For the past eight years (post surgery), I've been very weak due to extreme muscle loss and other neuromuscular issues. That has kept me from enjoying my 2K I/S.
I always felt it to be clumsy at very low speeds and especially after "going to the Darkside". The CT has it's merits and I think if I were stronger that I'd stay with the CT for touring purposes (highway riding), but I am not physically able to ride as I have in my younger days.
After long and extensive research I have decided to try using "Sport Touring tires" on my I/S. The front is extremely different from what most Valkyrie owners are currently using, but I'm not typical. I had a set of Continental "Motion" mounted to an extra set of wheels that I had. The tires were purchased through "Iron Pony" for $199.00 a set (cheap!).
I polished the wheels, added 90 degree "patch boy" schrader valves, Dyna beads, and then painted the cut outs in satin black. I'm also replacing all of the axle and fender hardware with SS fasteners.

The weight of the Conti tires is so much less than the Avon tires. That will reduce the unsprung weight, resulting in better suspension compliance and reduced steering effort at low speeds. The narrower tire has far less rolling resistance, and that will aid in parking and moving within my garage.
I know that some may think that these tires (sizes) might look a bit odd, but I believe that the reduction in steering effort and lower rolling resistance will far outweigh any negative aspects. If I'm right then I will be riding my (3) Valkyries a lot longer.
