Not sure if you have bought one yet (10th October - "thinking", 13th "want to try another screen"; perhaps you move fast!) but some comments after 4 years with a 1300GT - bloody fast, gear change smooths with age, always have an extended warranty (I'm not ahead in £ but I have peace of mind when you see the costs of some bits and I cannot justify any new bike at £15K+).
Mine came with a Z-Technic V-Stream (standard not the tall version) screen which was OK but at 6' 6" not tall enough for me. I now have a tall factory screen with a Laminar Lip - works better although my shoulders now get the breeze a bit. Overall I will keep this set up.
Superb tourer (all the RT/1600GT toys - ESA, Cruise, heated seats & grips, full luggage (topbox was an extra except on the runout EE model - then Xenon headlamp too) that out-drags a 1600GT (the victim argued he was faster if he dropped a gear - I said I would be too!). Not sure if Guernsey is the place for one but I assume you will take it across the water to Europe where it will shine. Mine has had 1x switchgear, a rear wheel bearing (at 10K but I think a one-off) and a oil tank fitting in the 12K miles I've had it, now 18K. Recalls include the hot-start loom fix and rear wheel carrier; early ones get a cam guide recall too. Paint on the FD is just flaking slightly - well documented on many models but the rest is mint at 9 years old (admittedly it is a summer bike).
I'm keeping it a while yet - just did the 18K service (ouch!) so now ready for more intergalactic riding when the weather improves. I get c.5-6K from a rear tyre a bit more from the front (PR4GTs) but would say I'm Captain Slow. You must use the GT heavy duty version; looking at Pirelli Angel A next.
