Variations On The Theme
In its 50 years of existence, the longest-selling (and most affordable) Harley has donned literally dozens of guises for the Motor Company. The original 53-cubic-inch overhead valve XL Sportster begat the more muscular XLCH and the racing XLR and later spawned even more variations on the theme. For 2008, the 883 comes in three flavors, so you're pretty much assured of getting what you want.
XL 883 Sportster 883
The so-called "beginner" Harley-Davidson is probably the most recognizable. From the 3.3-gallon "peanut" fuel tank to the staggered dual exhaust, the XL 883 is chock-full of traditional cues. For 2008, the list includes a rubber-mounted Evolution 883cc engine (powdercoated silver and polished); 13-spoke cast wheels wearing 19-inch front and 16-inch rear tires; low-rise handlebar; solo seat; mid-mount foot controls; and, a Smart Security System option.

XL 883L Sportster 883 Low
The 883 Low is probably the least intimidating option, thanks to a reduced-reach (read: narrow) solo seat jammed just 25.3 inches off the pavement. It gets the same rubber-mounted, powdercoated Evolution engine but tweaks the suspension both front and rear to drop the travel a full 2 inches lower than the standard 883 Sportster and spreads out touring-style handlebars for an easier reach.
Running gear is much the same as its siblings, with a 19-inch front and 16-inch rear tire, mid-mount foot controls, and a 3.3-gallon fuel tank, but the Sportster Low swaps in the low-profile rear shocks and front forks and an easier-to-reach sidestand.

XL 883C Sportster 883 Custom
If you want real attitude, the Sportster 883 Custom's 21-inch laced front wheel, 4.5-gallon fuel tank, two-up seat and forward controls might be more up your alley. The rear gets slammed via a set of low-profile shocks riding over a cast rear wheel, but otherwise it's the standard XL 883 formula: rubber-mounted Evolution mill; staggered dual exhaust; and, optional Smart Security System.
