Torque Characteristics: Designed for strong low-end and mid-range torque delivery suitable for snowmobiling conditions, with specific torque figures detailed in the manual. Fuel System Injection Type: Electronic Fuel Injection (EFI) is common for these 4-stroke models, ensuring precise fuel delivery and emissions control. Cooling System Cooling Method: Liquid-cooled, utilizing a radiator, coolant hoses, thermostat, and water pump. Lubrication Oil Type Specification: Requires specific synthetic 4-stroke snowmobile engine oil meeting Polaris' recommendations (e.g., proprietary blends or industry standards like API SJ or higher, SAE 0W-40 or 5W-40 depending on temperature). Consult manual for exact specifications. Engine Displacement Displacement: Varies by model; common displacements for Polaris 4-stroke engines in this era include 600cc, 700cc, and 750cc-class engines, often derived from Liberty or other Polaris-developed platforms. FST models typically feature turbocharged engines in the 750cc range. 🔧 Transmission Standard Transmission Type: Automatic Variable Transmission (CVT) using Polaris' P-85 Drive Clutch and an Automatic Tension Drive (ATD) Driven Clutch. Optional Gearing Options: N/A for standard CVT setups; manual will detail gear reduction ratios within the chaincase. Features Clutch Service: Detailed procedures for clutch inspection, cleaning, spring replacement, roller/weight service, and belt replacement, crucial for optimal performance and longevity. Chaincase Lubrication: Specification for chaincase lubricant (e.g., Polaris specific or SAE 80W-90 gear oil) and recommended service intervals. 📐 Dimensions Exterior General Layout: Snowmobile platform with a two-up (FS) or performance-oriented (FST) seating configuration, tunnel, skis, and track system. Weights Dry Weight: Dry weights for these models typically ranged from approximately 450-550 lbs (204-250 kg), depending on the specific configuration and features. Cargo Storage Capacity: Minimal integrated storage, often supplemented by optional racks or bags. Manual will detail any existing storage compartments. 🛡️ Safety Features Ratings Safety Standards: Adherence to industry safety standards for snowmobile operation, braking, and rider protection. Manual will detail any specific safety warnings or procedures.
