The KO FSpec Motor is the highest spec, direct fit replacement for the original Surron motor. With many battery and controller options available for the Surron LBX and L1E, the weak point in power modifying is the motor, with the standard motor burning out on high power builds. The KO FSpec motor is capable of a massive 35Kw power output while keeping cool and working efficiently, ensuring consistently high output, without the cutting out of the standard motor overheating.

Please Note: This is an upgrade over the KO RS Motor by providing more torque, higher rated rpm and a top speed capability of over 90mph+ depending on riding parameters.

It’s highly recommended a Heavy-Duty Primary Belt is installed for road style use and potentially a chain conversion if used off road, simply to handle the extra power. A primary chain is recommended for very high-power builds and offers more resistance to debris but will increase noise.
