We rode to Leakey together in the rain. I was on the stock Classic when I had just gotten it. She was horribly slow at that time. Probably not making over 110 hp. Not saying that a SD can't outrun the stocker, but I do have a slightly modified Roadster that should give it a little competition in a straight line. So far there's been a couple of GSXR 1000s, a BMW SS1000RR, and a V4 Panagali that have fallen behind on straight line runs. Betty runs ok for a big fat cruiser, with a fat old man riding her.
