More than likely a clearance issue with the front bearing hub, but you could drill out the middle of the spacer to make room. Im thinking about the spacer for my medusa as there are only 2 25mm spaced mouting holes- strip one of those out and you're buggered. Fixing the spacer to the front only gives you 2 spare holes again, but if you strip them out, at least it isnt on the motor. I believe the spacer is 36mm diameter, same as the motor, so its only any use on a neu or hacker or other finned motor towards the purpose of clearing a brake disc or caliper etc.
