Although the weakness of M1 can be covered with the flexibility to bend the frame when the corner, but sometimes the machine does not respond as expected the rider as it passes through the straight track.
“Sometimes, traction control and interrupt control wheelie rider itself. When drivers want to accelerate, and the rear tires began to spin, or spin in place due to excess torque or power, sometimes the response is too late or even wrong ECU. Thus the accuracy of the moment between rider and response control ECU becomes very important. You could say this is a very critical zone, “said Nakajima.
Yamaha also end up changing the rigidity or stiffness of the frame to be able to meet the target to increase the acceleration of M1. Because the 1000cc engine has a torque greater, then the Yamaha trying to maximize the potential to improve acceleration, and manipulate the character to make it more friendly to the rider so that the motor is not wild and easily controlled.
