mate - you'll work it out. Get some crash bungs if your gonna practice thought - even take of your fairings, headlight etc if you think your gonna stuff it up.
Are wheelies illegal in NZ? Anyone know?

[Kwaka-Kid]

talk to my older brother, this pic is of him at about 14years old on a 1978 Honda XL125 - beast of a bike! -he doesnt ride anymore unfortunatly.

hey avgas whats the best way for the zxr400's. I am clutching at the moment and am good with anything up to about probably 0.5m but anything bigger and the revs required mean that i have less control. Nott a good thing.

p.s. what are up with cable ties on the forks, where do you put em what do they do etc etc etc
