Those Showa fork bottoms are the real thing, as you can tell from the tool-path marks from their milled-from-solid manufacturing. Remember that the brake torque that regularly lifts the rear tires of these bikes off the ground on corner approach has to pass through these parts. One of the cylindrical extensions probably contains a gas accumulator whose pressure prevents oil cavitation, and the other contains the valve shim stacks. The hydraulic line to the caliper has a quick-change connector, and you can see a front-wheel speed sensor at 7:30 on the yellow circle.
