After this winter, I've got plans for the motor in my '96 Ultra SP, so I'll be needing a new sled next winter. I'm considering an 800 xcr because I love the triples or a 900 fusion for the creature comforts of a newer sled. I'd like to hear some of the pluses and minus' for each, if'n ya don't mind. Just for giggles, how much of a speed difference is there from say the ultra to the 800 to the 900. Thanks
