This are some Motorspurs made for the @torqueboards 6374 Motor.
After some Customers needet to modify my standart pulleys this ones should fit directly. Removed the Hub, added a 3mm Keyway and a Setscrew inside the flanges. But as on some other Motors the Motorshaft itself has to be shorten do 27mm. 30€ more for the Dual Drive with this.
