If you go to the yamaha website and look up the specs for a yx 250 it will tell you I beleive.

Hope this helps.

The manual may have a range, it will probably say 11 to 15 psi or thereabouts.

Anywho the tire pressure isn't model specific. I wouldn't run more than 15 psi in any MX tire, and will usually run 11 psi, unless I'm concerned about the possibility of a pinch flat, in which case I'll go up to about 14.


Hope this helps.

the old saying is "if you don't know what to run, run 13."

11-15 is correct, 13 is a great guess for any condition. You should have a 1/4 inch ring around the rimnext to the bead that is rubbed clean by the tire flexing. Set your psi then go out and run a few laps. More area not enough air less area to much air. If your to light or to slow to get flex with 11 psi run a heavy duty tube to prevent pinched tube flats.

I've gone down to 8 in the back and 10 in the front when it is muddy out. Just play around with it and find what works for you. Anything more than 12 in the back and 14 in the front and it doesn't feel "good" to me.

Thanks for the info I will try 13 and see wha happens.

I run 14-15 psi at Paragon. It's real rocky and while the higher pressure affects traction/handleing a bit, I'd rather not get a pinch flat. Once was enough for me. 12 -13 psi is good other wise.

Rm guy I was at paragon about three weeks ago on my atv and it seemed like it was really rocky for the dirt bike. This was my first time there, was I just not on the right trails? :bang:

Yeah it can be tough on a bike but I like it. It can take some time to develop the right technique but after a while you can move right along. I don't go into the "extreme" rocky places but there are some that do.

The trick is to stand up some what neutral but keep the front end light, focus on where you want to go (not at the front tire), squeeze the bike with your legs and keep on the gas. Most of the time speed is your friend because you tend to skim over the rocks but it takes some practice to feel comfortable with it. Squeezing the bike really helps to keep it from kicking around and staying straight.

I am relatively new to the sport and some of those rocks are really intimidating. Dou yo know if Tower City and Rousch Creek are also really rocky?

i've been riding for over twenty years and the rocks are still intimidating.

I have riden them on my atv and even that was a littl crazy. The intermidate level trails at pargon are like a boulder field.

In the northeast, either you ride on rocks or you don't ride. Trail Rider 05'

Some rocks are fine, rocks to me are relatively small, but what I rode on with the atv was very challengeing and at times very hard to manuver, these were more like boulders
