Specific displacement varies by YFM400 sub-model (e.g., 401cc for some Kodiak 400 models). Engine Displacement: Typically around 401cc (e.g., 392cc or 401cc depending on exact model year and variant of YFM400 Kodiak). Performance Bore X Stroke: Specifics vary by model year and variant, but for a typical 400cc class engine, might be in the range of 85mm x 70mm. Compression Ratio: Likely in the range of 8.0:1 to 10.5:1 depending on the specific engine tuning and model year. Fuel System Fuel Delivery: Carbureted (e.g., Mikuni) or Fuel Injection (EFI) depending on the model year and variant. The manual will cover specific systems. Fuel Type: Unleaded gasoline Lubrication Oil Type: Yamaha recommends specific Yamalube oils or equivalent API SG or higher, SAE 10W-30 or 20W-40 based on ambient temperature. Manual will specify exact grades and capacities. Cooling Cooling System: Liquid-cooled (radiator and fan) Coolant Type: Ethylene glycol-based antifreeze coolant mixed with distilled water at a 50/50 ratio. Manual will specify exact type and capacity. 🔧 Transmission Standard Transmission Type: Automatic Transmission with a Continuously Variable Transmission (CVT) system, often referred to as Ultramatic by Yamaha. May include a high/low range and reverse. Optional Optional Transmission: Not typically offered for this model; CVT is standard. Features Drive System: Selectable 4x4 (4WD) or 2WD, often with a locking front differential for enhanced traction. Transmission Fluid: Yamaha recommends specific Yamalube transmission oil or equivalent. Manual will specify type, viscosity, and capacity. Likely a specialized CVT fluid. 📐 Dimensions Exterior Length: Varies by model year, but typically around 77-80 inches (1950-2030 mm). Width: Varies by model year, but typically around 45-48 inches (1140-1220 mm). Height: Varies by model year, but typically around 45-48 inches (1140-1220 mm). Weights Dry Weight: Varies by model year, but typically around 500-550 lbs (227-250 kg). Ground Clearance: Typically around 8-10 inches (200-250 mm). 🛡️ Safety Features Ratings Safety Ratings: ATVs are not typically subject to standardized crash testing like passenger vehicles.
