Smudger - looks like you know 1100's as your profile says you have an RT. But just in case this thread covers the issues I've had, and also those that seem to be fairly common.

Top front brake hose is a must. £33 from BMW. Mine went when I was close to home but was braking from speed going towards a roundabout. It could have ended very badly if there had been any more traffic around. Steptoe has a thread on it:

I'd check the battery if the ABS is playing up. If it's less than perfect then the ABS will keep "failing".
Although I don't mention it in the thread, an MRA screen makes a huge difference to the bike. Not cheap but worth every penny.
Sounds like a great service history - see if the stuff I list has already been fixed. Especially the clutch actuator.
Otherwise enjoy it. Looks fine to me - we ought to have an 1100 meet somewhere in the South. Any decent bike friendly caff's around the Hants/Wilts borders?
