I used to own a Honda Nighthawk CB750. It wasn't going to break the sound barrier, but it was not slow and it handled like a sport bike. I named her Grace, had her painted a gorgeous dark blue/green, painted the rims black and put a pair of clubman's on her.
In April 2013, I got onto her with a backpack full of clothes, a laptop and a camera, and I rode her from Albany NY to Key West, FL, in 4 days, all by myself. I kid you not, my ass was so sore that I had to stand in all of the bars and beaches for the first 2 days after arriving. It was easily the most fun I've ever had. I averaged 100mph the whole way down, weaved cars like threading a needle. No cops gave me a hard time.
Three weeks after I got home, I dumped her on a turn, slid 100 ft on my back and came within 15ft of a gaurd rail. I still have the road rash on my right arm. I will not sit on a motorcycle again, not for fear of riding, but because I know I can't trust myself to go slow.
