The spacer on the inside looks ok to me.

I'm in the middle of rebuilding one at the moment.

I'm not sure that the thickness of the disc and sprocket shouldn't make any difference as it's the spacers that give the overall length between the rear forks.

iv got the seal took it off to check the new bearings on that side were fitted correctly , i ordered a new one as i split it when i took it out ,

no then the sprocket is out of line by the thickness of the offset

No, on a normal bike it would be, but as aprilia have mounted it the reverse way to anyone else (clamps on the side away from the centre of the wheel rather than a face towards the centre) that fix is not an option, the best way I found was to but a series of spacers between the shoulder on the stud and the mounting face.

I would have used a ring with the holes in it but couldn't find a bit the right thickness.

If lots of people are having the problem and are using the same fix it may be worth getting a batch laser cut and divying them up.

I changed mine to a Talon 42T rear sprocket last spring, and the threads are close to the swingarm weld, about 1mm gap if that! But not rubbing.
Isn't the sprocket/carrier mounted incorrectly. You should have the recess off the sprocket facing away from the wheel, otherwise won't the chain possibly become closer to the outer edge of the tyre

So who is selling these sprockets for Falcos that are not fit for purpose?

Seems like someone needs to have a word with the manufacturer to get them to make them with appropriate dimensions for the application .............

I think mine is a DID kit, I'm pretty sure someone who had the same problem when I had mine reported the matter to them, but I doubt anything came of it

your mounting ring would work for the bolts , but it would not close the gap from the wheel hub to the face of the sprocket where road grime would get in if it wasint tight
