Configuration:
Single-cylinder, four-stroke, liquid-cooled
Displacement:
125cc and 200cc variants
Typical Horsepower 125Cc:
Approximately 15-17 hp (varies by region and specific model revision)
Typical Horsepower 200Cc:
Approximately 20-25 hp (varies by region and specific model revision)
Bore X Stroke Approx 125Cc:
Likely around 54mm x 54.5mm (requires confirmation from specific model)
Bore X Stroke Approx 200Cc:
Likely around 64mm x 58mm (requires confirmation from specific model)
Induction:
Likely carburetor (e.g., Keihin CVK) or early fuel injection systems depending on the specific model and market. Manual will detail the specific system.
Fuel Type:
Unleaded gasoline, premium octane recommended.
Valve Actuation:
SOHC (Single Overhead Camshaft), likely 4 valves
Crash Test Data:
Motorcycles are not typically subjected to standardized crash testing like cars; safety is paramountly reliant on rider skill and vehicle design integrity.
Braking:
Disc brakes front and rear, hydraulic actuation. ABS was less common on entry-level models of this era but may be present on some variants.
Lighting:
Halogen or early LED headlights, tail lights, turn signals.
Frame Construction:
Steel trellis frame, renowned for stiffness and handling.
Ergonomics:
Designed for sporty riding posture, requiring rider input for stability and control.
Instrument Cluster:
Digital LCD displays are common, showing speed, RPM, gear indicator, fuel level, and trip meters. Some may have basic diagnostic readouts.
ABS:
Anti-lock Braking System (ABS) availability is model-dependent for this era. If present, the manual will cover its diagnostics.
Smartphone Integration:
Not applicable for models of this vintage. Connectivity features are absent.
Oil Change:
Typically every 5,000 - 7,500 km or annually, whichever comes first. Manual will specify exact interval and oil type.
Valve Clearance Check:
Typically around 10,000 - 15,000 km. Critical for performance and engine longevity.
Spark Plug Replacement:
Every 10,000 - 15,000 km, or as per manual recommendations.
Engine Oil Grade:
Likely a 10W-40 or 15W-50 semi-synthetic or fully synthetic motorcycle-specific oil. Manual will confirm API and JASO ratings.
Coolant Type:
Ethylene glycol-based coolant with anti-corrosion additives, typically a 50/50 mix with distilled water.
Brake Fluid:
DOT 4 hydraulic brake fluid is standard.
Fork Oil Grade:
Likely a 5W or 10W fork oil, with specific capacity per fork leg. Manual will detail.
Common Wear Items:
Clutch plates, chain and sprockets, fork seals, brake pads due to sporty nature and smaller displacement.
Potential Engine Concern:
Valve seat wear or camshaft issues can occur if valve clearances are not maintained, especially with aggressive riding.
Electrical Quirks:
Early models might experience some electrical gremlins if not properly maintained; wire connections and grounds are critical.
Origins:
KTM is an Austrian manufacturer with a strong heritage in off-road and racing motorcycles, known for its 'Ready to Race' philosophy.
Development Context:
The 125 and 200 Duke/RC models represent KTM's expansion into smaller displacement, more accessible street motorcycles, leveraging their engineering expertise.
Manufacturing Location:
Primarily Austria for earlier models, with later production potentially shifting to India through the Bajaj partnership for certain models.
