USTPO Universal Dirt Bike Oil Cooler (Red)

The USTPO universal oil cooler is designed to fit a wide range of 50cc to 140cc dirt bikes and pit bikes with horizontal engines. It emphasizes effective cooling by transferring heat from engine oil to the cooler fins, helping maintain stable oil temperatures during aggressive riding and long climbs. The cooler is constructed from premium aluminum alloy to balance light weight with strong thermal conductivity, reducing the risk of heat soak during extended sessions. Its compatibility with brands like Loncin, Zongshen, Lifan, Shineray, and Yinxiang makes it a versatile upgrade for many Chinese-made pit bikes and ATVs.
Important considerations: ensure that mounting dimensions align with your bike’s frame and existing oil lines. The universal design offers flexibility, but proper routing of hoses and mounting brackets is essential to prevent interference with crankcase components or exhaust heat. Regular inspection for leaks and corrosion is recommended in dusty, off-road environments. This model is sold in several color variants, and the red version is commonly preferred for visibility and aftermarket styling, though performance is similar across colors.
ABCERRSI Blue Motorcycle Oil Cooler Kit

The ABCERRSI kit is built for 50cc to 140cc horizontal engines, including popular pit bike platforms like Kayo, Apollo, Bosuer, Xmotos, and similar Chinese models. The kit’s aluminum construction provides a balance of durability and heat transfer efficiency, while the multi-layer cooling design helps dissipate heat quickly under strenuous riding conditions. Installation specs emphasize compatibility with a 90mm center-to-center mounting spacing and M10 mounting holes, making it a practical choice for riders who want a straightforward bolt-on upgrade without extensive fabrication.
Key considerations: confirm exact fitment against your bike’s frame and oil cooler mounting points. Aluminum’s lightweight profile is advantageous for performance-sensitive builds, but ensure adequate clearance from exhaust components and coolant lines. For riders who value a stylish blue finish in addition to performance, this option pairs well with a variety of bodywork and plastics while still providing solid cooling results.
USTPO Red Universal Dirt Bike Oil Cooler

This second USTPO model emphasizes the same universal compatibility across multiple brands and engine sizes, with a red finish for those who prefer a more aggressive look on their dirt bike. Aluminum construction provides dependable thermal conductivity and resistance to corrosion in off-road environments. This design reinforces oil cooling during high-rev sessions and in hot, dusty conditions—common on popular American dirt biking trails and desert rides.
Practical notes: verify hose diameter compatibility with your current oil lines to avoid leaks. Properly seating the cooler and securing mounting points is important for vibration resistance on rough terrain. While aesthetics vary, the core cooling performance remains a central benefit of this option.
Estink 5 Row Aluminum Oil Cooler Kit

The Estink 5 Row Aluminum Oil Cooler is designed to deliver high cooling capacity in a compact footprint, making it suitable for a broad range of dirt bikes, ATVs, and pits bikes. Its aluminum alloy construction offers robust heat dissipation while staying relatively lightweight, a key factor for performance-focused riders who want more aggressive oil cooling without adding significant weight to the bike. The kit is advertised as compatible with many 50cc–140cc horizontal engines from various Chinese manufacturers, including Kayo, Apollo, and Xmotos, which are common in American markets.
Key considerations: a five-row design provides more surface area, which can translate to improved cooling at the cost of slightly increased front-end intrusion. Ensure adequate space behind the radiator to route hoses and avoid interference with the bike’s frame, footpegs, or exhaust. As with all aftermarket oil coolers, proper installation and leak testing are essential to long-term reliability in off-road use.
Refit Pit Dirt Bike Oil Cooler Kit

The Refit Pit dirt bike oil cooler is designed for 70cc–140cc engines including Loncin, Zongshen, Lifan, Shineray, and Yinxiang horizontals. The kit emphasizes quick engine oil cooling, which can reduce engine wear and improve radiation of heat from the crankcase under high-load conditions. It’s marketed as suitable for Go Karts and other small displacement machines, making it a flexible upgrade for riders who swap engines or ride a mix of dirt bikes and ATVs. Aluminum construction supports durability and corrosion resistance in off-road environments.
Important considerations: ensure components match your exact engine size and mounting points. Confirm hose routing clearances to avoid contact with the chain, exhaust, or foot controls. Regular checks for oil leaks and hose integrity will help maintain performance in challenging trail conditions.
ABCERRSI 4-Row GY6 Oil Cooler Kit

This 4-row oil cooler from ABCERRSI is positioned for GY6-based engines and other similar dirt pit bikes, offering a higher heat dissipation capacity in a compact package. The kit uses high-quality T-6061 aluminum to resist corrosion and maintain structural integrity under vibration. Fin spacing and overall design are aimed at maximizing heat transfer, which helps keep engine temperatures within the optimal range during long rides or aggressive throttle input. It also supports reliable operation in hot, dusty environments typical of off-road trails.
Considerations: verify that your bike’s frame allows a 4-row cooler, including clearance for hoses and mounting hardware. Proper torque on fittings and secure mounting are essential to prevent vibration-induced failures on rough terrain. This option is particularly suitable for riders who push their engines harder and want a robust cooling solution that remains efficient in demanding riding conditions.
Buying Guide: Key Purchase Considerations For Dirt Bike Oil Coolers
- Compatibility and fitment: Check engine displacement, mounting spacing, hose diameters, and frame clearance. Universal kits are flexible, but exact fitment reduces installation time and risk of interference.
- Material and construction: Aluminum is the standard for light weight and good thermal conductivity; ensure corrosion resistance for prolonged off-road exposure. Multi-row designs increase cooling surface but may require more space.
- Cooling performance: Consider climate and riding style. Aggressive riding in hot conditions benefits from higher cooling capacity, but ensure the kit won’t overly impede airflow to other critical components.
- Installation and durability: Look for kits with robust mounting hardware and clear installation instructions. Off-road vibration can loosen fittings; secure brackets and use thread sealant or locking compounds as recommended.
- Maintenance: Regularly inspect for leaks and hose wear. Clean fins to maintain airflow, and replace damaged clamps or lines promptly to prevent coolant loss.
- Aesthetics and integration: Color and finish can complement your bike’s look, but prioritize performance and fit first to ensure long-term reliability on trails and tracks.
- Cost versus benefit: A higher-priced cooler may offer better materials and cooling efficiency, but ensure the model aligns with your bike’s requirements and riding conditions.
