Displacement: Approximately 597cc (common for Yamaha's 600cc series). Performance Horsepower Range: Typically in the 90-115 HP range, depending on the specific model (e.g., SRX models often higher output). Torque Output: Specific torque figures not provided, but expected to be robust for a 600cc 2-stroke. Fuel System Carburetion: Likely dual Mikuni VM or BD series carburetors (e.g., VM34, VM38). Fuel Type: Unleaded gasoline, often requiring a specific octane rating (e.g., 87 or 89 octane). Cooling System Cooling Method: Liquid-cooled. Lubrication System Oil Delivery: Yamaha Oil Injection (YSOI) system or pre-mix depending on specific model variant. 🔧 Transmission Standard Clutch System: CVT (Continuously Variable Transmission) featuring Yamaha's distinctive clutch design (e.g., Primary Drive Clutch and Secondary Driven Clutch). Features Gear Reduction: Integrated into the clutch system and chaincase for optimal power transfer. 📐 Dimensions Exterior Track Dimensions: Varies by model, but common track lengths for this era were 121" or 136" with widths of 15" or 20". Weights Dry Weight: Generally in the range of 450-550 lbs (204-250 kg) depending on the specific model and features. 🛡️ Safety Features Active Features Braking System: Hydraulic disc brake system with a handlebar-mounted lever.
