: R1 flip over
01-16-2002, 08:26 PM
Will the R1 flip over doing a full throttle roll on in first gear? The raeson iam asking is because the front end of my zx9 would come up fast and hard during full throttle roll on in first when the rpms would reach about 9000. Thanks:eek:
yes it will.
R1s will do power wheelies in first gear starting from 4000 revs.

There are rumours of test riders(when the R1 first came out) whacking open the throttle in first and being hit in the visor with the edge of the windscreen! That's a yes:p

I did that when I fitted a taller windscreen.

<~~~~~will do that to your @aa if you throtle it wide open in first "little pic over there"
First gear isn't the only thing to worry about....a month or so ago, i was riding in the third lane on the highway when i spotted a car merging without signaling, so for the heck of it i figured i'd down shift a couple gears,move into the middle lane and just smoke by him. Onle problem was i accidently downshifted to 2nd gear,at 70 and wacked open the thortlle and guess what? It came(and fast) at which time i was fast approaching a car doing all of 40. To say my heart jumped through my thoart is an understatement! Somehow i shut the thorttle, veered right onle to encounter a tankslapper upon landing that snapped my hands right off. Incredibly, the handlebars correcteed itself and i proceeded fairly humbled by the whole experience.

All i can realy say is maybe you should try riding in the parking lots more till you learn your gearing,
But on another note SAY WHAT? You wacked it wide open in second gear and it scared you? Maybe you should "Shhhhh" look into getting a honda or sumthing:D i mean come on fella its not rip the asfault out from under you trying to get away. You just need to get used to power on comand:cool:

I nearly trashed my baby trying to make a wheelie ones... Full throttle and up she went.... that was in the beginnig of my bikeriding life....

it'll do it in second

The R1 in first gear is just like riding a 250cc dirtbike. If you keep giving it throttle it will flip no problem. It's a madman bone stock.

HAHAHAHAHAHA........ will it flip over if you whack the throttle full open.... you say you zx9 would do it? well just dont try it on a R1, its not as forgiving as a zx9 trust me.;)

Let me give you some technical background on this question, for fun.
First, in basic terms, torque is a way of quantifying the angular effect (moment) of a force applied at a distance with someting to connect the force to that reference point (origin). Mathematically, it is a cross product T = r x F, where T is torque, r is length, F is force. The x symbol does not just simply mean multiply, but to keep it simple, if the angle between the 'r' and the direction of the force 'F' is 90 degrees (perpendicular) then you can just multiply the two (ex. 20 inch rod held horizontally with 10 lbF hanging on the end applies about 200 inch-lbF of torque to your hand).
Most of us first knew the term from a torque wrench, which is statically applied (i.e. you can apply torque without constant motion, the bolt doesn't have to turn and the wrench doesn't have to move for torque to be present). A motorcycle applies torque dynamically (i.e. the engine must stay running to maintian the torque). Actually, on a torque wrench, your muscles apply the force somewhat dynamically, that's why your arm shakes when really straining.
Second, in a wheelie, the rear axle is the 'fixed' dynamic point of reference (origin) for the torque we want to discuss. The weight of the bike and rider acts as if it's concentrated at the c.g. (center of gravity). The distance between the c.g. and the rear axle is at a maximum when the bike is level (horizontal) because the force is vertically down (gravity) and 'r' (the rod, let's call it) is horizontal, so we can directly multiply r x F to get T.
Third, now for the real point... the torque created by gravity goes down as the bike comes off the ground because the horizontal 'r' gets shorter between the force 'F' at the c.g. and the rear axle. ***If the engine can create enough torque to get the tire off the ground in the first place, and the resistive torque created by the bike weight goes down as the wheel comes up, then you can ALWAYS flip the bike over backward, because it takes less engine torque to flip over than it does to get the front tire off the ground.
Fourth, the reason that you don't go over backward, is that once up on a wheelie, you usually let off the throttle, or you lean forward, or both, or you accelerate the bike which also dissipates torque (kinetic energy into momentum). By leaning forward, you can effectively move the c.g. forward a little, creating more torque from your same body weight by moving it further away from the rear axle. The fastest racer doesn't pop wheelies, because he/she uses the maximum resistive torque so that more engine torque can be used.
Fifth, what useful tips can be derived from this?
1. Don't lean back when popping wheelies. You really compound the drop in resistive torque.
2. Be prepared to ease the throttle when the wheel comes up (this usually happens naturally because your hand rotates off-throttle when the bike rotates up).
3. Be prepared to lean forward damn quickly, because the bike wants to move your weight back as it comes up.
4. When riding a 'balanced' wheelie like you see the pros do regularly, don't be fooled. They are damn good. In this case, the bike torque is balanced and one little rock backward and you'd better be ready to hit the rear brake.
5. Why does the rear brake bring a wheelie down? That one is easy... your reducing the engine torque by offsetting it with brake torque. Just be careful, if you over-do it you'll come down hard and do a tank slapper. Most people who pop wheelies for the first time apply the rear brake without knowing it, because your foot tends to rotate down (on-brake) as the bike comes up. The people that tend to go over backward are those that have just mastered the process, because they unknowingly train themselves NOT to roll off-throttle and on-brake. Also, they tend to get more confident and look up to see if anyone is watching, instead of looking at the ground to see if they are popping a wheelie or not. This really affects the c.g. (your head+helmet weighs a lot more than you think). If you are not wearing a helmet and spine protector with leather jacket when doing balanced wheelies (at a minimum), then you are really risking your life. The most common injury when going over backward is not a head injury (if wearing a helmet) - surprisingly, but it is the most life threatening. The most common injury is groin and abdominal muscle hyper extension (pull). Why? When you go over backward onto the ground you really tense those muscles and your body is 'folded' when it hits. When it 'unfolds' you go flat and spread eagle, and with muscles tensed due to instinctive falling reaction, you really do a number on them.
Hope you enjoyed this.....

Bet you can't say that 3x fast.
Typical Engineer, he can put in writing how to do it...

Here is My Formula for the last wheelie I pulled :
Here is the breakdown:
Eight beers times too much throttle equals six months off work :yesnod :lol
Be careful wheelies can hoit ya badd :cryin

I mean, REALLY, you sound like a guy writing a report for the national hiway insurance institute or something;)
To cut to the chase.................. respect is good on an R-1, don't be an idiot with the throttle on one if you are inexperienced, unskilled, or both:no
And lastly, get used to the simple fact that unless you are an absolute boner:iamwithst and ride like a old woman, riding an R-1 with any REAL vigor will, invariably result in wheelies. Some wanted and predictable:cool: , and then there's the sneaker dip in the road, crest of the rise 3rd gear 110mph jobbie that occassionally pops up to play, says" tag, you're it ", just to see if you are paying attention.;) All good fun, but make sure you're THERE when yankin' the cables in any gear:yesnod :thumbup

all big torqued sportbikes do that...its not exclusive to one brand or the other,750,900 or 1000.
