Harley Davidson Sportster S RH1250S 2024 Service Manual

Harley's own confirmed product copy calls this "wickedly quick, impressively nimble, and way too much fun to ride" — a genuine departure from the traditional pushrod Sportster architecture this bike replaced, dropping the classic Evolution V-twin entirely in favor of a thoroughly modern liquid-cooled unit.

Power comes from the Revolution Max 1250T, a liquid-cooled 60-degree V-twin, DOHC with variable valve timing, delivering a claimed 121 hp and 94 lb-ft of torque, run through a 6-speed transmission with a slip/assist clutch and belt final drive. The chassis uses a 43mm inverted fork with compression, rebound, and spring preload adjustability on aluminum triple clamps, paired with a linkage-mounted, piggyback monoshock offering the same three-way adjustability.

Standard equipment includes a 4-inch TFT display showing speedometer, gear, odometer, fuel level, clock, trip, ambient temperature, low-temperature alert, side-stand-down alert, tip-over alert, cruise control, range, and tachometer, with Bluetooth phone pairing for calls and music. A three-phase, 45-amp electrical system (300 watts at idle, up to 585 watts at 2,250 rpm) powers the whole setup.

Confirmed dimensions list an 89.4-inch length, 33.1-inch width, a genuinely low 30.1-inch unladen seat height, 4.1 inches of ground clearance, a 30-degree rake with 5.8 inches of trail, and a 59.8-inch wheelbase. Fuel capacity comes in at a compact 3.1 gallons (0.8-gallon reserve), with 4.75 quarts of oil and 0.6 quarts of coolant. Shipped weight is 487 lbs, rising to 502 lbs in running order, riding on 160/70TR17 front and 180/70R16 rear Dunlop Harley-Davidson Series radial tires.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2024 Sportster S RH1250S running the way it was built to.
