Read more to get the link to the 2010 Harley-Davidson motorcycles approved by the State of California.

As of July 1, it looks like my speculations about a water-cooled Touring bike are wrong, but it was fun to guess. But there is still the question of a water-cooled engine sitting in the EPA testing lab for 2010 approval. Is it still possible that something new will be announced at the Dealer Show in July.
Just go down the list to the Harley-Davidson bikes. But if you are interested, you can see all the manufacturers 2010 models.
There are no water cooled engines on the list (yet?). The engines remain the same TC96/103/110. The Sportster seems to be only a 1200.
