I just bought a WR450 and to my surprize I'm going to have a Red Sticker. I thought Red Stickers were for two strokes. The dealer said if the 8th letter in the VIN # is a 3 or C then you get a Red Sticker. I've been away from the sport for around 8 years (kids) and am now getting back into it with my whole family. I'm really surprized by the Red Sticker. They use to not want us to ride during the wet season because we eroded the trail. Now they want us to ride in the winter because of smog. This is outragous. These CARB people are the same ones who didn't see the significance of MTBE being water soluable. And are there really enough dirt bikes to really effect smog. I think an ounce of ethanol per refill would go farther in improving smog. Especially for the freeway crowd. O'well I guess its back to battling the government to get our fair share of ride time and space. Off road riding is an educational and wholesome sport. I don't think we should allow people to deamonize it. I can't think of a better way to explore nature and experience it. It would take days/weeks to walk through the forest, and still not see what an off roader sees on a typical ride.
