Crash Safety:
Motorcycles are not typically subjected to formal crash safety ratings like automobiles. Safety is primarily dependent on rider skill and adherence to road safety regulations.
Braking System:
High-performance dual front disc brakes (e.g., 320mm diameter) with radial-mount calipers, and a single rear disc brake (e.g., 220mm diameter). ABS was an optional feature on some variants.
Lighting:
Halogen headlights, LED taillight, and integrated turn signals.
Chassis Design:
Robust twin-spar aluminum frame for rigidity and stability.
Oil Change:
Typically every 3,000-5,000 km (1,800-3,000 miles) or annually, whichever comes first. Refer to manual for precise interval.
Valve Check:
Recommended around 10,000-15,000 km (6,000-9,000 miles). Crucial for V-twin performance.
Chain Adjustment:
Check and adjust every 1,000 km (600 miles), or as needed based on slack.
Engine Oil:
High-quality Synthetic Motorcycle Oil, SAE 10W-40 or 15W-50 (check manual for specific viscosity and API/JASO rating, e.g., JASO MA/MA2).
Coolant:
Ethylene Glycol based antifreeze/coolant, typically a 50/50 mix with distilled water. Specific type may be specified by Aprilia.
Brake Fluid:
DOT 4 or DOT 5.1 brake fluid (ensure compatibility with seals). Refer to manual for exact specification.
Clutch Fluid:
DOT 4 brake fluid (if hydraulically actuated). Refer to manual for exact specification.
Electrical Gremlins:
Older Italian bikes can sometimes develop electrical issues; thorough inspection of wiring harnesses, grounds, and connectors is recommended. The manual's electrical troubleshooting section is invaluable.
Fuel Injection Control Unit (Ficu):
Early FI systems could be sensitive; proper maintenance and clean fuel are essential. The manual will detail diagnostic procedures for the ECU.
Cam Chain Tensioner:
Automatic cam chain tensioners can wear out, leading to a rattling noise. Replacement is a common maintenance item.
