Introduced during a transformative era for KTM, these large-displacement single-cylinder motorcycles combined competition-proven Rotax-derived engine architecture with advanced chassis technology. The 625 SXC was designed as a hard-charging enduro machine with long-travel suspension, while the 660 SMC transformed the same fundamental platform into an aggressive supermoto with sticky road tires and powerful brakes. Both models featured KTM signature orange-framed trellis chassis with chromoly tubing, WP upside-down front forks, and a proven wet multiplate clutch system. These motorcycles became favorites among serious off-road enthusiasts and supermoto racers alike.\nSERVICE \u0026amp; REPAIR SCOPE:\n- Complete engine disassembly and rebuild procedures\n- Cylinder head valve service and camshaft inspection\n- Piston, cylinder and conrod bearing replacement\n- Clutch assembly overhaul and adjustment\n- Carburetor Keihin PWK jetting and tuning procedures\n- Fuel tap and fuel system maintenance\n- Cooling system flush, water pump inspection and thermostat testing\n- Transmission gear inspection, shift drum and fork replacement\n- Primary drive and starter clutch service\n- Frame inspection and swingarm bearing replacement\n- WP suspension overhaul, oil change and linkage service\n- Steering head bearing adjustment and replacement\n- Brake caliper rebuild, disc inspection and master cylinder service\n- Electrical system troubleshooting, CDI and ignition coil testing\n- Stator, regulator-rectifier and wiring harness inspection\n- Wheel bearing replacement and spoke tension adjustment\n- Exhaust system inspection and replacement\n- Complete torque specifications and maintenance schedules\nTECHNICAL SPECIFICATIONS:\n- Engine: Liquid-cooled, single-cylinder, 4-stroke, SOHC\n- Displacement: 625 cc (625 SXC) \/ 660 cc (660 SMC)\n- Bore x Stroke: approximately 100 x 80 mm\n- Compression ratio: varies by model year 9.5:1 to 11.3:1\n- Induction: Keihin PWK carburetor 41mm\n- Transmission: 5-speed or 6-speed constant mesh\n- Clutch: Wet multiplate, hydraulically actuated\n- Frame: Chrome-molybdenum steel trellis frame\n- Front Suspension: WP USD forks, 48mm\n- Rear Suspension: WP monoshock with linkage\n- Brakes: Front 300mm+ disc, Rear single disc\n- Dry Weight: approximately 125-135 kg depending on model\nDIAGNOSTIC INFORMATION:\n- Hard starting or no start diagnostics covering compression, spark and fuel delivery\n- Valve clearance symptoms and adjustment intervals\n- Overheating causes and cooling system pressure testing\n- Clutch slipping diagnosis and plate wear inspection\n- Gear jumping out of selected ratio and shift drum inspection\n- Excessive chain\/sprocket wear and final drive troubleshooting\n- Abnormal engine noise top-end and bottom-end diagnosis\n- WP suspension bott\u003c\/p\u003e\n\u003cp\u003eInstant download — no shipping, no waiting.
