I have a 2013 SM which I put a corbin on (I bought it used) Also 5'8" and am comfortable reaching the ground. First mod I did (before delivery) was had the dealer put Avon Distanzias on, because i travel offroad as well. I have bought the seat concepts before and they are a great product. If you can make it to Timmies (leslie and lakeshore) this thursday on bike nite i will be there from around 8 to 9, parked on the lawn. After that we head out for some in town twisty riding. Post here if you think you can make it, I will watch for you.
