performance rating for the 883 with 1200 up grade kit. 68.9 hp and 67.8 foot pounds of torque.

904cc - 70 - 78 HP. 62 - 66 ft. lbs.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
