My 2004 Super 9 is liquid cooled (in USA) and I believe they were for a few years after that. I have never had any problems with the cooling system....very simple. A water pump and a radiator.
1000km is very low mileage. Mine (purchased in 2005) has about 13,000km.
There was a recall (check the Kymco website, it should be listed) for bad engine mounts for the 2004 year. The housing of the engine near the mounting point can crack, the rear wheel will let loose, and your scooter will be running sideways! Check the serial or engine numbers to see if your scoot qualifies.
I never received the recall notice as my bike had sit at 2 different dealers unsold. So mine catastrophically failed while I was going 48mph down a bridge. Very scary! I had it towed to the dealer and the fix is entire new engine/trans. Paid for by Kymco 3.5 years after I purchased the Super 9.
If the serial numbers match the recall numbers, Kymco might still replace the engine as I'm sure they don't want the dangerous ones on the street.
Other than the engine mount failure, the Super 9 is a great ride! I still love it.
