I'm pretty sure the new 2006 YZ 450 is a RED sticker only bike, but is there a way to make it a GREEN sticker easily? I doubt it, but thought I'd ask. So RED means you can't ride the desert from what months? (i.e. Octillo wells, etc?). I guess it's ok in the Winter season? Sorry, I've been on a Green sticker bike so the RED is new to me. Thanks!
