I rode a 1200 LC over 4,500km in three weeks in South Africa in 2014. I bought an 1150 in September 2015 and I've put about 4,000km on it since then (including riding it home from Germany).
The LC is a fantastic bike. It's definitely more refined than the 1150. I really enjoyed playing with the "toys" on the LC. Putting it into dynamic mode and throwing the bike around on twisty tarmac, then later putting it into enduro mode and taking it on to rough, rocky gravel roads. The different modes make it feel like a completely different bike. It's not just a gimmick. The whole bike gets soft and bouncy when the suspension is put into enduro mode, and it's rock hard in road mode. The engine tone completely changes when changing engine modes. It sounds growly and sputtery in enduro mode, and it's smooth and refined in road mode.
I loved the LC so much, it almost seduced me. I seriously considered buying one. However, I'm the kind of guy that buys a bike with his heart, rather than his head. I don't care what the specifications say. I don't care if the 1150 is so many kilos heavier than the 1200, or it's got so much less power. The 1150 just attracted me. I did my research, so it was an educated choice. I know what the common faults are etc on the bike, so I know what I may need to deal with in the future. The first time I rode an 1150 was when I was test-riding my own before I bought it. Coming from a V-twin Honda Deauville that ticks over like a mouse's heart, the 1150 felt like riding a diesel generator. There were no fancy read-outs or buttons to change modes, but it made me grin. I loved it immediately. On the 1700km ride home, as I learnt its ways, I loved it more.
If you're the type of person that buys a bike on PCP, changes it every three years, likes to have the very latest technology, and just want a smooth, comfortable bike to get you around, the LC would be a perfect choice.
If, however, you're like me and like to have a bike you can bond with - a bike with character, if you like to work on your bike, dismantle it, rebuild it, get to know it and keep it for a long time, I think you'll fall for an 1100/1150.
