I run that on the '03. If it's an '06, try a 14/49 or 14/48 first.

I have 15/48 or maybe it's 15/49 on my 4 speed 04 YZ450F. It's street legal but I think it's still not enough for the street here. It's fine for all the roads if I'm under 45 MPH. I took it on the highway once and I was getting smoked. Top speed is much higher than 45 MPH but for continuous riding above 45, I think I might blow her up because the revs are too high.
I'm looking into poping a 5 speed WR450 trans in it. Anyone know where I can get one used?

Hey I forgot to ask, will a 16 tooth fit on the front sproket? Or should I just go way down in the rear like 2wheels-DRZ did.
