Usher's no window shopper, he's more of a hands-on guy when it comes to luxury motorbikes -- which explains why he got a SoHo dealership to open just for him.
Our sources at Ducati Triumph New York tell us ... the singer was there Monday to scope out Ducati's XDiavel model. The store's normally closed Mondays, but when a loyal superstar customer calls, doors open.
Ush took the gorgeous all-black 156-horsepower bike out for a spin, but we're told he's still not convinced he wants to drop $25k for it.
Wild guess? He'll be back ... we know he can afford it.
