XL40 Yamaha YZ250FX/450FX (21-On) w/Headlight Shell Baja Desigins

The Baja Designs XL40 (D/C) LED Headlight Kit with shell for Yamaha YZ250FX/450FX motorcycle models is an all-new, moto-specific LED headlight that delivers outstanding performance for trail riders, Dual Sport enthusiasts, and desert riders who need reliable visibility when daylight turns to night. Inspired by the performance of the XL80, the XL40 carries forward the same trail-proven pedigree, delivering 5,224 lumens of usable illumination to a wider range of motorcycles.

Engineered specifically for dirt bikes equipped with lower-output OEM stators, the XL40 draws just 43.5W-making it a powerful lighting upgrade without the large power draw. Paired with our signature XL Trail Lens, the XL40 produces both a vertical and horizontal beam pattern with exceptional near-field and peripheral visibility.

Designed for tight, technical singletrack, the Trail Lens redistributes center beam intensity to eliminate harsh hot spots, improving clarity through vertical transitions, quick elevation changes, and tight corners. The result is a smooth, evenly distributed field of light that inspires confidence in the most demanding terrain.

The XL40 LED Headlight comes pre-installed within a new Yamaha '19-24 headlight shell, making this a plug-and-play kit for ease of installation.
