Proton Factory Double Radiator – Rieju MRT / HM / VENT / Beta

Running an extreme build and cooling is a critical concern? The Proton Factory double radiator delivers +30% cooling capacity compared to a standard double radiator, thanks to an optimised vertical position and laser-cut mounting brackets.

Compatibility:

• Rieju MRT, HM, VENT, direct fit (note: the frame bracket must be re-drilled to 12 mm)
• Beta, also compatible

Benefits:

• 🌡️ +30% cooling compared to a standard double radiator
• 📐 Maximum vertical position to further improve airflow and thermal efficiency
• 🔧 Laser-cut brackets for precise fitment on Rieju, HM, VENT and Beta frames
• 🏁 Built for extreme builds, enduro, pit bike racing and high-performance setups

Note: on Rieju models, the frame mounting bracket must be re-drilled to 12 mm. Installation also requires reducing the steering stops.
