Well not many bikes that can do that. In the real world a ZX10R will spank - lets say a Ferrair 360, but given a long enough road (not likely unless 3am on the M1 ) and the 360 will catch you and pass you.


If you was riding your ZX10R @ 80-100mph on the motorway and had a 360 modena creep up behind you, then from that speed accelerated you would pull a huge distance from the car that by the time he started to creep over 180mph (ZX10R top speed), the race would be finished. If you just happen to be doing 150mph on your ZX10R and a 360 appears in your wing mirrors, and you then accelerated - the distance initially, that you would pull would not save you from the 360s huge 195mph top end. A bikes acceleration the faster it goes tends to suffer greater then a very fast car.

Cars to watch and are likely to meet, are 911 Turbos, TVR Cebera's 4.5L V8s, TVR Speed 6's. These cars have very strong acceleration from 120mph.





And before people mention that bikes Aeoro's are crap, no they are not! Just consider that 160bhp is always going to have a hardeer time pushing through a 150mph gale then let say 450bhp.

This is a good article where lots of VERY POWERFUL tuned to the max cars are pitted against eachother. They also chucked in an MV10000S ofr a comparisson.

Note how week the MV's acceleration is from 140mph against those cars. To be fair those cars are Tuned. Makes you think tho:) Also they put in a standard viper and corvette as well:)

The "license tag" he has on the back there is a sign from a US company called Overhead Doors, they make electric garage door openers and garage doors. Probably will always get by with it, though, could you imagine a police officer dedicated enough to shove him in the back seat of a car to take him to jail?

All well and good, but in all honesty, when and where are you gonna need to out accelerate anything above 110mph? I agree that the Ferrari would have thrashed the SV above 90mph, but this is already 20 mph beyond the speed limit. Quite frankly, if you all feel that your fun is to be had at 90mph+, then you may as well get a fast rep mobile and blat up the motorway. :smt107

[Fuzz]

A bikes acceleration the faster it goes tends to suffer greater then a very fast car.

This is true, and it's because bikes are so much less aerodynamic than a car. (Yes they are!) It has little to do with pure power - consider the power/weight and the power/displacement.

911 Turbo - 480bhp, 1585kg = 0.302 bhp/kg; 3596cc = 133bhp/litre
GSXR1000 - 165bhp, 180kg = 0.917 bhp/kg; 999cc = 165bhp/litre

Bikes aeros are much worse than cars because of us. We might tuck in as much as possible, but them hips, elbows, head, *bottom all add drag. Consider that the bike is also smaller, and therefore hitting less front on "150mph gale" and you can see the wind resistance isn't the problem, but the drag created at the back. Bikes and riders create strong turbulence behind the bike; sports cars are designed to minimise this, and the size of you - other than adding weight - has very little impact.

high speed is all about drag, as it is proportional to the *cube* of the vehicle speed, ie - to double the top speed of a bike without changing it's aerodynamics you require 8 times the power...

http://www.bgsoflex.com/airdragchart.html
http://www.motorbyte.com/mmm/pages/misc/tularis_22.htm

probably explains it clearest:
http://www.qsl.net/n5mya/aero.html

With figures
for both drag and frontal area, it's possible to calculate the coefficient
of drag, which is 0.603 for the 12R and 0.561 for the Hayabusa. The
winner of this wind tunnel shootout is the Suzuki.

...

It's worth remembering, however, that neither of these Cd figures indicate
a particularly impressive degree of streamlining, since even a typical
passenger car has a Cd of less than 0.60 and some models are lower than
0.30. A fully streamlined Bonneville speed-record bike might have a
Cd of 0.10. Such is the nature of streetbikes, where performance derives
mostly from extreme power-to-weight ratios.

Precisely, so if a bike were as aerodynamic as a car, it would require the same amount of power to hit 200mph. The Cd figure alone isn't of much use, because you need to consider the frontal area. A bike might have a Cd figure of 0.650 and a car have a figure of 0.600, but that just means, simply put, that the car disturbs less of the air that it hits than the bike does, but the car still hits a lot more air.

sorry but the drag coefficient is dependent on the frontal area of the object, so the fact that cars have a greater frontal area is taken into account when their drag coefficients are calculated.

Sorry back :), I think you're wrong. A flat board at a 90degree angle to the road could have a Cd of 1.1, and so could one of 5 times the size. Which would make more drag?

The value that makes the real difference is CdA, which is the combination of Cd (drag coefficient) and frontal area.

As already mentioned it is the dirty air, not to mention the elbows, the feet, the head, the hands and arms creating servere drag. I remeber reading a PB or SB article a good few years ago. CD was around 3.4 but went over 6 once rider was astride. This is the case for Most bikes.

Bikes are more aerodynamic than a car. How many cars with less than 200bhp can hit 170mph and higher?

How many bikes weigh 1.5 tonnes? Im sorry but weight has everything to do with it - to do 170mph you have to start from 0. If you don't have the power to accelerate 1500kg to 170mph, you'll never get there unless dropped from a plane.

It's not just the bike you have to think about; do you still perfectly still and rigid while you're onboard? The shape of the car does not alter, the shape of the combined bike/rider does.

It's not just the bike you have to think about; do you still perfectly still and rigid while you're onboard? The shape of the car does not alter, the shape of the combined bike/rider does.

The weight affects rolling resistance, but that's less that 10% of the equation, and FYI: a car with 200bhp weighing 1000kg will have a maximum very close to an otherwise identical one weighing 2000kg.

The weight determines how quickly the high speeds are achieved, and has much much less effect on how high that top speed is.

If it were not for wind resistance/drag, it would be (excluding the small part that rolling resistance plays, something that increasing tyre pressures can largely overcome), just as easy to accelerate from 100mph to 110mph as it is to accelerate from 0mph to 10mph. You need the power to overcome the wind resistance/drag, not to accelerate the mass of the car.

So no, weight does not have everything to do with top speeds, but of course plays a big part in 1/4 mile times.
