Well... 60 words / minute on the old keyboard doesn't hurt for things like this, so I will keep it coming! Back in the day, they made us take typing class in Junior High.. I am sure some of you guys will remember typewriters, DOS based computers, no cell phones or answering machines, and a big gaping hole in your dashboard for that 8 track tape! And I am only 41! But I digress...
Sat on a RK with 518's yesterday when I picked up my bike from the dealership (I swapped out my V&H MO's for HD SE Touring Muffs / Dyno'd.. awesome!), and these bars didn't have the wheelbarrel effect of the 508's, but the 1.75" less pullback combined with it's low height created a downward arm angle as I was holding the grips (sitting in my upright position). I could feel my shoulders 'dislocate' forward in order to have a relaxed hand position, and the verdict was in right then and there... they would eventually start to bother me if riding in the upright position / leaning towards the backrest.
It must be said that my low back is not the strongest it has ever been, and I could use some yoga / pilates (don't make fun.. there was a professional football player in the last class I went to, and Muhammed Ali was a Pilates devotee) to tighten it up a bit, but riding more upright / leaning back works best for me, and I am sure will help me keep my posture as I get older (I don't want to end up as one of the guys who are so slumped over that they look like an upside down U when they walk). More info and pics to come... of my 513's, and then the 502's when they go on in 2-3 weeks. Just ordered my Magnum Steel Braided Lines, and next year, when I have a bunch of chrome cash, will switch to the chrome hand controls. You think 2011 will be watercooled? j/k
