Thanks for your feed back.
I travel in to London from Tunbridge Wells and it takes at least 1 hour 40 minutes each way door to door. Bike should knock off 30 - 40 minutes each way. Have spent 17 years sitting on a train and need a change.
Can only have one bike and main reason is to ride to work so need something that does it all. Really like the GS Adv and a friend has one and cannot speak highly enough of it for his commute.
Have a few options on parking other than bays which I will look in to.
Will have to put up with the salt, although these bikes must be better at dealing with every day use than the Jap bikes.
You wouldn't find me on a train if I could do the commute on the bike, even if it was a crappy old ER5 (believe me, I consider these to be just about the worst bike I've ever ridden) or constantly raining.
You will find that the corrosion issue isn't as bad as it was a couple of years ago. Most of the 1200 with faulty engine paint have been changed now. if you buy a bike that still has warranty remaining and you find any engine paint corrosion, just take it to your BW dealer for him to sort.
Set yourself up an easy access hose pipe and give the bike a quick blast off daily, to get the worst off whilst it's still wet.
The 1200 GS/ADV's do get very dirty 'it's the exposed back end you know' so you might want to fit a hugger. Be very careful which you choose, one or two are good. The rest aren't worth using. I gave up and just get dirty boots

I'm often on the bike for 6-8 hours a day.
Make sure 'as has been said already', you have good waterproofs for winter and ventilated protective clothing for summer. Don't let yourself get cold. There are quite a few options here including heated clothing and other stuff you can attach to the bike to help protect your hands and legs. Have a look around the forum, you'll be surprised what some guys put on their bikes to keep Mr frost at bay.
I like the BM because if I drop it I've only got to pick the thing up and get on your way. With the KTM you might have other issues to deal with. I can't help thinking the tank looks a bit vulnerable. But thats MHO.
