No wonder...When I rode a C751B, it was jerky whenever it
stopped...
C751B different case.
Only an extreme noob TO can do that. o.0
C751B have extremely powerful controls.
And its use a very pro braking system and method.
But i'm not too sure the "jerky" you mentioned.
Even in auto mode, C751B uses a slight jerk method.
Do check out for the orange light at the first cabin.
