I also ordered highway bars from Vicente, a member of an online
Kawasaki Vulcan forum. These bars are custom made in a shop in Mexico. Then Vicente checks them for correct fit, has them chromed, and then ships them from his home in Texas. I received the bars in a well-packed box. As Vicente described, the bars were very sturdy and the chrome was high-quality. The included directions for installing the bars were great, including numerous photos.
When I installed the top black steel plate which the bars attached to, the holes in the plate were about 1/8" too far apart to match the screw holes on my frame. I had to elongate the holes on the black steel plate with a drill press. (Vicente tests them for fit before shipping, so we are not sure why my bike was off a little.) I also added a few extra washers to each end of the u-clamps. Other than that, the installation was straightforward.
I am very happy with the highway bars and tell anyone that cares about my custom-made bars that spanned 2 countries in being made. I would recommend them to anyone with a Vulcan 500 who wants bars.
