Yeah smart idea with NOT getting this motor. It may as be mounted on forks made of Swiss cheese
I saw this motor not too long ago on eBay. Its only this motor and what ever super high priced products are being sold by High power cycles, when you look up '"crystalyte" on eBay.
What I do with these is I mount them on a BMX in the rear drops, with torque arms and no chain, it makes for a proper little dirt bike that will eat any terrain.
I agree with you, the sight of any X5 over 48v in front drops is purely madness.
Anything under 48v and its a waste of a good motor.
