Show original supplier description
The Yamaha Radiator Fan Kit, part number B3J-E24E0-V0-00, is engineered to augment the cooling performance of specific Yamaha off-road motorcycles. This kit installs a dedicated cooling fan onto the right-side radiator, directly boosting the machine's overall heat dissipation capabilities. Designed with performance in mind, this fan kit is particularly beneficial for riders who frequently encounter tight, muddy terrain or participate in competitive events where engine temperature management is critical. The installation process is streamlined for ease, utilizing the motorcycle's existing pre-wiring for a plug-and-play connection that requires no permanent modifications to the vehicle. Compatibility is specific to several Yamaha models: the YZ250FX from 2020-2024, the YZ450FX from 2019-2023, the WR250F from 2020-2024, and the WR450F from 2019-2023. A specific note for 2019 YZ450FX owners indicates that the ECU may require programming to properly control the fan's operation; owners should consult their dealer to confirm this has been enabled.
