It has been fitted to the first batch to come out of the factory to speed up production, but if you are ordering a bike for delivery next year, you should be able to order one without the ABS if that is what you want. The first buyers didn't have that choice. I think the cost of the fitment is in the region of £750.
Bob's right. My original order (delivery Jan 05) was without ABS - with a considerable saving. I believe the earliest non-ABS bikes were due to be built/released in Dec. I picked up an ABS bike well early in the end.
