You cannot compare just engine torque numbers, without adjusting for gear ratios, wheel size and sprockets.
As another commenter said, you rev a Ninja (just like a sports car) and launch it using the clutch.

In fact bicycles are fastest off the line, since they produce max. torque at 0rpm (just keep weight on a pedal, release the brakes to go). But acceleration is modest, so motorbikes and cars will soon go past.
And of course electrically-driven vehicles are also capable of producing torque at 0rpm, hence their acceleration advantage.
Of course, for touring there's now the H2 SX Ninja(!)
I doubt a bicycle would actually cross the starting line before a high end bike or car would surpass it. A 180lb rider would produce about 90lb of torque at most (assuming 6” crank) and that’s only for the instant that the crank is parallel with the ground.
A high end car would deliver significantly more than 90lb of torque instantaneously by dumping the clutch (or using launch control).
If you aren’t standing up sprinting, you’re definitely not going to be getting anything close to your “body weight torque”.
Having said that, I am very used to riding bicycles and (large) motorbikes around town, and from waiting for lights to change if I'm on a bicycle I'm generally first away even when motorbike riders are getting competitive (never mind cars).
The advantage of the bicycle is generally only a few feet, of course.
The Veyron might weight 20x as much as you and your bike, but has over 300x the power output of the best sprinters in the world.
Given equal reaction time and equal interest in racing, I am doubtful your cycling advantage would last for more than inches against a high end sports car.
In a racing start, a well-driven torquey car (like the Veyron) will also launch faster than a motorbike - at least to start with. Once the speed increases, the acceleration drops and the motorbike can then use its superior power-to-weight ratio (which it can't fully use off the line). Eventually - once speeds are well into triple digits - a fast-enough car starts to catch up with the motorbike again (due to better aerodynamics).

I can get off the line faster then automobiles, they aren't racing / clutch dumping at the lights. Traffic is so heavy and with so many intersections, it's typically pointless for automobiles to race off the line anyways.
As I filter past daily the same Pagani and Bugatti and LFA and Tesla S and NSX. :D
Once you are in third though displacement takes the lead, and my smaller engine bike is at a disadvantage!
