Fuel Type:
Unleaded Petrol (Gasoline).
Ignition Type:
CDI (Capacitor Discharge Ignition) with a magneto.
Safety Standards:
Designed to meet Indian safety standards for two-wheelers of its era. No formal crash ratings like modern cars.
Braking Setup:
Drum brakes front and rear.
Lighting:
Halogen headlight, taillight, brake light, and turn indicators for visibility.
Frame Construction:
Steel frame providing structural integrity.
Infotainment System:
Basic instrumentation: speedometer, odometer, fuel gauge (if applicable), indicator lights. No advanced infotainment systems.
Driver Assistance Features:
None. Focus on mechanical reliability and rider input.
Connectivity Options:
None.
Oil Change Interval:
Every 3000-4000 km or 6 months, whichever comes first. Specific oil type to be confirmed in manual.
Spark Plug Replacement:
Typically every 6000-8000 km. Correct spark plug type (e.g., Champion, Bosch) would be specified.
Air Filter Cleaning:
Regular checks, cleaning/replacement every 2000-3000 km or as needed based on operating conditions.
Brake Adjustment:
Periodic inspection and adjustment of brake shoe clearance.
Engine Oil Type:
Typically a 2T (two-stroke) engine oil, mixed with petrol at a specified ratio (e.g., 1:20 or 1:30), or a dedicated oil injection system would require specific 2T oil (e.g., Bajaj Premium 2T oil, API TC).
Transmission Oil:
While many scooters of this era have a gearbox without separate transmission oil, if present, it would be a specific gear oil like SAE 80W/90. However, most 2-stroke geared scooters use a small amount of gear oil for the gearbox lubrication.
Carburetor Fouling:
Common in 2-stroke engines due to carbon buildup; requires periodic cleaning and tuning.
Electrical Connections:
Corrosion or loosening of electrical connectors can lead to intermittent issues with lights, horn, or ignition.
Brake Shoe Wear:
Regular inspection and replacement of worn brake shoes are crucial for safety.
Vibration And Noise:
Can occur with age due to worn engine mounts, suspension components, or exhaust leaks.
Bajaj History:
Bajaj Auto is one of India's leading two-wheeler manufacturers, with a long history of producing reliable and affordable vehicles.
Chetak Legacy:
The Chetak nameplate has a significant heritage in India, originally associated with Vespa-licensed scooters produced by Bajaj. The 2004 model represents a modern iteration of this popular platform, often incorporating stylistic and mechanical updates.
