I've contacted Mohard Racing over last few days, they are unwilling to "design" new rad guards for a 2013 WR450F. They dont have the time in their schedule, and they say the cycle "is not a popular model" (ie: not enough market to sell to). They currently make and sell rad guards for a 2012 WR450F. I told them I would be their gunnea pig for a test fit of the 2012 guards onto my 2013 model. Anyone know why this would not work out?
