For anyone curious what the De Nigro Racing tail tidy looks like with a US plate and stock US blinkers. Installed this weekend. Wound up cutting some of the license plate bracket off to better fit the US plate, some of the other larger bracket still shows underneath the plate, but still looks ok, and with the IXIL slip on, no need to worry about blinkers getting toasted. Quality seems decent, some of the mounting holes were a little awkwardly placed and tough to get a socket in.
Next step I might take is getting rid of the ugly US spec blinkers and replacing them with some minimal ones like from motogadget.
