Check out the Yamaha site below with a number of paper models of their bikes that you can download, print and build.
I've downloaded a couple and will see how I go.
I've started with an R1 and it's not easy - I've nearly completed the front fairing - even this has taken about an hour and a half!
Check out the photo of a finished one - not sure if mine will look that good.
Give it a bash if you've got some spare time...
