Yeah, 172 mph or something sticks in my head as a "design" top speed. I'd think speedometer error is large at high speeds, and it's been 20 years ago, but I seem to remember that my 85 V65 Sabre's speedo top speed was in excess of 150 mph. Seems it was the about the same in 5th or 6th gear. I also remember my buddy's 1100 Katana kind of walking away from me at higher speeds, hehe.
