Engine Specifications
|
Primary Engine
|
Engine Description:
|
125cc liquid-cooled (likely) single-cylinder, two-stroke engine. Specific model variations within CX Apache, Free Style, Crono, and Freestyle families may have minor tuning or component differences.
|
Performance
|
Typical Power Output:
|
Approximately 15-20 HP (varies by specific model and tuning). Peak power typically achieved in the mid to upper RPM range characteristic of 2-stroke performance motorcycles.
|
Bore X Stroke:
|
Details will be within the manual, typically around 54mm x 54.5mm for a Gilera 125cc 2-stroke.
|
Engine Characteristics:
|
Typical of 2-stroke engines, known for a peaky power band requiring active gear selection and throttle control for optimal performance.
|
Fuel System
|
Carburetor Type:
|
Likely a Dell'Orto or Mikuni carburetor, typically in the 28-34mm range. Specific model and jetting details will be in the manual.
|
Carburetor Tuning Details:
|
Manual will include information on jetting, needle position, float height adjustment, idle speed settings, and air-fuel mixture for optimal performance across different altitudes and conditions.
|
Lubrication
|
Lubrication System:
|
Premix (fuel and oil mixed) or oil injection system. Manual will detail recommended oil types and ratios/settings.
|
Cooling
|
Cooling System:
|
Likely liquid-cooled due to the 'CX' designation often implying performance-oriented models, though air-cooled variants might exist. Manual will confirm.
|
Maintenance
|
Service Intervals
|
Oil Change Interval:
|
For 2-strokes, this primarily refers to gearbox oil changes. Typical interval: every 5,000-10,000 km or annually. Manual will specify precise interval and gearbox oil type/capacity.
|
Spark Plug Service:
|
Regular inspection and cleaning/replacement of spark plug, typically every 3,000-5,000 km, or as per manual recommendation. Manual will specify correct plug type and gap.
|
Top End Rebuild:
