I know there's always a compromise.

At this time, only one bike for myself is practical. We also have my daughter's 19 YZ250F that I ride quite a bit.

I really love my YZ450, it does great in the desert and MX of couse. But I've been riding woods more lately, really rocky terrain. The rocks are just about the only place that I don't enjoy this bike. Its just too firm, I get deflected constantly, which starts to wear as the ride goes on.

So it's time for a decision, re-valve the YZ450 so it does better in the rocks, or sell the YZ and pick up a 2022 FX350.

I'm still not totally sold on air forks, but I know they've gotten a lot better for 21 and 22. Also I think having less power and torque will be better for the arm pump I constantly get.

I'm looking for advise from anyone who uses one bike as a do it all. I probably ride about 60% desert/20% moto/20% woods.

I'm thinking with a revalve the YZ450 could still be a really great all around bike.

As a current owner of a 21 150 sx and a 19 350xcf and former yz450 owner.07 and 09 .I say get a 350.I say this with zero hesitation..Unless you weigh 400lbs or ride dunes.

I weight about 175#s

I don't want to have to spend a bunch of money on the FX to get the suspension to work. This only makes sense if its good out of the box.

I did not love my 350 here in the desert.
It was mostly awesome but because of the air forks I hit the ground more than I had in a long time. The front end let go a lot on corner entry. It was very unpredictable coming into hard pack corners with hard edges like at montessa.
I highly suggest riding one before buying one.

Have you played with the wifi tuner on the yzf to make the power more manageable? If not, try that first to see if that improves the bike for the rocks

I've messed with maps a ton. I have a pretty mellow map in there now that I like a lot. But its not the power that makes it tough in the rocks, its the suspension, and maybe gearing a little.

I've ridden a KR 350 at Rainbow for a few miles. Its felt pretty awesome. But it was not deep sand. The 21/22 forks are supposed to be vastly improved. They felt almost as good as my YZ, but again it was a short ride.

You will hate the stock forks if left untouched in rocks. Deflection city. I have KYB kit PSF1 air forks on the way for my 250xc tpi for just what you are complaining of on your YZ450.

You already have the YZ, revalve it, give it a chance and go from there. If you don’t you might always wonder if you made the right choice. IMO

This.

Although the suspension on the 21 and 22 KTM bikes is worlds better than the 2020 and before, your KYB stuff on your YZ is better overall.

You’ve got all the right parts there for a great do it all bike. Have a suspension tuner drop in the settings from a YZ450FX and you’re pretty much set. Might also look at the G2 throttle tamer to help with jerkiness at low speeds. Plush suspension with a less twichy throttle and I bet your arm pump goes away.

The truth is that if you’re looking for more comfort in the rocks, a lighter bike and air forks are a step backwards from what you already have.

Revalve the 450. The XACT fork is gonna need a revalve if you get a 350. It’s worse in the rocks than your KYB’s.

Thanks for all the info guys. I have a local suspension tuner that used to work for Factory Husqvarna GNCC, everyone who has used him raves about the results. My 450 only has 85 hours on it and has been perfect since new. It will save me a lot of money just to keep this bike and make it work.
