None standard. Aftermarket options may exist for audio systems or GPS.
Initial Service:
500 miles (800 km) - typically includes oil and filter change, primary chain adjustment, chassis lubrication, and inspection.
Subsequent Service:
Every 5,000 miles (8,000 km) or annually, whichever comes first (includes oil change, filter, spark plugs, belt inspection, brake inspection, etc.). Specific intervals for other items like fork oil, transmission fluid, and differential oil are detailed in the manual.
Engine Oil Type:
Harley-Davidson Syn3 (20W-50 synthetic) or equivalent premium quality motorcycle oil meeting Harley-Davidson specifications (e.g., API SG, SH, SJ, SL).
Engine Oil Capacity:

Cam Chain Tensioners:
Early Evolution engines had spring-loaded cam chain tensioners prone to wear. While 2005 models might have received updates, this is a common area for inspection and potential upgrade to hydraulic tensioners for longevity.
Carburetor Adjustment:
The Keihin CV carburetor can sometimes require periodic adjustment or cleaning to maintain optimal performance and idle stability.
Belt Drive Tension:
Proper belt tension is crucial for longevity; over-tensioning can damage bearings, while under-tensioning can cause slippage.
Harley Davidson Legacy:
Harley-Davidson, founded in 1903, is an iconic American motorcycle manufacturer renowned for its V-twin engines and cruiser/touring motorcycles.
Sportster Lineage:
The Sportster line dates back to 1957, evolving significantly over the decades. The Evolution engine was introduced in 1986, offering improved performance and reliability over earlier Ironhead engines. The 2005 models represent a mature iteration of the Evo Sportster platform.
