Recently picked up a bunch of parts for a CB750 cafe racer build. While cleaning up the frame and tank, I realized the tank I have (CX500) looks way too bulky for the frame and sits pretty high.
I know I could make it fit with fabrication, but I’m not loving the proportions anyway.
A couple questions:
• What gas tanks are known to fit a CB750 frame with minimal fabrication? Are CB750 tanks really my only clean option, or are there other good swaps (CB550, CB500, etc.)?
• Has anyone here actually run a CX500 tank on a CB750 frame? If so, what did you have to modify (mounts, tunnel, seat alignment), and were you happy with the final look?
For context: I’m going for a slimmer, more classic cafe racer profile, not a bulky/brat style.
Appreciate any advice or build pics, thanks ✌️
