I sure hope the kfx450 proves to be reliable and durable. I have had some really bad experiences with my 2004 yfz450. Iv only been racing it, one full season and anything that could have possibly gone wrong with my quad has. I spent 2200 on rebuilding the engine when my wrist pin failed and another 1200, 3 months later when my tranny blew up. My dealer told me that somehow the second gear on my shift drum got starved of oil and got so hot, it welded itself to the drum. He put 4 tons of pressure on the gear and it still hasnt come off.....now i have to get a new drum and gears costing 480 dollars!......i hate yamaha! and i havnt even mentioned the other things that happened to my quad yet

I know the KX450F has been very reliable....i do, how ever, look for this to have a few bugs to be worked out. I just hope they're few and far between.

Not to put a plug in for yamaha, cause i'm thinking of switching to kawi too, but i had an '04 yfz that friggin sucked too and i hated it, but then i got an '06 and its been great! it was a world of difference between my '04 and my '06 yfz's

Just what bugs are u talking about?

hey guys guess what? YFZ450's do indeed suck....or maybe i just have incredably bad luck, but i just bought a 200 dollar radiator cuz my stock one had 5 holes in it....now my brand new radiator is leakin!!!! iv come to realize that yamaha are fasssst as hell but not realiable

 

[yfz450psycho]

Yes I to hope the first year models are reliable due to the fact I aready put 5k down on one

 

[cchrider]

I hope they are reliable also. But i race a 04 yfz. Has alittle over 2 seasons on it and it has held up pretty good. Of course there have beens some problems down the road but to me that is just racing.

You guys have to remember that the 04 YFZ was the first 450 to hit the market. They were out on a lim when making this new high performance machine. The 450 world owes a lot to yamaha. This is no excuse of course but it sure was amazing when it first came out. I have a 04YFZ450 and have had problems (rebuilt engine, and tranny) but overall it has been a great machine and outperforms most others still. I am in the market for a new one which is why I am a member of this site. Im not trying to be contentious just share a different point of view. I am not biased towards any particular company but just a serious rider who wants the best.

That's not true. Cannondale was the first to hit the 450 market back in 2001...

i have a 06 yfz and i hate that thing basicly everything inside the engine and trans has been replaced on it. at 6 months old the crank berring plate bolt came out. messed everthing up. sence then i have had to fix everything there is to fix on that bike. i think yamaha is getting cheap on quality because a have a 01 banshee and i have never had a problem with it

Yes you are right, there was a cannondale 450 but we can see how well they did! I am reffering more to the main stream of 450's that we see now that are all built very similar and for the same purpose. Back in 2001 there was not a 450 racing class like there is now. As far as I am concerned cannondale had nothing to do with the 450 world we see now. They tried but failed.

that is such a ridiculus comment. Motosport companies aren't shoe manufacturers, if they were they would sease to exist.

To quote a Honda salesman I was talking to when considering a TRX 450r, "the higher performance you get the more chance of things going wrong" which is totally true. One can't expect the same reliability out of something built for performance then say a utility quad or beginer quads.
Honda's I beleive have the best alround reliability when considering all the different products they make but yet I have 2 friends that have TRX450's and they have both had the same problems as my YFZ.

One last comment, poeple can't blame manufacture's for poor reliability and craftsmanship when they fail to take proper maintanence of there machines. This is the leading cause for trobbles in the motorsport industry. Even this site in 6 months or a year will be covered in "what piston should i get, mines gone", or how do you split the cases", "my engine is runnig rough" or similar threads because despite how reliable these new 450's are, they are going to have problems. If this does not happen I am willing to admit that I am wrong. I guess we will see. If this is the case, I will never ride another machine then the KFX 450.
