Fuel System:
Carburetor (likely for these models) or fuel injection system diagnostics, cleaning, adjustment, and component replacement; fuel pump, filter, lines.
Electrical System:
Wiring diagrams, component testing, troubleshooting of starter motor, alternator, battery, ignition coil, regulators, lights, horn, instruments.
Maintenance:
Scheduled maintenance intervals, oil changes, filter replacements, spark plug service, brake fluid flush, coolant checks, drive belt inspection/replacement.
Troubleshooting:
Systematic diagnostic procedures for common faults and symptoms, including no-start conditions, poor performance, electrical issues, braking problems.
Repair Operations:
Step-by-step instructions for component replacement and repair, torque specifications, special tool requirements.
Depth:
Comprehensive, covering everything from basic owner maintenance to advanced engine rebuilds and electrical diagnostics. Suitable for professional technicians and experienced DIY enthusiasts.
Type:
Four-stroke, single-cylinder, OHC (likely air-cooled for 125/150, potentially liquid-cooled for 200 variant).
Displacement:
125cc, 150cc, 200cc (specific bore and stroke values would be detailed in the manual).
Horsepower:
Estimated 10-15 HP for 125/150cc, 15-20 HP for 200cc, depending on specific tuning and emission standards. Exact figures in manual.
Torque:
Torque figures would be specific to each displacement and readily available in the manual.
Fuel Delivery:
Likely carburetion (e.g., Mikuni or Keihin) for most variants, but the 200cc might feature electronic fuel injection (EFI) depending on market and year. Manual will clarify.
Wheelbase:
Specific dimensions would be provided in the manual, generally around 1300-1400 mm for this class.
Dry Weight:
Typically in the range of 110-130 kg, depending on displacement. Exact figures in manual.
Payload Capacity:
Sufficient for rider and passenger, with luggage capacity under the seat. Specific weight limits in manual.
Crash Test Results:
Motorcycles and scooters of this era were not typically subjected to standardized crash testing in the same way as automobiles. Safety features focus on operational safety.
Braking System:
Front disc brake, rear drum or disc brake (depending on model variant). ABS was uncommon in this segment at the time but may be present on later or higher-spec models. Manual will detail.
Lighting:
Headlight, taillight, brake light, turn signals, offering visibility during operation.
Instrument Cluster:
Analog/digital combination instrument cluster typically including speedometer, tachometer (for 150/200), fuel gauge, odometer, trip meter, and warning lights.
ABS:
Anti-lock Braking System was an option or standard on some later/higher-end models. Manual will confirm availability for specific variants.
Charging Ports:
Some models may have featured a 12V accessory socket for charging devices. Not standard on all.
Oil Change:
Typically every 3,000-5,000 km or annually, whichever comes first. Specific interval in manual.
Spark Plug Replacement:
Generally recommended every 5,000-10,000 km. Specific type and gap in manual.
Air Filter Cleaning Replacement:
Check every 3,000 km, clean/replace as needed or at scheduled intervals (e.g., 6,000-10,000 km).
Engine Oil:
Likely SAE 10W-40 or 15W-50, JASO MA certified motorcycle oil. Manual will specify exact viscosity and API classification.
Brake Fluid:
DOT 4 is most common. Manual will specify.
Coolant:
If liquid-cooled, a mixture of ethylene glycol-based antifreeze and distilled water (typically 50/50). Manual will specify.
Common Wear Items:
CVT belt and roller wear, suspension bushings, brake pads/discs, exhaust system corrosion, electrical connections.
Potential Failures:
Water pump seal (if liquid-cooled), carburetor jetting issues, voltage regulator failure. Manual will provide diagnostic steps.
Derbi Legacy:
Derbi is a Spanish manufacturer with a long history in motorcycles, particularly known for its smaller displacement and performance-oriented models, including scooters and off-road bikes.
Boulevard Lineage:
The Boulevard was Derbi's offering in the popular maxi-scooter segment, designed to provide comfortable and efficient urban and suburban transportation. It evolved through various engine sizes to meet market demand.
Manufacturing Location:
Primarily manufactured in Spain by Derbi (part of the Piaggio Group during this period).
