Change in 2006 model except for color : tyre valve change to "L" shaped one.(what a minute change..)
And Lowered seat was added as Kawasaki W650 option. This is different from W400 seat(as long as I heard).
*Kawasaki Original Low Seat
22,470yen

I wish Kawa increase more color options.Estrella has 3,W650 has 2. Hopefully 10 or 20 colors!.
