I put them on my 17 Road King and can't believe the difference they make. Not really a fan of the looks but the reduced wind in 50 degree and under is nice.
I installed the fangs but first I installed the Kury "dog bowl" or should I say triple tree air deflector. It made a good difference alone but the fangs really do the trick.
My ole Heritage had them so it wasn't anything new to me. Putem on and don't look back.
Harleyrib, Fangs is the slang word for lowers, fork lowers, fork wind deflectors, or fork lowers. Google those terms and it will show you several versions and styles. Harley, Kury, and several others sell them. also www.eglidegoodies.com
