I think it's also worth pointing out that if it is indeed a test bike, it won't be in it's best Sunday suit.
Most automobile spy photos we see are of hubcapless, plastic-clad, four-wheeled dogs. In fact, sometimes if the manufacturer wants to test a sub-system, they'll just throw it into anything they see fit. The front wheel steering system snapped on an R1 a few years back is a good example. Who know's what Triumph is up to?
All in all, I'm just happy to see manufacturers trying out new models and different engine configurations which may end up filtering their way down to us lot. Getting them washed and dressed before the go on stage is the easy part.
