Designed from the ground up to give unmatched torque and power, without suffering from all of the issues that plague the stock sur-ron motor & controller offering. Easy to fit! Both the motor and controller are designed to be a plug and play option in the Sur-Ron and are easy to fit, using the same cabling and also the same default Sur-Ron display unit. Gone is the need to upgrade your display unit and run additional extra cabling across your bike.
