Binding Type:
N/A (Digital PDF)
Paper Type:
N/A (Digital PDF, user prints on desired paper)
Engine Type:
2-stroke, single-cylinder
Displacement:
Approximately 373cc (often referred to as 380cc for marketing purposes)
Bore X Stroke:
Specifications typically found within the manual, essential for rebuilds.
Cooling System:
Liquid-cooled
Horsepower:
Generally in the range of 45-55 hp, depending on tuning and specific year variations. Exact figures would be in the manual.
Torque:
Strong mid-range and top-end torque characteristic of larger displacement 2-strokes. Specific figures available in the manual.
Carburetor:
Typically a large-bore Keihin carburetor (e.g., PWK 38)
Fuel Type:
Unleaded gasoline, typically requiring a higher octane rating and 2-stroke oil pre-mix.
Ignition System:
Digital CDI ignition (capacitive discharge ignition)
Safety Certification:
Off-road motorcycles are generally not subject to the same crash test ratings as passenger vehicles. Focus on rider safety through design and maintenance.
Braking System:
Powerful hydraulic disc brakes front and rear, essential for control.
Suspension Control:
Adjustable suspension allows tuning for rider weight and terrain, enhancing stability and control.
Frame Construction:
Strong, rigid frame designed to withstand off-road abuse.
Handguards:
Often fitted as standard or common aftermarket additions to protect hands and levers.
Infotainment System:
Basic by modern standards. Typically consists of odometer, trip meter, and indicator lights.
Off Road Features:
Focus is on mechanical systems for off-road capability: powerful brakes, adjustable suspension, robust chassis, and strong engine output. No electronic rider aids found on modern bikes.
Connectivity Features:
None. This is a pure off-road motorcycle from the late 90s/early 2000s.
Oil Change Interval:
Frequent, typically every 5-10 riding hours for the gearbox oil, depending on usage. Engine oil (pre-mix) is part of fuel.
Air Filter Cleaning:
Regularly, often every few riding hours or after dusty conditions.
Spark Plug Inspection:
Periodically, as per manual recommendations, to ensure optimal combustion.
Gearbox Oil:
Specific KTM-recommended gearbox oil (e.g., SAE 10W/40, API GL-4). Manual will specify exact type and viscosity.
Coolant Type:
Ethylene glycol-based antifreeze/coolant mixture. Manual will specify ratio and type.
Brake Fluid:
DOT 4 brake fluid, as specified by the manufacturer.
Common Wear Items:
Piston rings, clutch plates, wheel bearings, steering head bearings, fork seals, exhaust packing.
Engine Performance:
While powerful, maintaining the 2-stroke engine's tune and proper lubrication is critical to prevent premature wear or damage. Carburetor jetting can be sensitive to altitude and temperature.
Maintenance Schedule Emphasis
Importance:
Strict adherence to the periodic maintenance chart in the service manual is crucial for maximizing the lifespan and reliability of the KTM 380 EXC.
Brand Focus:
KTM has a long-standing reputation for producing high-performance, race-bred off-road motorcycles, particularly in motocross and enduro disciplines.
Platform:
The 380 EXC was part of the evolution of KTM's LC4 engine platform, adapted for enduro competition. It represented a significant displacement for a 2-stroke enduro at the time.
Model Naming:
The 'EXC' designation signifies the Enduro Competition series, emphasizing off-road performance and capabilities.
Manufacturing Location:
Primarily Austria, KTM's historical manufacturing base.
