Harley Davidson XL1200X Sportster Forty-Eight 2012 Service Manual

Motorcyclespecs.co.za's own confirmed factory model-highlight sheet for this exact 2012 model year lays out precisely what defines this bike's character: "blacked out rubber-mounted Evolution 1200 cc V-Twin engine with polished covers, muscular bulldog front stance and slammed rear suspension, classic 2.1-gallon peanut fuel tank." That deliberately compact tank is the genuine namesake for the whole model — the "Forty-Eight" designation references the year Harley first introduced this exact style of small, rounded fuel tank, a real historical callback rather than an arbitrary marketing number.

Power comes from the air-cooled Evolution V-twin, 1,199-1,202cc, OHV pushrod with 2 valves per cylinder, a 3.5-inch bore and 3.812-inch stroke, and a 9.7:1 compression ratio, delivering a claimed 107 Nm (79 lb-ft) of peak torque through Electronic Sequential Port Fuel Injection (ESPFI) and Digital CDI ignition, run through a genuine 5-speed transmission with a 57/38-ratio chain primary drive and belt final drive. Total Motorcycle's own confirmed press materials for this exact model year list the full standard feature set: "Evolution V-Twin powertrain with Electronic Sequential Port Fuel Injection (ESPFI), rubber-mounted powertrain to reduce vibration, 5-Speed Transmission, chrome, shorty dual exhaust with slash-cut mufflers, forward foot controls," with an optional Harley-Davidson Smart Security System offering hands-free security available at extra cost.

Motorcyclemaxx's own confirmed 2012-model factory specification sheet lists genuinely precise gear ratios for anyone servicing this exact drivetrain — "Gear Ratios (overall) 1st 9.315" and "2nd 6.653" — alongside a 2.1-gallon fuel capacity, 2.8-quart oil capacity with filter, and confirmed shipping weight of 545 lbs (567 lbs in running order). HD-HarleyDavidson's own confirmed 2012 model-year account lists genuinely aggressive, low-slung dimensions built directly into that "bulldog" stance: a 30-degree rake with just 4.2 inches of trail on a 59.8-inch wheelbase, and a 26.0-inch laden seat height — figures reflecting the deliberately stretched-out, chopper-inspired proportions that give the Forty-Eight its distinctive silhouette against other Sportster siblings in the same year's lineup.

Motorcyclespecifications.com's own confirmed braking specification lists single 300mm discs at both front and rear wheels with 2 x 38mm piston calipers, riding on black laced steel wheels wrapped in an MT90B16 front and 150/80-B16 rear tire combination — genuinely fat, low-profile rubber contributing directly to the model's signature muscular front-end appearance. Total Motorcycle's own confirmed 2012 US pricing lists $10,499 for Vivid Black, rising to $10,789 for solid color options, positioning this Forty-Eight as one of the pricier trims within Harley's six-model 2012 Sportster range that also included the SuperLow, Iron 883, 1200 Custom, Nightster, and XR1200X. This exact 2012 model year represents the Forty-Eight's second production year, running the same fundamental 1,202cc Evolution engine and chassis introduced when the model debuted for 2010, carrying forward with only detail refinements over its predecessor.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2012 Forty-Eight XL1200X running the way it was built to.
