I bought the Mustang Super Touring saddle. It's 17" wide, moves you back 1.75" and up about an inch.
The Super for a 2007 will only go back 1". We wanted to let people use the backrest kits, so we limited it to that far. For 2008-17, yes, 1.75" is typical.
Height depends on frame height. On 2009 models I expect a Super to be lower than on a current model as a general rule.
I to have an 07' RKC. I'm a bit long in the legs as well. I like the seat and riding position just not where my feet want to land. Has anyone moved the floorboards or controles forward? I like the floorboards so not wanting to go with forward controls set up. Just relocation.
