what sprocket sizes are you guys running

[brighteyed]

I hava an 05 yfz 450 and am wanting to gear down so i can have a little more bottom end. I suppose i should go down a few teeth in the back. What would you guys suggest and what are you guys running.

You need to go down a tooth on the front or add teeth on the rear. Taking teeth off the rear will give you more top end.

I have an 04' YFZ this is what I did. I went up to a 40 in the rear, down to a 13 in the front and bolted on a full set of Mudlite tires. 22's on the rear and 23 8x 10 up front. The trail riding is gonna rock!

I have a 450r and I run 13t up front and stock in back and I love how it feels. (I ride trails)
