Glad to see you are still on the road. In Bogota there is area of a couple city blocks that is nothing but motorcycle shops, I would start there. Sorry I can't recall the street name, but any biker should know where it is. They mostly cater to local smaller bikes, but worth a shot.
If you can go to Medellin, on Calle 10, near Carrera 30 something, there are a bunch of high end bike shops, I have no doubt you would find something there.
I am recovering from a broken collarbone I got in a pedal bike wreck a few weeks ago. I had surgery 10 days ago, and now have a bunch of metal in my shoulder. The good news is that I bought a new XR1200 Sportster to cheer myself up. It'll be another few weeks before I can ride it, though.
Stay on a motorcycle, where you're safe,
