Moto-House MX Pro Tip:

The 2018-2021 CRF250R utilizes a high-output cooling loop to manage the heat of its dual-cam engine. The left-side radiator is essential for maintaining even thermal distribution across the cylinder. If your current radiator is twisted or has collapsed fins from a tip-over, your cooling efficiency is compromised. When replacing your radiator with the MOOSE OFFROAD 1901-0866, we recommend a complete cooling system flush and the use of high-performance racing coolant to keep your Honda running at peak horsepower.
