Defect
Certain motorcycles equipment with chrome-plated frames. Copper residue can remain in the tapped hole where the upper fork bridge attaches to the frames. Moisture can cause corrosion to occur between the copper residue and the aluminum frame. The stress of the connecting bolt attaching the upper fork to the frame could them decrease, leading to loosening, and ultimately, breakage of the bolt. If this happening, the dynamic stability of the motorcycle would be affected and a loss of control could occur.
Safety Risk
No risk description available.
Remedy
dealers will ream the hole in the frame head and install a helicoil thread insert and a new bolt.
