Configuration:
Single-cylinder, 2-stroke
Displacement:
Approximately 193cc (exact may vary slightly by specific sub-model or year).
Bore X Stroke:
Specifics would be detailed in the manual, typically around 62.5 mm x 65 mm.
Cooling Method:
Liquid-cooled
Lubrication:
Pre-mix or Autolube (depending on specific variant within the production run).
Horsepower:
Estimated around 35-40 HP, with variations based on tuning and year.

Carburetor Type:
Typically a Keihin PWK series carburetor (e.g., PWK 38).
Fuel Type:
Unleaded gasoline with appropriate octane rating (91-98 RON/87-93 AKI).
Fuel Mixture:
If pre-mix, the recommended oil-to-fuel ratio (e.g., 30:1 or 40:1) will be specified.
Oil Change Engine:
Frequent oil changes recommended for 2-stroke engines, typically every 15-20 hours of riding or as specified in the manual.
Air Filter Cleaning:
Recommended after every few rides or in dusty conditions.
Spark Plug Check:
Regular inspection and cleaning/replacement as needed, typically every 20-40 hours.
Chain Maintenance:
Lubrication and tension adjustment recommended every 5-10 hours of riding.
Transmission Oil:
Specific gear oil (e.g., SAE 75W/80W or similar) and capacity will be detailed in the manual.
Brake Fluid:
DOT 3 or DOT 4 brake fluid (refer to manual for specific type).
Coolant:
