Honda Speedometer Cable replacement decoration

Have you chopped your motorcycle but haven't had the time to replace that annoying open hole where your speedometer cable used to go?? Who needs a speed cable anyway when your chopping around town! Very specific application for 90's era Honda Shadow 600's and 70's era Honda CB 750s. Designed to be a push fit, I tested these going about 90mph and it stayed in place. I did use a bit of CA glue to keep it on the spindle.
