It's a 96 cubic inch motor... I believe that's about 1584 cc. I decided that Harley's are the trucks of the motorcycle world with the low end torque. She tried to buck me off a couple times today while taming the beast. Luckily, my fingernails were able to dig into the rubbery handgrips which kept me from flying off the back. Of course, I'm a much better rider now than I was about 8 hours ago. I think the ride quality is great. Dyna's ride much better than the Sportster's. I've got a road trip planned for Friday, Saturday and Sunday. We'll see what I say about the ride after that. I have feeling that I'm just going to love it more.
