Honda CB815 cafe-racer. Occasional view.

The view I had pleasure to look at, relaxing in chair with legs stretched after day of work and some ride during which I spontaneously did the ton couple of times. Not that I intended to do it, just couldn’t resist the wish to twist the throttle bit harder.

    Hi Robak,

    CBX750 RC17 and CB750 Seven Fifty RC42 have 67x53mm of bore x stroke. That means 747ccm

    However, I used 70mm pistons and alternative connecting rods to keep original compression ratio. Bore x stroke 70×53 gives 815ccm.

    Hi Aaron,

    It’s Honda CX500 tank. However it does not fit as it is. Here is how I modified mounts on frame to fit tank:
