MOOSE OFFROAD KTM-117-BU Blue OEM Fit Radiator Hose Kit — KTM / Husqvarna 450 & 500 EXC-F / FE

MOOSE OFFROAD — Samco® Sport UK Engineering, Precision OEM Fitment, and Triple-Layer Silicone Durability for KTM and Husqvarna 450/500cc 4-Strokes

Maintain your machine's factory cooling architecture while significantly upgrading its reliability with the MOOSE OFFROAD KTM-117-BU OEM Fit Radiator Hose Kit. Manufactured in the UK by Samco® Sport—the world’s most trusted name in performance silicone—this kit is designed specifically for big-bore KTM and Husqvarna four-stroke models. Unlike "Race Fit" kits that bypass the thermostat, the "OEM Fit" design mirrors your standard hose routing exactly, allowing you to retain the factory thermostat for optimal engine warm-up and temperature regulation on the trail or the street.

Constructed from premium European-grade silicone, these hoses feature three layers of reinforcement fabric for exceptional burst pressure resistance. This multi-layer design doesn't just handle high engine heat better than stock rubber; it provides far superior resistance to trail debris punctures and crash impacts. The vibrant blue finish is UV-stable and color-matched to factory Husqvarna standards, providing a professional factory look for Husky models or a striking custom accent for KTM machines. Every hose is hand-wrapped and 100% visually inspected in the UK to ensure absolute perfection.

• Exact OEM Design: Mirrors the fitment of standard factory hoses for a direct replacement that retains the factory thermostat.
• Samco® Sport UK Quality: Hand-wrapped and 100% visually inspected by the global leaders in silicone hose technology.
• Triple-Layer Reinforcement: Provides high burst pressure ratings and added protection against trail-side impacts and debris.
• Thermal Excellence: High-quality silicone rubber handles higher temperatures and more heat cycles than standard rubber.
• UV-Stable Blue Finish: High-quality pigments are guaranteed not to fade under extreme engine heat or direct sunlight.
• Precision Engineered: Specifically tuned for the plumbing of the 450cc and 500cc/501cc four-stroke engines.

Moto-House MX Pro Tip:

Big-bore dual-sports like the 500 EXC-F or FE501 can generate intense heat during slow-speed technical climbs or when idling in traffic. The MOOSE OFFROAD KTM-117-BU kit is a "reliability-first" upgrade that prevents the cracking and hardening common with stock rubber hoses. Because these silicone hoses are more robust than OEM rubber, we recommend using a dedicated stainless steel clamp kit designed for silicone to avoid damaging the material. When installing, ensuring a clean radiator port interface will provide a leak-free seal for the life of the bike.
