Ethylene glycol-based antifreeze (typically 50/50 mix with distilled water). Specific Polaris coolant part number may be listed.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid.
Common Wear Items:
Drive belts (clutch wear), suspension bushings, wheel bearings, and carburation (fouling or adjustment issues due to fuel quality or age).
Electrical Components:
While generally reliable, starter motors, ignitions coils, and battery connections can be points of inspection.
2 Stroke Care:
Proper fuel-to-oil ratio (if premixing, though this model likely has oil injection) and using high-quality 2-stroke oil are crucial for engine longevity.
Polaris Atv Legacy:
Polaris has a long-standing history in the ATV market, known for innovation and performance-oriented recreational vehicles.
