Those of you who own, or have owned, a Harley-Davidson Sportster
don't need us to tell you that for the past 47 years, Sportsters have
delivered on hot-rod performance, versatility, and bare-knuckle
styling. The four models in the new 2004 lineup take these
attributes to a whole new level with a redesigned Sportster Evolution
V-Twin engine that is rubber mounted in a brand new, sleeker frame.
The lineup is comprised of the classic XL883 Sportster 883, the
XL883C Sportster 883 Custom, the XL 1200C Sportster 1200 Custom, and
the new XL 1200R Sportster 1200 Roadster.
The lineup boasts a new twin-cradle steel frame and swingarm
design that supports the powertrain using three stabilizer links.
This results in an engine/frame partnership that is 26% stiffer than
previous Sportster models and a more comfortable ride through less
vibration. Lower seat height (26.3") and a narrower frame
accommodate the shorter rider offering improved comfort and handling.
The battery and oil tank are located behind symmetrical covers
and feature a new push-button dipstick. Engine cooling is improved
with new cylinders, heads with larger fins, and new internal oil jets
that cool the pistons. High-performance cams add torque to the new
XL Evolution 1200, which also benefits from high-flow heads with an
oil drain-back feature, and lighter pistons with a high-speed ring
pack to extend top-end life.
Restyling on the XL Evolution engines includes a new contour on
the air-cleaner cover, and a new location for the exhaust cross-over
pipe, which now resides behind the mufflers to provide an
unobstructed view of the engine.
The XL Evolution 1200 engine is rated at 70 peak horsepower at
6000 rpm and 79 ft-lbs of torque at 3500 rpm, an increase of more
than 15% over the previous 1200 powerplant. The XL Evolution 883
makes 53 peak horsepower at 6000 rpm and 51 ft-lbs of torque at 4300
rpm (US figures).
Rounding out the new package is a wider rear tire, from 130mm to
150mm, a new braking system designed to reduce initial lever effort,
and a reduced handgrip diameter (from 1 1/4" to 1 1/8"), shortening
the reach to the control levers. Retention of the distinctive
"peanut" profile of the traditional Sportster 883 and Sportster 1200
Roadster was accomplished even though the tank capacity was increased
from 3.3 gallons to an ample 4.5 gallons, delivering about 30% more
range - always a good thing!
