What is the max torque on a bike?

Maximum torque And when your motorcycle has more than one cylinder, the torque of the individual pistons add up. The rpm where the maximum torque is delivered, is the rpm where the fuel is burned most efficiently: it is at that rpm that the piston delivers the maximum torque on the crank.

How tight should a carbon steerer be?

Usually, 6-8Nm is enough for that purpose. You can lower the required torque by adding a carbon friction compound, sometimes called carbon grease. It increases the friction between the steerer and the stem clamp and will therefore require less clamping force to stay solid.
