Part of the whole thing about the S3 is that it does one thing, and one thing well. It's not exactly adaptable - you can't just sling some luggage on it if you decide to go around Scotland for a bit. That might end up being slightly restrictive.
[*]Oddly, I wasn't much a fan of the digital speedo. In a world where you have to constantly have one eye on the dash to check your speed, I much prefer something analog than having to translate a number into something that answers the question 'how fast?'
Yes, yes you can.
I owned a '07 1050 for two years and had no trouble slapping some luggage on it for some touring/longer rides.
Not odd at all, I really don't like digital speedo's either...
To be fair I haven't kept up with the bike arena since I stopped riding about 10 years ago so I don't know how common the digital speedo's are.
