Hi, I ve been searching for the triple tree geometry measurements for a 79. Does any one knows offset, rake and fork span?

Thanks.

Ramon

The triple tree itself has no rake. The rake is in the frame. It is 27.5°.
The fork span is 195mm and the offset is 60mm. These are not official Honda numbers but dimensions taken from a part to be used in my front end geometry calculator. They worked fine.

Hi EMS, thanks for the answer.

Yesterday I did a very quick measurement, nothing precise, and it seem the offset is 40 mm instead of 60 mm. I measured from the center of the stem to the imaginary centerline of the forks. Is this right?

Best.

Yes, Ramon, that was a typo. It is 40mm. Sorry.
