This is the factory permanent magnet synchronous motor (PMSM) for MY24-25 Surron Ultra Bee models, cross-matched to part number 11100-YQ5A-Z2 (also listed as 11100-YQ5A-11B0). Built with second-generation hairpin winding technology, it raises the copper fill factor inside the stator for better efficiency and faster heat dissipation than earlier Ultra Bee motors. Embedded permanent magnets boost torque density while improved weak-magnetic performance lets the motor spin up to 7,000 rpm, unlocking the stronger top-end this generation is known for. The assembly includes the front primary belt pulley and is not compatible with MY23 Ultra Bee models, which run an earlier motor generation entirely.

Features
Highlights That Set It Apart

Second-Gen Hairpin Winding
Uses hairpin-wound copper construction inside the stator, packing more conductor into the same space for stronger cooling and more consistent output under sustained hard riding.

Comes With the Belt Pulley
Ships complete with the front primary belt pulley already installed, so you're not sourcing that piece separately or matching it up after the fact.

Built for Higher RPM
Enhanced weak-magnetic performance lets the motor safely reach up to 7,000 rpm, giving this generation its noticeably stronger top-end pull over earlier Ultra Bee motors.
