If you are on an 05 you may want to try a 52T rear. They changed the primary ratio in the tranny (made it taller) so you have to run more secondary to make it similar to the 03/04 gearing. I know a lot of people went from 48 to 47 on their 03/04's which calmed the beast down but made the spread between gears larger. I always felt like second pulled to far out of the gate and I was changing to 3rd to close to the first turn. By going to the larger rear I use second to cross the gate, grab 3rd and ride it almost exclusively with an occasional shift to 4th or down to second depending on the track and conditions.

I ran stock on my 03. Then I had an FMF exhaust and a 6oz flywheel. That made the bike real smooth.

15/49 on the 450. That's what the original question was about. The 250 has the stock gearing, 13/48. It's what was on the bike when we got it, and it seems to be OK for all-around riding.

In not sure what gearing to do also. MX Only 05 YZ450

I'm going to wait and see how it goes with stock gearing, before changing it. With the weather here in CT I might be waiting another month or so. For now, I'm just interested to hear what others are doing.

Running Renthal 13 tooth on front, stock 48 on back. The 13 on the front is like going up 3 in the back I believe, although some may argue. I'm considering going to a 49 or 50 on the back, since I ride more trails now.
