Connectivity Features:
N/A (No Bluetooth, USB, or smartphone integration).
Oil Change Interval:
Typically every 7,500-10,000 km (4,500-6,000 miles) or annually, whichever comes first. Consult a service manual for precise intervals.
Desmo Service Interval:
Major Desmodromic valve clearance check and adjustment every 24,000 km (15,000 miles). This is a critical and specialized service.
Belt Replacement Interval:
Timing belts require replacement typically every 2 years or 24,000 km (15,000 miles), whichever comes first, due to age and wear.
Engine Oil Type:
