Since I recently wrote about carbon fiber motorcycle parts for a lighter overall weight or simply for racing/high tech looks, here a good address for a smooth 5-3/4″ long and 6″ diameter standard headlight (my preferred size on any bike) in natural carbon fiber with black metal clamp ring/bracket (you can opt for polished or chrome ring).
It comes from Headwinds, a leader in custom motorcycle headlights since 1992. Lamps, and many sizes and shapes of mounting block with bolts are sold separately. Made In the USA. $211.95. Contact Joel Felty on my behalf at 626-359-8044 (California) or visit Headwinds
