I was bored and decided to see how much power it takes for a bike modern liter bike, supra, luxury SUV to hit typical speeds.
Factoring in air resistance

Bike:
R1 696 pounds including 200 pound rider
.60 cD 6.1sqft

Supra mkiv/almost the same as a mustang:
3700 including driver
.32 cD 20.75sqft

SUV escalade/navigator early 2000's:
6000
.41 cd 35sqft

OKay the table bellow came out messy.
But funny how a bike takes
161HP to hit 180mph
262HP to hit 210mph

Yet a supra requires
355HP to hit 180mph
594HP to hit 210mph

People should be aware any high HP car will eventually start pulling on a bike. That's why i think if you don't pull the bike at 40mph and beyond you didn't win.


hp 30mph 60mph 90mph 120mph 150mph 180mph 210mph 240mph 270mph 300mph
bike 1.5 6.9 21 47 92 161 262 402 590 835
Supra 5.6 18 47 102 200 355 594 942 1433 2105
suv 10 36 96 213 414 734 1213 1901 2370 3438
