I am waiting to have an OP for my CTS in the mean time I went down to a local gun shop and bought some fine lead shot. I bought some 10mm clear plastic tube from my local Hardware store and made my own removable lead bar snake. I would say I have lost 80% of my vibration for NZ$12. I then put bar raises on which cause me to sit slightly more upright, this reduces pressure on the hand. These mods are both easily reversible and allow for fine tuning. I can now ride for 3-4 times as far before my hand says " you have enjoyed your fun, now go home"
For those without CTS they will not understand how quick you hand starts to get painful even with a little vibration.
