140 Had a girlfriend that owned a Porsch 911 back in the early 70's. The speedo went up to 180 IIRC so me and a buddy took it for a joy ride one night but I couldn't get it over 140. I was pretty disappointed so I dumped her ass.
Went 114 on a MC once,,,, that was some scary chit. All I could think about was the front tire blowing out. Not near as fun as you would think.
