Im sure you went past 65mph easily because I know there are a few areas where my stock KA 240sx went past that and I didnt redline it much. But for me and my skill set as a driver 65mph was the average max speed. I know the Killboy.com photographer with the silver evo hits 80mph alot of that road.

Yeah I would probably get killed on the skyway unless I had some aero enhancements to my car. Its not that it gets unstable but it becomes very easy to break traction loose in certain situations with speeds that high. I dont know how it is on a bike but my a-piller was constantly in my way especially on switch backs and my field of vision wasnt as far as I would of liked I had to constantly look out my door window to follow the road to make sure no one was heading my way. But nothing beats those twisty roads up in that area in terms of excitment.
