I come in peace.. I just bought a YFZ

[Don400EX]

I have had my 400 EX for a month or 2... (havnt had a dirt bike, or off road toy in 10 years) and have not been real happy with the power that this thing puts to the ground.
I went off the deep end and bought a YFZ 450.
I am a honda fan.. but I must say.. this quad is a freak.
I am going to guess that my YFZ has a minimum of 50% more acceleration, if not MORE.
My YFZ is stock, the EX400 has White bros FULL pipe, and K&N filter.
Anyway, I am not sure if I am gonna keep the 2003 EX 400 and let my girlfriend ride it.. I guess it depends on if I get any offers to sell it.

I havnt had the YFZ out in the trails yet, but so far I can tell that the power is incredible, the turning radias seems to be superior.
I am not flaming and dont expect to receive any.

lol damn. I heard nothing but good stuff about the 400ex, i go out and buy a brand new one and all of a sudden they are at the low end of the quad rating. lol guess its a good start bike for my first sport though, and besides i love it.

congrats on the new bike don

i'm in the same boat as you gearhead, except i didn't buy a new one. but i just got my 400 last summer and but some money into it, and i have already outgrown the power, suspension, etc, and am ready to get a yfz.....hopefully this spring. i was wondering about how much i could get out of my bike, here's a pic, tell me what you think, i was thinking prolly 2500 or a little more. and i'm gonna do some pc'ing here shortly, so that'll help.

Have any of you guys thought about the trx450r??

BTW, your 400ex looks really nice...

I think everyone understands. I love my 400 and I'm still upgrading it... while a lot of others are moving on. The 400 has plenty power for me. Right now anyway.

So, its okay as long as you don't try to suck the brain fluid out of our heads like this guy did in the movie.

The 400ex is a blast to ride and If you feel like you need to go faster get a 450r and put a pipe on it and you will fall in love.

I just bought a new 05' YFZ a few days ago too. I had a 416ex with a ton on money dropped into it. The 416 doesn't even come close to the power of the YFZ. I didn't think it would be that huge of a difference but I bet the 450 is putting 50% more power out. I did buy the YFZ new with a BUB carbon fiber complete exhaust and K&N installed so that helped with the power.

My friend has a YFZ and he has the a-arms replaced, 3 stems on it and had carb problems. My other friend sold his YFZ and got a 450r he had nothing but problems with it. He loves the 450r. Oh yeah I have to say they race gncc/mhcs. I still think the 400 EX is an awsome bike mostly (I BELIEVE) the YFZ feels so much fast than the 400 is because of the power delivery. The yfz is like a 2-stroke and the 400 is very smooth on the power delivery. I like the smooth power in the woods it helps you from tiring out in the long 1.5-2 hr races. That is just my two cents but yea the YFZ is faster.

I thought the yfz's were a bunch of hype till I rode one saturday.
My fully built tc 426 power wise is real similar untill you hit the top end the yfz just kept going. Its motor was stock with an HMF pipe.

Handling wise both my quad and the yfz I rode had extended everyrthing and shocks. But the yfz seemed to handle better being lower. And it didnt seem to wear me out as much. Being a little easier to throw around cause of the weight.

I was going to call BS to the weight difference, but I checked. YFZ 350# 400EX 377# Working an extra 27# may wear you out after awhile. I will not buy the YFZ because Yamahas lack of customer support and the R needs a starter. IMHO....
