I did the same as you...just popped in for a look (happened to have my licence with me as I had just tested a Multistrada). The sales guy insisted I take it for at least a couple of hours. I wasn't sure to start with (mainly as I am a short arse)...but after 2hrs on my way back to the showroom...I did consider just riding past and keep on going for another 2hrs.
A week later, I was back for another 2hr ride....and then ordered the Thunder Grey TE too. I should have mine next week...hopefully just in time for our trip to Wales as it will perfect for running it in and getting to know the bike.
I toyed with the idea of replacing the can for an Akro...but couldnt justify the expense without hearing it first

.
I'm also not planning on spending 616 on the Nav 4....might see if they are cheaper next year
