I've had a Zumo 400 for the last 8 years and swear by it. A good coating of ACF50 on the pins works a treat and it is possible to replace the connector if you can track down the parts.

The Zumo 400 is limited to UK only. To get full European mapping you need to move up to the Zumo 500 or above.

I have a Ducati Monster as my 2nd bike and use the Zumo on it as a speedo as the standard instrument cluster is really hard to read in daylight.
