IMPORTANT NOTES
-
This motor exceeds UK road legal limits (250W max). It is intended for off-road, private land, or export use only unless properly licensed or restricted.
-
Always use the supplied disc rotor bolts. Using bolts that are too long can cause internal contact and prevent proper motor rotation.
-
Minimum disc rotor size is 180mm. We recommend using a 200mm rotor for optimal braking performance due to the motor’s power and weight.
