So it's been a while since I have been on here. I got rid of my 2000 426 when I got divorced over a year ago. But a couple months ago I decided I needed a toy in my life, so I treated myself to a brand 2012 YZ450F. This bike is amazing. I have been riding for 20+ years and this thing scares the s$%* out of me, but in a good way . I broke it in up the woods and it was hard to get used to the pull this thing has when cornering. Last weekend I put the paddle tire on and took it to the Oregon Dunes for the first time. Oh My God! This thing is a beast in the sand. I haven't messed with a single thing on this bike (besides suspension stifness) and I don't think it needs it. This bike is the smoothest, most powerful and all around perfect bike. Just thought I would give my two cents on the Bike. If anyone has a 2010-2012, and has done any mods to it that they recommend, I would really appreciate it. Also if anyone has the GYTR programmer and recommend it or not, I would love to hear that before I buy one. Thanks a lot everyone.
