Hi Sam, I have a M1000sie - and she does just the job for me.
Make sure you check the engine casings, as some of thses engines (in the MS too) were prone to paint flaking off. Not a big prob, but something to factor in when haggling on price - as most have been done under warranty.
Otherwise, not much 'individual probs' - just make sure you check all the usual bike type things, and that it does have complete service history.
Any monster over 2 years old will have had its first full 2 year belt service, where shims etc get checked too.
I can get about 125ish miles to the tank
before the fuel light comes on, if bimbling, but if going a tad sharpish
it can be down to 80/85
