According to HD, the Sportster has a 28 inch seat height, 4.5 gallons in the tank, 55 ft lbs of torque, and weighs in at 590 lbs wet. It has a brutally simple instrument panel, speedometer and indicator lights only, and Harley's classic turn signal controls on both handlebars (rather than controlling them both with one thumb.) It also has the look that hasn't changed much in the fifty years that this model has been in production.
But, how does it ride, you eagerly ask. It's heavier than any production sportbike and it makes that fact known, but it also has a low center of gravity in comparison so it is still easy to stand up and hold. Twisting the throttle yields gobs of low end power, but even though it doesn't have the eyeball popping acceleration I found on Buell's 1125, it feels like you could use it to pull tree stumps out of the ground. The high handle bars and kicked out feet made for a very relaxed feeling on the straights but were less than confidence inspiring in turns. I suspect some one more used to the cruiser style would feel the same way if they got on a sportbike though.
Overall, the fit and finish of the motorcycle was impeccable and it was very comfortable, the throttle response was predictable and the clutch pull light and smooth. It would make a very nice second bike for someone interested in that style, but the weight and torque put it a little beyond what I would typically recommend that a new rider start on, even though I know several people who have gone this route.
