DanDiego, did you ever get enough orders together to get a discount? I'm interested in buying a Kaoko for my R3. I previously tried out the FlipMeister version but swapped bikes with my brother one day during a trip and forgot to tell him about it. He really freaked and between the safety lectures from the other senior riders and his reaction I decided to remove it.
All I really want is a friction lock that I can use momentarily to shake some blood-flow back into my hand during long rides. I use a CrampBuster and love it, but my hand tends to go to sleep sometimes and a few seconds of shaking some blood back into it does the trick, so I just want a simple one-handed solution.
I installed a $40.00 Universal Vista Cruise, works great, but had to make modifications to get it to fit that are just...well, southern engineered and ugly.
