Oi Gustavo,
I recently saw your post from May 2019 regarding your book "the Cafe Racer Bible". I love your work and your novel rear suspension. I'd like to know if the rear suspension linkage you've designed and detailed in your book/CAD drawings is suitable for use on a K75? I have a 1995 K75 that's the perfect (ugly) donor bike and would like to use your suspension approach in an upcoming build.
Also, if possible I'd like to know what geometry is included in the 3D plans you mentioned and if any of the CAD files work for a K75!
Thanks,
Russell
