I have an Acid Green. I like the red/white/black one best of the current colours. Good choice.
I have Woodcraft frame sliders and spools, Pazzo levers, Vortex rearsets, BMW seat cowl. I kept the stock exhaust. The levers and rearsets were big improvements for me. Most S1000RR owners use the Attack rearsets but I prefer the simple profile of the Vortex. The Woodcraft sliders are subtle, which I like.
I have 20,000 kms on mine so far and love it. Handling is precise and quick. Brakes are extremely good. Power is grin-creating.
The ABS is not too intrusive. I almost never feel it come on for the front, not often for the back. Traction control also is not too apparent unless you're riding at ridiculous pace through corners, other than wheelie control which is pretty constant with any strong throttle inputs. I don't find it annoying as it is pretty smooth. The shift assist is very fun and makes a very cool exhaust note when you use it under full throttle.
