I thought that when I got my 1150 - after all its just a stepping stone to the 1200 isn't it?
18 months on and "no it isn't any more". Plenty of people here have had both and rate the 1150 as the the better bike. I understand your money saving attitude, but don't hobble the bike for a few extra quid or you may not see the brilliant bike that it is.
Yup I'm on my third
I've got away and dabbled with speed (K1300GT) too fast, as in you needed to do 120mph to feel like you were moving at all, plus it was £9000 worth of bike even second hand that needed BMW service to keep the warranty etc and like the 1200 was Canbus so nothing was a DIY repair (Kerching!

)
My first 1150 (the one in my Avatar) was £2000 and had done 75,000 I loved it and with Hepco engine bars and the panniers I had fabricated for £50 each I was not fussed if I dropped it....
In fact when a mate asked to ride it and dropped it miss-reading the camber of the road I was more interested in capturing his embarrassment than picking it up!
Then I brought another with only 3000 miles, but I wish I'd kept the 75k one as it felt nice and loose, just worn in like old slippers!

I got knocked off that in a VERY minor spill, but it gave me the chance to get a big payout and buy a much newer bike (that's where the K1300 came in) just one 'proper' trip and it was going (see pics on my sig link) just never had the character of the 1150. Tried a 1200 but nope not for me, so traded in on this site for an 1150 with 22k and a wedge of cash
It's now loud with the Wunderlich cat eliminator, I've got a set of engine bars and Verns panniers and a Touratech top box (it's 2 seconds to remove) HID has let me see in the dark and my seat is off to Tony Archer this week to be made into a sofa...
All this done and still with enough cash to have a good 2/3 week trip to Europe later this year.
If I ever sell for another bike, I can unbolt everything and sell it separately as it all adds nothing to the resale in real terms.
