I used PCX 2012 for 10 years and I will continue to use it in next 10 years. That's why I buy this to upgrade to digital meter days. I have not install it yet as my mechanic booked me in the end of month, but I know it will be awesome !!. The manual comes in Japan, but I believed from picture telling color of the wires, my mechanic should have not much trouble figure out how to put them together. I also but the additional water pump attachment, I like to make the most utility from this thing. The additional attachment was written as kitaco item number in the manual, I search google and somehow it bring me to webike store and it is here : webike.net/en/sd/372711 It is not a cheap but I believed this is the reward I and my ride deserved.
