Paul, can you confirm that it is the tape on this link...3M 680-85...Scotchlite Black.
Alex, I can't confirm that. I told the safety supply store that I wanted 3M High Intensity Grade Prismatic Reflective Sheeting - White 3930 and they cut four feet off a roll that was about 5" wide. They told me that it was 3M High Intensity Grade Prismatic Reflective Sheeting - White 3930. The tape colour is silver and the back simply says 3M Relective Sheeting. It certainly is a major improvement on what GIVI supplied.
Besides the reflective tape on the bike, I have silver (white reflecting) tape down the sides of my riding suit plus a couple of wide lime green stripes on my vest. My wife used to be worried about my being seen at night until one night when she followed me on the 401. When she finally passed me, she realized that I was also very visible from the front with the triangular arrangement of lights.
Many decades ago, I spent a year working in the local hospital's ORs. I have seen what damaged riders look like. I try to avoid visiting that location, although a couple of Sunday mornings ago, I did have a van make a left turn from a side street RIGHT in front of me. Brake covering, panic braking, brake release and a last second swerve around the rear end saved my hide.
Once again Alex thank you for sharing the GIVI tip.
