Engine kill switch operation, proper wiring of safety interlocks (e.g., side stand switch if equipped on the motorcycle).
Protective Equipment:
Manual will implicitly recommend appropriate personal protective equipment (PPE) for mechanics working on the engine (gloves, eye protection).
Infotainment System:
Not applicable at the engine level. Infotainment systems are part of the motorcycle's electrical and chassis components.
Engine Management System:
Electronic Fuel Injection (EFI) with engine control unit (ECU) for managing fuel delivery, ignition timing, and other engine parameters.
