WOW, I expected a major difference...but I didn't expect THIS. I remember how much I loved my 06 FLHT but this is the smoothest riding bike I've ever been on and the engine has no shortage of power. Since I only put about 300 miles on her today I haven't opened her up or run up the RPMs but seriously, WOW. To make sure that the bride is happy we bought a hammock seat and she says it is more comfortable than her TV chair in the living room. The sound system is great for what it is and I got the extra 2 year rubber to rubber warranty to bring it to 4 years plus the lifetime powertrain warranty. The only thing I regret is not getting any good pics of my Dyna's last day...
