Thanks for your first impressions, DSC. What LED option did you get? I've tried a few and the only one I liked is a GENSSI LED I found on eBay. It's really bright, provides a nice solid beam and has a low beam cutoff. Here's my review -

I need to do a write up on the progressive shock. I tried hard to like it and adjusted the hell out of it, but it was way oversprung, provided almost zero damping and rode like a hard tail. I switched back to stock and after setting to zero preload, my RX3 rides better than the progressive. Others love the progressive shock, so maybe I just got a bad one.
You aren't the first to notice an issue shifting to 5th and 6th. Mine does not have that issue, but maybe it only affects some 2016 models. I'll be interested to see your extended reviews as it breaks in.
