One thing that keeps being overlooked in this conversation. If you ride your Rocket to the limits, i.e. try to ride your 800 lb motorcycle like it is a squid bike, then don't go darkside. It's not for you.
However, if you are a less aggressive type rider, primarily a commuter/tourer, then darkside is very appropriate. 50,000 miles so far with no issues. Riken Raptor 225/55ZR16.
You may have help me choose the dark side when tire time comes for me. I have my K1200 for spirited corner carving. Prudence's charms are elsewhere to be savored. 50,000 miles without the redundant trouble and notable expense is just the kind of accessory to those charms.
Any plusses/minuses/considerations to 50 & 55 aspect ratios other than a nominal change in speedo calibration and seat/ride height?
