    I have to respond to this.

    You're missing some physics. Kinetic energy is a square function - it equals half of mass multiplied by the square of velocity. Something weighing half as much as something else, but travelling at twice the speed, has TWICE the energy. Your 250kg at 200kph will hit twice as hard as a 500kg mass travelling at 100kph.

    But since cars are actually at *least* four times the mass of your bike, your hypothetical 250kg bike and rider at 200kph has the SAME impact energy as a 1000kg car and occupant (say, an MX5, or Starlet) hitting at 100kph.

    And we all know how much mess even a smallish car makes when it hits something at 100kph.

    So think about physics when you twist the throttle, and don't be too cavalier about the potential consequences of high-speed riding.

    I'll take on any bike with my Pajero....Micheal Schumacher taught me how to drive - you are allowd two moves - one to knock the wanker off his bike,another to back up and finish him off.

    Dude, just on the quiet, i'm trying to grow some very very special gunja in quiet plot known only to the aliens and me. Except they're stuggling a little. Slightly burnt edges and not as quick as i'd like the wee buggers to grow.

    I need a man who has a LOT of expericence with these herbs bro, and it sounds like you're my man. I'll fly ya down, put you up, anything - just as long as i come out of it with some fucking good herb bro...

    I'll even let ya ride my electric step-thru... it eats porshe GT3's in the tight stuff...

    Is this serious? I hope not - but I have heard it many times from different fellow bikers that they reckon any old bike will beat a car through the twisties.

    It just is not the case. Sure, a bike will accelerate out of a bend faster than a car, but a good car, driven well will do the corner itself faster than a bike.

    I've even experienced this myself; I used to drive a BMW 330, and although it wasn't the fastest of cars it was pretty swift, and it had BIG tyres and good handling. I could actually out do 600's, 1000's etc. on a very twisty section on the way to work. (There wasn't enough length of straight for the bikes' acceleration to win out). I could brake later, and corner faster.

    And if you think the bikers just weren't very good riders - it's not that, it's just boring old physics. Cars have good a much greater area of rubber in contact with the road, and the traction really makes for better braking and cornering, even when you take into account they are much heavier..

    Man now im confused. So i usually do 120 or less on average on my bike, but know u want me to do 1/4 of that in my car. sorry i missed the point here.
    What is said was:
    A car travelling at the same speed as a bike is going to do more damage than a bike.
    and i get bad rep for it
    Either some one here doesnt believe this, or their lying.
    one point too JR that i learnt was cars absorb impact, as do bikes. However motorcyclist also absorb impact during an accident (the drivers absorb a minor amount). So effectively the motorcyclist would be 1st to die, car driver 2nd.
    Unless the car, hit motorbike, rider flys. But thankyou JR for pointing out kinematics to some people here As some believe a car CAN travel as fast as a bike on the roads. Your a cool guy
    Now in my final statement.......I am not some lunitic u all percieve me to be Infact my worst accident i have ever had, i was only doing 35kph. I have thrown away all my childish needs many years ago. Infact my last bike was a GB with a top speed of 140 down a hill.
    And to those of you, who still dont believe a am the semi-old type now.
    Bite me cos the rest of u seem a cool group of guys

    Half true.

    Performance Bikes did a test two years ago between a modified WRX, a Gixxer 1K and smelly old GS500.

    The GS500 bet the car in every single test except the braking.

    On the cornering, the bike would go to the outside, inside, any way the rider wanted.

    contary to what you think I recon the bike can do more damage than the car... See when a car hits something head on, the force is spread evenly across the entire front section of the car hence the crumple zone gets to work effectively. But when I bike impacts a car, that force is transmitted thru only a narrow section of the car.... 1/2 meter at most. Hence depending on where you hit, the passangers / car can be worse off than hitting another car...

    we bikers really need ejection seats... helps to clear us of oncoming cages

    see the damage a bike does to cars.... check out the attachment.
