140 on my Kawasaki Vulcan 2000 down the Pacific Coast Highway (Hwy 1), just after coming out of the twisties, north of San Simeon. I'd been jammed up with RV's forever and when we broke into open road, I took off. Was only doing about 80 when a Miata blew by me like I was sitting still. It was late in the day, most of the tourists were off the road, so I thought, why not? Using the Miata as my radar detector, I opened it up and gained ground. When he saw me coming , he just went faster, a perfect invitation to do the same. The road has long wide turns, with slow undilating ups and downs, so not too hard to keep it on the road.
I normally would never go that fast, but I had never had this bike opened up and it just seemed like the perfect time. We ran this way for about 15 miles, at which time I never went slower than 110.
What a ride! and I'll never do it again.
