The 4 strokes (YZF 426 or CRF 450) have a more linear powerband and are easier to ride but powerwise and speed wise they are about equal.

Do you mean the power of the 426 and 450 are about equal or the power of the 2 and 4 strokes are about equal?

I mean the power of the YZF426-450 or CRF450 and their 2 strokes 250cc counterparts are about the same.

Ask Yamaha because around here we cant see any...A bit more low end torque maybe.

There is quite a bit of difference. The 450 is lighter, stronger, and has auto decompression so no starting procedure like the 426.

You have to run a starting procedure on the 426 or a 250f (before the 2003 models). It goes like(I had a 250f but, it's been awhile):

1) pull in the decompressor lever
2) push the kick starter aprox. half way down
3) release the decompressor lever
4) bring the kick starter back to the top
5) kick down

Once you do it enough you getto where you don't think about it but, it stinks when you flood the beast as you have to do this about ten times.

The 450 motor is noticably stronger than the 426.

I'm a bigger guy (250lbs), so should I be looking for a bike with aftermarket shocks so I can have them revalved for my weight?

HiFlyinRaptorRyder-

I was in the same spot as you. Bored to death with the raptor, and sick of piling money into it for minimal performance gains. Bought a crf450, and once I started riding it the raptor sat in the garage for 6 months until I finally just sold it. Talk about a whole new world! It requires a lot more skill. Actually, the 450 was WAY too much bike for me getting back into riding on two wheels. There was more than a few times that I was laying on the ground in pain, looking over at the bike wondering exactly what the hell I thought I was doing. But man, the power when you open these babies up is just absolutely awesome. It put the grin on my face that the raptor had promised it would do, but never quite delivered. I never thought I'd feel like I had enough power in anything I owned, but this bike has so much power, I couldn't imagine ever wanting more. Cool thing is, if I ever do, there's a 480 kit for the crf that would really make life interesting (approx $800).

As far as which is faster, the yz and cr 450's are faster than the 250's. That's been my experience with my piped crf450 against a lot of two strokes on wide open fire roads (From the bottom, all the way to the top). Kevin Windham seems to be proving that point now too. When it comes to the motorcross track and trails, it is ALL rider. There are kids on cr80's that will completely smoke you out there, so get what you like. If I was getting a 2 stroke, I'd would look no further than the yz250. As far as the 4 strokes, I bought the crf, but the yzf is an awesome bike too.

As mentioned in a previous post, you might want to consider how purpose built these bikes are. Technical trails get really hard on these bikes. You can't lug them around.

Two weeks ago a friend of mine came up to go riding. He's been riding dirt bikes for 25 years. He kept telling me he wanted to maybe get a crf450. I warned him repeatedly that the bike is very poweful. He was riding a yz490, and thought I just didn't know what real power is. We switched bikes, and he made it less than 100 feet before he looped my bike. He took off in first gear, hit second, opened the throttle wide open, and disappeared in a pile of dust. The bike scared him (2 broken ribs and a fractured leg). He's a good rider (well, I thought. I've since change my mind a bit. You just don't open a bike up like that if you haven't had any seat time on it), but these new bikes are insanely fast, with tons of torque.

Anyway, get whatever bike you like the best, because the chances of you riding beyond the abilities of the bike are slim to none. You will love any of them. And the suspension is great too. Stuff that used to make me bite down hard because my raptor was going to beat the crap out of me going over, I just fly through now.

Great choice in dumping the training wheels and going back to two!
