The RG I test rode was a stock 2012 RG. Maybe I'm ignoring the height because I like RKs. I did stiffen up the rear springs on my RK about 10 turns.
The mailbox windshield directs the wind right past my ears. Even a full face helmet didn't help. The noise is so loud that over 30mph the lowers mounted speakers and saddlebag speakers are useless. Now with the windshield off my 2005 RK on the 2013 CVO, the sound is very good, even at 80mph. The mailbox windshield is too low for nighttime riding when bugs come right at my mouth and are not deflected by that windshield. I've never had that problem with stock windshields. I've ordered a new one for the 13, so the 05 can be sold with a stock windshield.
My personal preference is that the handlebar mounted turn signals make the bike look like a cruiser. I don't like them on my RK. I don't like the yellow lights in my peripheral vision at night.
When I had 1500 miles on the 13 Anniversary, a dump truck must have bounced a rock onto my headlight, shattering the lens and leaving a 1/2" hole in it. Rain on the way home would have shattered the bulbs too. With the Aux. lights, I could continue to a safe place. At night on the Interstate, one headlight is not enough illumination for me. I've already put my LED headlight with daytime high beam Kisan Modulator for safety. The Harley one works on low beam and won't work with an LED headlight. On low beam, the headlight is so dim that visibility is worse than no modulator. I got a crimping tool ($30) and pin removal tool ($10) off amazon.com so I can properly wire the Aux light kit to the connector. I do have to remove the headlight nacelle to access the connector and pull the handlebar turn signal wires. I choose the Custom Aux lights 69818-06 because it includes the trim ring and wires long enough for a complete install, not the other kit that butt connects to existing wires for those that have a stock RK and want to replace stock with Custom lamps. The bullet turn signals look great under those Custom Aux lights.
