The B40 Competition comes with larger bearings than the regular Hacker B40 and the front and rear plates attached with screws, both of which significantly reduce friction and improve the durability of the motor. A larger sized shaft with a diameter of 6mm and a strong gearbox help to eliminate vibrations at extreme speeds and increases power output.

Brand new outer case designed with milled cooling channels allows for increased heat dissipation at a very low weight, while an internal fan also improves cooling. The asymmetric air outlet helps to keep the level of noise to a minimum. A high degree of efficiency is achieved by a new, segmented high-performance rotor from optimized magnetic material.
