I dont think he said they dont fit, just that cant mix them with a servo/abs unit.
"An ABS unit (from an 1100 or 1150) is absolutely non compatable in any way shape or form with a servo/abs unit."
However Littledumptruck was talking about removing the original servo/abs unit and fitting an earlier non servo abs unit which surely would be possible, even if expense may rule it out, so Steptoe's reply does not seem to answer the question he asked.
Be as surprised as you want -
The whole loom must be changed,(and the switch gear as the plugs are different) and you can't use a twin spark loom on a single spark bike, the ABS sensors are different, the brake light switches front and rear, the ABS rings on the wheels.
And no doubt a few more things that i haven't thought of in the 20 seconds it's taken just to think of the obvious.
