Engine Type:
Liquid-cooled, 2-stroke, single-cylinder
Displacement:
Approximately 193 cc (exact figure may vary slightly by sub-model or year)
Bore X Stroke:
Specifics would be detailed in the manual, typically around 66 x 57 mm
Compression Ratio:
Details in manual, generally higher for 2-stroke performance engines.
Cooling Method:
Liquid Cooling
Intake System:
Reed valve induction
Lubrication:
Premix (oil mixed with gasoline) or Autolube system (oil injection, depending on exact sub-model/year).
Horsepower Estimate:
Likely in the range of 35-45 HP, depending on tuning and year.
Torque Estimate:
Significant mid-range torque characteristic of 2-stroke off-road engines.
Carburetor Model:
Likely a Mikuni VM series (e.g., VM34 or VM38)
Fuel Type:
Unleaded gasoline (Octane rating specified in manual).
Oil Change Interval:
Refer to manual; typically every 10-15 hours of riding for gearbox oil.
Air Filter Cleaning:
Frequent cleaning/replacement recommended based on riding conditions, often every few rides.
Piston Ring Replacement:
Recommended at specific hour intervals (e.g., 50-100 hours) depending on riding style and engine condition, detailed in manual.
Top End Rebuild:
As needed based on performance, but factory recommendations exist (e.g., 100-200 hours for piston and rings).
Gearbox Oil Type:
Specific SAE grade transmission oil (e.g., SAE 10W/40 or SAE 75W/90) as per manual. Motorex is a common KTM recommendation.

Carburetor Performance:
Can be sensitive to altitude and temperature changes, requiring periodic jetting adjustments for optimal performance.
2-Stroke Maintenance:
Requires diligent attention to premix ratios and air filter maintenance due to the nature of 2-stroke engines.
