KO RS Spec Motor - Surron - Blue


£899.99 £749.99 ex VAT

In stock

The KO RS Motor is a 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 RS 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.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.
