Not sure if there has already been threads or an area for this but I am sure some others have an interest in it like me...
I'm always curious what parts are interchangeable or "direct/semi-direct" bolt on from, not just Honda's but other makes and models.
I'd love to see a thread of parts people have used from other bikes on their SOHC4's with little to no modification inorder to get them to work.
For example, I've considered finding a pair of rims off an old Ninja or VTR but I would have no idea of the modifications involved to fit them on my CB550F without buying the wheels and trying them out.
Shocks, wheels, forks, clip ons, etc...
Or a tach/speedo cluster or any other electrical component that doesnt involve complete re-wiring.

The only item I've used so far off a non-Honda was a 1979 KZ-750 tail light. Not a direct bolt on for mounting, because I recessed it into my custom seat/tail...... but the 3 wires matched up perfectly to my CB550F taillight wiring.
