here a close view of the Axle. After the test we might rework all swing arm system . mabey thnking of cloning XR650 arm or a custom build 30mm axle whit the possiblity to add a drive shaft on it. working on a Inventor 3D plan to show how it fill fit. stay tuned :)
and for the crash bar : yes it is , but imo i dont think a 5 point grade 8 bolt on gonna break. the frame gonna twist/break before bolt cut off.
