So the good news is, if they do fail, you only have to fix them once. I'm not sure if the 450's have the same issue or not.

If you want sweet transmission ratios, then you need a late '90's DR350. It's a tad heavy, decent power, but no KTM, but it has one sweet trany. I've not ever ridden a 4-stroke that lugged so well.
I have an '05 250x.

04-05 right intakes on these bikes zero'd quickly for some folks. I put Kibble White stainless valves in on mine and now have over 3,000 miles on them. They have not moved at all.

If he gets the 250x be sure to do the CCC mods (open airbox, rejet, accelerator pump mod, exhaust baffle drill out) to get the most out of the bike. All nearly free mods that make the little 250 haul just fine.

Go to TT (thumpertalk) to read about the CRF valves......

It's easier to find model specific information on their threads IMHO...

Ride the bike until the valves zero, then put in Kibble Whites valves/springs. Have AS Racing do the work, he's THE most reputable shop for Kibble Whites and works through CRF's Only website. His prices are more than reasonable, turn around time is quick, etc. When you get the new valves, consider dropping in an 07R head with bigger intakes/exhaust ports for a bit more hp. Then, while you're their, drop in a Hot Cam Stage 1 for more mid range ooomph and easy 3rd gear wheelies. All this if you're the tinkering type, like myself.

Working on the CRF's motor is really easy, simple, and quick. It's like chump work compared to the million bolts on an old XR. I could put a new head on a CRF in a couple hours or less, that easy.

Buy an 06 or newer! I have both 250x and 450x which are 2006 models. The 250x was
a kid's bike until I put on a Jardine full exhaust. Now, the motor winds up and the suspension is plush and near perfect stock for single track. I haven't done any airbox mods, wire clipping or even jetting and it runs great!
On the other hand, the 450x has abrupt acceleration much more than any KTM that I have ridden and somewhat harsh suspension but it is pretty damn perfect (within one click) for desert riding the way it is. I just took off the stock exhaust and put on a full titanium exhaust. I feel like it was a mistake to mess with a perfect running bike just to turn it blue but it is a matter of patience, I guess. I weighed 170 pounds last summer but probably weigh more after winter feasting. The only people that really bitch about the 450x in the desert weigh 200 or more

We've all become a little spoiled with all the variety out there.
To argue over a wide ratio or close ratio, 250,400,450,525,
carb over FI, inverted forks over standard..... blah, blah, blah.

Just about anything you buy out there is going to be more bike
than most are riders. The average guy wouldn't know the difference
of any of the above mentioned debate if you handed him the bike
and said "Go try this".

I'm old school and can enjoy anything with a motor.

I would still say so much of the cutting edge performance available
today is wasted on egos larger than their riding ability. Just sayin'

I'd rather ride a bike with shit suspension and brakes as a first dirt bike. That way you learn how to be smooth and ride a pos. A setup bike can he new dirt riders into a world of trouble.

At one time I had 6 Hodakas.

Linesman boots were the bomb back then.
Football front guard wrapped with duct tape made a 3/4 a full helmet.

I think I still have the manuals and repair tools for the engine.

That's a good logic. What's your suggestion? Or are you telling me that the 450XC is a bike with shit suspension and brakes?

No, sounds like he is saying it would be a bike with incredible suspension
and brakes with a shit rider.
