1150
Can't really help you with the clutch issue, but the ABS lights fail to go 'off' if the battery is not in good condition. If it is not holding charge, or not been charged for a while it does not have enough juice to run the diagnostic tests.
Charging the battery should help you check it out, while you are at it, check the level in the battery, as the battery on the 1150 is under the tank and therefore a pain to check it often goes unchecked for a long time. A lack of fluid in the battery would be all you need to cause the problem with the ABS not setting itself.
If you have bought from a dealer take it back and get them to sort it.
