Designed from the ground up to give unmatched power and torque. You can now run much higher power levels without the risk of over-heating your motor.

The stock Surron motor has it's limits and can be prone to overheating when pushing high-powered tunes from aftermarket controllers. If you're a bigger/heavier riders (and/or racer), you've most likely encountered this. KO's Factory Spec motor was built to push higher power but keep temps lower. You'll likely never overheat the KO motor, even when pushing 15KW+ continuous.

Factory spec features a higher KV wind and magnets imported from Europe and a unique color set with laser etching and ultra high quality finish. 

Both the motor and controller are designed to be a plug and play option in the Surron and are easy to fit, using the same cabling and also the same default Surron display unit. Gone is the need to upgrade your display unit and run additional extra cabling across your bike.
