I picked up a set of used magnesium R1 wheels for track use last weekend but the rear wheel is missing some parts, namely the plastic holder for the cush drive blocks, the sensor ring, and that big plastic toothed wheel that bolts onto the hub behind the rear brake rotor. I highlighted the parts needed in the attached image.

If anyone has switched to fancy aftermarket wheels on their late-model R1, or just has any of these parts lying around, I could really use them. :giggle:
