It's the Backup Fender ... catches all the mud that makes it past the Primary Fender. You can never have too many layers of fenders.
OK, OK, I completely agree that these adventure bike beaks are silly looking, with some downright ridiculous. I'm looking at you, Ducati Multistrada, with your two beaks ... oh, I guess it's that layered thing too: One is the Primary Beak, and the other is the Backup Beak. I'm not sure which is which, but hey you have two so you got
that goin' for ya.
I do think the Triumph Tiger's beak is probably the best looking ... the most tolerable ... I've seen. Wait, a Tiger ... with a beak? So weird.
To beak or not to beak? That is the question.
And what's going on here? Spy vs Spy? Heckle and Jeckle? (I realize it's not an Adventure Bike)
