No cables here.....It also looks like two small cables/tubes crossing over the clutch line. Could that be the ABS lines?
Looking closer I do think I see something that could be a braided cable right next to the backbone, but its hard to tell what it could be.
Here's what I got from AMA Test on another thread:
And, there's another advantage to electronic throttle control for a company known for styling. No cables means a cleaner look for the handlebar. The electronic wires run inside the handlebar. The other big news is Harley's new ABS system, which is standard on the Road King and Ultra Classic CVOs and will be a $795 option on all regular Harley touring models and VRSC models for 2008. It's an all-new system for Harley, and some wet pavement during our one-day ride provided some opportunity to prove that it works. The Harley system maintains separate operation of front and rear brakes. Steel braided lines run unobtrusively from both master cylinders to a controller unit located under the right side panel, then back to the brake rotors. If the wheel sensors detect lockup, the control unit pulses the brakes up to seven times per second to prevent the wheels from locking up. As with the throttle, Harley paid a lot of attention to the styling, as well as the performance. You have to look carefully, and know where to look, to see any visual evidence of the ABS system. Not only are the additional brake lines well hidden, but Harley also put great effort into making the wheel sensors unnoticeable. "It's totally invisible and that was an important part of the system," said Harley Director of Product Communications Paul James. The sensors operate using magnetically encoded rings in the wheel bearings. Harley showed us the parts to demonstrate how they work. The two metal rings look like thin spacers. I let them clamp together by magnetic force and turned one with my hand. The two rings "click" in steps as the magnetically encoded spots interact. That's what sends signals to the ABS control unit without the need for a big, external sensor that would detract from Harley's traditional styling. Looking at the wheel alone, there's no way to tell if the motorcycle has ABS or not."
