Question:

What is the maximum required safety speed a motor bike should maintain at a gradability of 11 degrees?

Answer:

From a legal point of view the required speed of any vehicle is relevant to the speed limit of that particular area, i.e. 60km/h, 120km/h etc. as set out by the relevant road signs.

 

From a safety point of view the, depending if it is uphill or downhill, should be enough to remain in control of the motorcycle at all times. This speed is usually 12km/h and more depending on the situation and road conditions, straight line or in a bend. It is also important that you select an appropriate gear and maintain power to the rear wheel to prevent to motorcycle from stalling while moving off. From the move off point throttle should be rolled gradually and in a smooth manner as to prevent a wheelie or a forward launch.

 

Perhaps you can explain the purpose of this question.
