I am researching the CRF450R dual sport kits also. I have a 2005. I bought the bike in CA for desert riding and recently moved to OR and want to ride the bike a few miles on the street to connect to the dirt. The main problem I am having is finding good DOT dual sport tires that fit a 19 inch rear wheel. I would like to stay with the stock wheel after all the other expenses that are accumulating.
