Aprilia RS 457 Steering Stem RAM Mount RS457

This is a RAM mount that attaches to the steering stem nut. It uses an 8mm RAM ball that is sold/intended to be used with the handlebar clamp. An STL for the RAM ball and shaft are not included, I used one I had sitting around, but may add a 3D printer ball to go with it at a later date. They are available at the typical shops such as Revzilla.

The 8mm threads are printed in, but it wouldn't hurt to run a tap through it before use. To remove the mount after it's been tighted, loosen the bolt so it sticks up a little then tap it back down with a hammer to loosen the wedge.

The relief in the base is sized for a 13mm diameter shaft.
