MOOSE OFFROAD YAM-72-BL Blue Race Fit Radiator Hose Kit — Yamaha YZ250FX (2015-2019)

MOOSE OFFROAD — Samco® Sport UK Engineering, Race-Bike Flow Design, and Maximum Cooling Performance for the Yamaha YZ250FX

Optimize your Yamaha’s cooling capacity for the most demanding trails with the MOOSE OFFROAD YAM-72-BL Race Fit Radiator Hose Kit. Specifically engineered for the 2015-2019 YZ250FX, this kit is designed to handle the intense heat generated during technical cross-country racing. Manufactured in the UK by Samco® Sport—the world leader in silicone hose technology—these hoses are a critical upgrade over standard rubber, which can soften and expand under the high-pressure conditions of off-road competition.

The "Race Fit" design streamlines the cooling path to promote faster coolant circulation and improved radiator efficiency, keeping your engine at peak performance even in tight, low-airflow sections. Each hose is hand-wrapped with three layers of premium European-grade reinforcement fabric, providing exceptional burst pressure resistance and shielding against trail debris or crash damage. Utilizing Zero Block tooling technology, the internal junctions are clear and free of restrictive flashing, ensuring maximum flow. The vibrant blue finish is UV-stable, ensuring your bike maintains its factory-racing look without fading under extreme heat or sun exposure.

• Race Bike Design: Streamlines the cooling system for more efficient flow and stable engine temperatures in off-road environments.
• Samco® Sport UK Quality: Hand-wrapped and 100% visually inspected by the global leaders in silicone technology.
• Triple-Layer Reinforcement: Advanced fabric layering offers elite-level burst pressure and superior crash resistance.
• Zero Block Technology: Guarantees smooth internal flow paths by eliminating dangerous manufacturing flashing.
• High-Temp Resilience: European-grade silicone is guaranteed to withstand thermal loads up to 356°F.
• UV-Stable Blue Finish: Vibrant racing blue pigments won't fade or crack over time, matching Yamaha factory aesthetics.

Moto-House MX Pro Tip:

The YZ250FX is a cross-country weapon, but slow-speed technical riding can quickly lead to overheating. The MOOSE OFFROAD YAM-72-BL kit is an essential reliability mod to ensure your cooling system remains pressurized and leak-free. Because these silicone hoses are much tougher than stock rubber, we recommend using a dedicated stainless steel silicone-specific clamp kit to ensure a leak-free seal without damaging the hose. For riders tackling extreme terrain, we also suggest pairing this kit with a high-performance coolant to further stabilize engine temperatures.
