Attached a rear rack (Ibera Pack Rack) using the factory bosses, had to fab the rear stabilizer arms out of flat bar, and used spacers at the rear drop outs for better clearance. Mounts strong and sturdy, no vibrations or noise. Had to cut the right ergo grip to fit with the throttle. Used M-Factory (ebay, $59.00 pair) bar end mirrors that are sturdy, adjustable, and small but slightly heavier than most bicycle mirrors. This actually has a noticeable stabilizing effect to the front end handling and steering.
I know there are larger Ah batteries available after market that fit into the slide-in, the Samsung pack for example, still looking for a source other than ebay or Ali Express, where some sellers try to sell name brand batteries with generic cells from China.
