Dude don't mind Art he is ONE GRUMPY HOMBRE
And his bikes are always perfect and never break Even when they are at the shop getting worked on
Anyway I have a 06 , and 07 like yours and some saddle time on the roadster. The transmission on the roadster does shift a bunch easier. Maybe they changed some of the sliding tolerances. Its hard figuring without tearing the 2011 transmission I have apart along with a older one to compare. I will also not since the roadster shifts much better I have noticed shifting dogs getting bent since the roadster which is something you never heard of in the older days when bikes needed updated trans work.
On a side note for humor you should have seen me shoving my heal into the pavement on the roadster looking for the heal shift
After having over 70,000 miles on floor boards I would guess it looked kind of funny
