XL40 LED Headlight Kit w/ Yamaha Shell - Yamaha YZ250FX/450FX ('21-23)

The Baja Designs XL40 Yamaha YZ250FX/450FX Headlight Kit with Shell is a moto-specific LED headlight assembly built for trail riders, Dual Sport enthusiasts, and desert racers who refuse to let darkness cut a ride short. Inspired by the performance lineage of the XL80, the XL40 brings serious illumination to a broader range of dirt bikes without overwhelming the lower-output OEM stators common on off-road motorcycles.

At the heart of this kit is the XL Trail Lens, which produces both a vertical and horizontal beam pattern engineered for tight singletrack and technical terrain. Rather than throwing a harsh hotspot down the center of the trail, the Trail Lens redistributes light across the near field and periphery — exactly what you need when navigating quick elevation changes, blind corners, and rooted terrain at speed.

Installation is straightforward because the XL40 arrives pre-mounted inside a vehicle-specific headlight shell, with a complete wiring harness and all necessary hardware included. There's no fabrication, no guesswork — it drops into place and connects cleanly to your existing setup. For YZ250FX and YZ450FX riders who want dependable, well-engineered trail lighting without a complicated install, this kit covers every base.
