First, sorry to write in english, I am from Poland.
I have almost new Rapid Bike 3 computer for moto morini, with the cables of course. It was installed in my own GP 2009 for a few months, but later I had some electrical gremlins (broken 5A fuse, if you know the issue) and when looking for the problem I dismounted RB, put it on the shelf and forgot about it.
It looks almost like new, was on the bike maybe for 2-3kkm. I can send the photos if someone is interested. Price is 160EUR, shipping included.
