My bike's a 1985 Suzuki Katana 750. I first saw one in a Tamiya model catalog as a freshman in high school in '88 or so. It took until '99 to figure out that they weren't sold in the US, and to track one down in Canada, buy it and bring it back to Michigan.
As bought:
Phase 1 of modifications:
Phase 2 CAD work:
Parts:
New vs. old swingarms:
Finished-ish:
At the Blessing of the Bikes in Baldwin, MI last year.
