I've got a Rocket III and nothing compares. I also had an M109R for 5 years before I got the rocket. Much higher quality machine. Great balance. Has more power then you ever need, especially with hauling a passenger, its effortless.
Was just going to suggest this bike. Saw it yesterday, what a monster.
