My attempts to break 4 seconds yesterday... still haven't been able to do it. Any tips?

I remember having read that the 3.3s for 0 to 60 was done with a rider of 6? kg...

First 60MPH is 96,56 km/h =26,82 m/s, going to 100km/h will take longer time.

lets say they used a 62 kg driver for that giving a total weight of 250kg

this gives a total Energy (not counting drag) spent of E=(mv^2)/2 = (250* 26,82^2)/2 = 89,93kJ

As far as i know the bike does lash out more power at 100km/h compared to lower speeds, so that may cancel some of the power wasted on drag- which lets us assumeclose to constant power spent on acceleration. Given linear power output we have 89,93kJ/3,3s = 27,25kW power

To reach 100km/h you would need to be 45kg (not counting the extra drag for going faster) to reach 100km/h using the same energy.

a typical rider may weigh 82kg giving a total weight of 270 kg => v(3,3s) = 92,91 km/h

at 100kmh he+bike will have 104,17kJ Energy.

Thus it will take approximately 104,17kJ/27,25kW = 3,8s to reach 100 km/h for an 82 kg rider.

Now the question is how much difference is there between the total weight of the bike+rider used for achieving 3.3s on 0 to 60 and your bike with you on it?

Are you able to cause less drag than was present at the 3.3s attempt?

...

slightly above 4s for 0 to 100 seems quite nice in my opinion
