JAVIK Radiator for Polaris Sportsman Series
This radiator is designed as an OEM replica for several Polaris ATV models, including 2004–2020 Sportsman 400/450/500 cycles and Haw-keye 325 variants. It targets riders seeking a direct-fit replacement that mirrors factory dimensions and mounting points. Best for long-term durability in regular riding and mild to moderate trail conditions. The description emphasizes abrasion and corrosion resistance, supporting extended service life in adverse environments.
Who it’s best for: ATV owners needing a faithful OEM-style radiator for Polaris Sportsman models with multiple year ranges. This option is also suitable for riders who want straightforward installation without fabricating mounting hardware. A minor limitation is that exact fit can vary by sub-model; verify the exact part number compatibility before purchase.
Radiator For Polaris Sportsman 450/570 Pro XD Mid-Size
This radiator is built to fit 2021–2026 Polaris mid-size platforms, including Sportsman 450 HO and 570 models, plus Ranger 570 and Pro XD Mid-Size variants. It ships with a high-performance aluminum core and lower-mount bushings, which aid installation and stability. Best for modern mid-size setup where upgrade to a more robust cooling solution is desired. Caution: exclude older or non-listed sub-models to avoid fitment issues.
Who it’s best for: Owners of 2021–2026 Polaris 450 HO, 570 and related mid-size vehicles seeking improved cooling with included mounting hardware. Choose this if you want a ready-to-install option with focused compatibility for newer frame designs.
NICHE Radiator for Yamaha Kodiak 450
This NICHE radiator is specified for Yamaha Kodiak 450, featuring a single-row core with a cap included. It aligns with OEM part number BB5-E2461-00-00, offering a compact cooling solution suitable for smaller riders and lighter-duty trail work. Best for Kodiak 450 owners who want a straightforward, no-fruss upgrade with a cap included for a tight seal. Limitation: single-row design may be less efficient than multi-row options in extreme heat or heavy-load conditions.
Who it’s best for: Yamaha Kodiak 450 riders seeking an economical, ready-to-install radiator with a cap. Choose this when space and weight savings are priorities, and if the primary concern is maintaining stock clearance rather than peak cooling capacity.
1241477 1240520 1240305 1240152 Upgraded ATV Radiator
This EZAPEX-branded unit covers a broad slate of Polaris models, including 400/450/500/570 series and Hawkeye 325, spanning years from 2004 through 2021 for many configurations. It emphasizes durable aluminum construction with corrosion resistance and enhanced cooling efficiency versus some OEM units. Best for riders needing a versatile replacement across multiple Polaris generations without purchasing separate model-specific radiators. Caution: verify the exact OE numbers (1240152, 1241477, 1240520, 1240305) to ensure a perfect match for your bike’s chassis.
Who it’s best for: Polaris ATV owners who want a single radiator option that crosses several model lines and year ranges. Opt for this if you value a broad compatibility footprint and solid aluminum performance in one part. Avoid this if your ATV’s exact sub-model requires a more precise fit that only a narrow model-specific radiator can guarantee.
NICHE Radiator for Polaris Sportsman SP X2 570
This NICHE radiator targets Polaris Sportsman SP X2 570, Touring 570, and related variants with OEM part numbers 1241477, 1240520, 1240305, and 1240152 in mind. It emphasizes compatibility with SP/X2 570 and 570 Touring, offering a reliable core height and width that align with these models. Best for riders who own SP/X2 or Touring specifications and seek a direct replacement that preserves stock-fitment and cooling performance. Limitation: may not fit non-SP/X2 editions where bodywork or mounting points differ significantly.
Buying Guide
- What to check before buying: Confirm exact OEM part numbers and model compatibility listed by the seller. Look for radiators with aluminum cores for better heat transfer and corrosion resistance.
- Material and construction: Aluminum cores are common for performance and durability. Avoid proton-coated or inconsistent cores if you plan heavy-duty use.
- Fitment nuance: Some radiators list broad compatibility; always verify specific year and sub-model compatibility with your ATV’s VIN or parts fiches.
- Installation considerations: Some sets include only the radiator and hoses, others come with mounting bushings or brackets. Choose a kit that matches your current mounting setup to minimize fabrication.
- Performance expectations: Higher fin density and multi-core designs generally improve cooling but may add weight or price. Balance cooling needs with your riding conditions and weight considerations.
