Engine Management System:

Advanced for its era, likely with programmable ECU mapping for performance optimization. The manual will detail its functions and diagnostic capabilities.

🔧 Maintenance

Oil Change Interval:

Every 7,500 km (4,500 miles) or annually, whichever comes first. (Refer to manual for precise interval).

Desmo Service Interval:

Typically every 12,000 km (7,500 miles) for valve clearance check and adjustment. (Crucial for desmodromic engines, refer to manual for exact interval).

Timing Belt Interval:

Every 24,000 km (15,000 miles) or 2 years, whichever comes first. (Critical due to potential for severe engine damage if belt fails).

Engine Oil Spec:

Refer to manual; typically a premium synthetic motorcycle oil like SAE 10W-40 or 15W-50 (e.g., Motul 7100 or 300V).

Coolant Spec:

Ethylene glycol-based coolant with corrosion inhibitors. Ratio and type specified in manual.
