My vote would be for the blue, colour coding the black plastic behind the seat , under the grab rails & possibly the side panels might look nice. There's one like it in Red Bull graphics in Goggle Images that looks good.
Also a Red Bull version for sale on bikesales.com.au the other day don't know if it's still there.
There's always a lot of pleasure in making a bike 'Your Own'
Please make sure you post some pic's when it's all done.

Cheers.
