The motor is very good for updating the Razor MX650, we have a customer wrote a post here:
The sprocket on the original motor swapped directly on the the brushless motor with no modifications and was a perfect fit so I ran with it. One point to notice is that from the face of the stock motor to the middle of the sprocket was 14mm. From the face of the brushless motor to the middle of the sprocket was 16mm. This was resolved by putting a 2mm washer in between the face of the motor and the motor mount thereby holding the motor back such that the sprocket was in the original position. You’ll notice there was a 10mm difference in length so on the backside I needed 8mm spacers to make up the difference. A combination of a spacer and a washer was perfect. Ace Hardware had them. The mounting holes were identical to that of the original motor and the original bolts were long enough that they could be used so the swap was easy. The new ESC is a bit larger but will still fit in the existing location. I placed it up where the 3rd lead battery went as I’m not using that area.
