Moto-House MX Pro Tip:

The 2017-2020 CRF450R engine relies on high-efficiency cooling to maintain consistent horsepower throughout a 30-minute moto. The right-side radiator is the "master" side for filling and system pressure regulation. If your current radiator is twisted or has collapsed fins—even if it isn't leaking yet—you are losing vital cooling efficiency and risking an engine-damaging boil-over. When replacing your radiator with the MOOSE OFFROAD 1901-0864, we recommend a complete system flush and the use of a high-performance racing coolant to ensure your engine stays in the power band.
