Positioning:
The Harley-Davidson XL1200N Sportster Nightster (2008) represented a stylish, urban-focused cruiser variant within the iconic Sportster lineup, appealing to riders seeking a classic look with modern performance.
Competitors:
Competed against other American V-twin cruisers and Japanese retros in its displacement class, such as certain models from Indian Motorcycle, Victory Motorcycles, and various Japanese manufacturers like Yamaha (e.g., Star Bolt), Honda (e.g., Shadow series), and Kawasaki (e.g., Vulcan series).
Nightster Distinction:
The 'N' designation for Nightster signified a darker, more minimalist aesthetic compared to other Sportster models, often featuring blacked-out components, lowered suspension, and a bobbed rear fender for a custom look.

Valve Train:
Pushrod-actuated overhead valves, 2 valves per cylinder
Horsepower Estimated:
Approximately 65-70 HP (figures vary, not officially stated by H-D for this era)
Torque Peak:
Approximately 70-75 ft-lbs @ 3200 RPM (figures vary)
Fuel Delivery:
Electronic Sequential Port Fuel Injection (ESPFI) for 2008 models. (Note: Some earlier or later models might have used carburetors, but 2008 XL1200N is typically EFI).
Fuel Tank Capacity:
3.3 gallons (12.5 L)
Oil Capacity:
Approximately 3.0 US quarts (2.8 L) with filter change.
Oil Type Specification:
Harley-Davidson Genuine V-Twin 20W-50 or equivalent API CI-4, JASO DH-1 specification oil.
Infotainment System:
Basic analogue instrumentation: speedometer, tachometer (optional depending on specific trim), odometer, trip meter, and indicator lights. No advanced infotainment systems were standard on this model.
Driver Assistance Features:
No electronic driver assistance features such as ABS or traction control were standard on the 2008 XL1200N. ABS was an optional factory fitment for some Harley-Davidson models of this era, but unlikely standard on the Nightster.

Initial Service:
Typically around 1,000 miles (1,600 km) for the first major service, including oil change, filter replacement, and thorough inspection. The manual will detail specific intervals.
Regular Maintenance:
Intervals for oil changes (e.g., every 5,000 miles or annually), belt inspection/adjustment (e.g., every 5,000 miles), brake fluid flush (e.g., every 2 years), spark plug replacement (e.g., every 10,000-15,000 miles). Specifics are in the manual.
Engine Oil Viscosity:
20W-50
Primary Chain Case Oil:
Harley-Davidson primary chaincase lubricant or an equivalent manual transmission fluid meeting specific H-D specifications.
Transmission Oil:
Harley-Davidson transmission oil or an equivalent SAE 80W-90 gear oil meeting specific H-D specifications.
Brake Fluid:
DOT 4 hydraulic brake fluid.
Common Wear Items:
Clutch plates, brake pads, tires, drive belt, wheel bearings, fork seals, and battery are common wear items requiring periodic inspection and replacement.
Potential Electrical:
Early EFI systems or charging system components (regulator/rectifier) can sometimes be a source of issues, though the Evolution engine is generally robust.
Potential Engine:
Carbon buildup in heads, exhaust leaks at head pipes, and occasional oil leaks at seals are not uncommon with high mileage on Evolution engines.
