Engine Type:
V-Twin, 8-valve, DOHC, liquid-cooled
Displacement:
999 cc (cubic centimeters)
Bore X Stroke:
98 mm x 66 mm (approximate, to be confirmed in manual)
Compression Ratio:
12.5:1 (typical for this generation LC8)
Valve Train:
DOHC, chain-driven camshafts
Horsepower:
Approx. 115 HP (at crankshaft, to be confirmed in manual)
Torque:
Approx. 95 Nm (at crankshaft, to be confirmed in manual)
Fuel Delivery:
Electronic Fuel Injection (EFI) with twin throttle bodies
Fuel Type:
Unleaded gasoline, minimum 95 RON (Octane rating may vary based on region and specific tuning).
Fuel Tank Capacity:
Approx. 15 liters (to be confirmed in manual)
Oil Change:
Typically every 5,000 - 7,500 km or 6-12 months (refer to manual for precise intervals and oil type).
Valve Clearance Check:
Every 10,000 - 15,000 km (refer to manual for exact interval and procedure).
Chain Maintenance:
Regular cleaning, lubrication, and tension adjustment (frequency depends on riding conditions).
Engine Oil:
KTM recommends specific viscosity grades (e.g., 10W-50 or 15W-50) and JASO MA certified motorcycle oil. Specific brand recommendations or equivalents will be in the manual.
Coolant:
Ethylene glycol-based antifreeze mixture (e.g., Motorex Coolant M3.0 or equivalent). Refer to manual for correct ratio and type.
Brake Fluid:
DOT 4 or DOT 5.1 brake fluid (refer to manual for specific recommendation and bleeding procedure).
Clutch Fluid:
DOT 4 brake fluid (typically shares reservoir with front brake, refer to manual).
Common Wear Items:
Clutch slave cylinder seal, fuel pump, voltage regulator/rectifier, wheel bearings, rear shock absorber linkage bearings.
Engine Characteristics:
LC8 engines can be sensitive to lean fueling at lower RPMs; proper maintenance and potential ECU tuning can mitigate this. Vibration can be a characteristic due to the V-twin configuration.
Maintenance Schedule Detail:
The manual will provide detailed torque specifications, component wear limits, and step-by-step procedures for all scheduled maintenance tasks.
