I don't own a motorcycle, or even a bicycle. 4 months post-op, I found myself in a hotel with nothing to do. There was a bicycle rental out front, so I gave it a try. I had zero problem, found it exhilarating instead. My ride lasted a little over an hour before the mosquitos chased me back inside.
Everyone heals at their own rate - I had a lot of post-op problems, and didn't think it would ever get better. For me, 3 months was more or less the turning point, and everything was normal after that.
Good luck!
