Hello from Oxfordshire. I bought a K1200S new in 2008. In 2012 I added a sidecar for touring. It is heavily modified with hub-centre steering, car-type wheels with low profile tyres, upgraded brakes and an extra fuel tank. When I figure out how to post pics, I'll add some!
The bike has only done about 50 000 miles but is on its second gearbox (from a K1300).
I've ridden it from Spain to Ireland and from Slovenia to Latvia and Norway.
Can't fault the motor - shame about the gearbox!
