Well, one thing to keep in mind here is that if Torque is Weight * Distance…you’ll get A LOT of weight if you shorten the distance. Imagine instead that you have those 140Nm about 1cm from the centre of the rotating axis?
14kg * 1m = 140Nm = 0.01m * 1400kg.
Should, if you boil it down, be able to set a 165kg motorcycle in motion, don’t you think?
There is a lot more to the equation than that, but…uh…my perfectly typical hatchback has a torque number at 350Nm or something like that. 140 on a motorcycle sounds like more than enough, even with that simple comparison.
