KTM 390 Duke RC390 Silicone Coolant Radiator Hose Pipe Kit
Upgrade your KTM 390 Duke RC390 with the SPEED&COOL Silicone Radiator Hose Kit. Crafted from high-quality reinforced silicone, this kit replaces stock hoses with a durable, heat-resistant, UV-stable set designed to withstand the demanding conditions of high-performance riding. The orange color adds a bold aftermarket look while signaling enhanced performance and reliability.
Engineered as a 3-ply hose with a 4.5mm wall thickness and polyester reinforcement, these hoses resist collapse under high coolant pressure and stay flexible across a wide temperature range. They are tested to endure temperatures from -60°C to 260°C and operate safely at 0.3–0.9 MPa, with a bursting pressure of 2 MPa. UV, water, ozone, and oxygen resistance help them last longer in sunny rides and harsh environments.
Designed for KTM 390 LC4 Duke RC390 models from 2013 to 2019, this kit is a direct upgrade to the radiator coolant system, improving flow stability and reducing the risk of leaks due to aged or degraded hoses. Each set is orange, making it easy to visually confirm correct installation and a clean, consistent engine bay look.
