The VTB RYUGA 81kW Hairpin Motor is a high-performance upgrade for the Sur Ron Ultra Bee, delivering massive acceleration, stronger torque, and superior thermal efficiency. Its hairpin copper winding design provides higher efficiency, lower heat, and stronger sustained output than traditional motors. A reinforced steel-alloy shaft, precision-machined housings, and IP67 waterproof connectors ensure durability in demanding off-road conditions.
With up to 81 kW peak power, the RYUGA transforms the Ultra Bee into a true high-power machine with explosive launches, smooth throttle response, and top-end performance. It installs using OEM mounting points and pairs best with a high-output controller and battery system. Built for riders pushing the limits of electric moto performance on trails, track, or competition terrain.

fast shipping, fits perfectly. my son is stoked with it, great gift idea for any e-moto rider
