2005 Yz250?

Hey guy's/ gals,

I'm looking at getting a newer bike here very soon, and seeing as I'm a Yamaha guy, I'm looking at the YZ250. I'm looking at some nice used 2005+ models, the ones with the aluminum frames, but have read that the 06 and up are the way to go due to the better suspension?! How much better is it? I will be using the bike for all around riding (woods, hills, jumps, but not really for track use) I'm 31, and 165 lbs. Is there any reason to get the 06+ over a really nice 05? I currently ride a 01 YZ125 with hand guards, skid plate, and I find it works great, but I just need a bit more.


I'm in the same boat as you, got an 01 yz125 but I'm looking for an aluminum framed yz250:)

Anyone else? I thought this forum was filled with YZ250 experts?

You have to be going pretty fast to notice the difference between the SSS (06+) and twin chamber (05) suspension. The 05 works awesome for offroad. My MB1 tuned '05 suspension was more compliant off road than my friends stock '07 suspension.

Unless you are an expert or an avid track rider get yourself the 05. I recently bought an 05 250 that had 2007 suspension on it for $1,700. The reason why it had the 07 suspension was because the previous owner liked his older two stroke suspension more than the newer SSS. Personally, I like the SSS but I ride tracks mainly.

You will like the low end power of the 250 a lot more than the 125.

I'm sure I'll like the power more...I ride my buddies RM250 and love the power it makes. Right now I'm trying to decide on a 450 or a 250 two stroke...

I just got a new to me 05 YZ250 and am lovin it. The suspension had already been sent off by the previous owner and it works extremely well. I am very happy. It it is the best bike I have ridden in my short and humble career. I don't ride fast or hard enough to know the difference between suspension. I have heard that revalved & properlu spring 05 stuff is as good as the newer SSS stuff.

I like my SSS Suspension, works better then any stock setup i've ever ridden before, but a revalved and properly setup suspension will work just as good as the SSS.

i also tend to find my SSS a little rougher for offroad applications, but then again it's setup for the track not the trails

On the '05 fork you basically have position sensative dampening. the '06 fork moved to speed sensative dampening.

On the '05 you are more confined as to what type of riding you like to do. The fork can be set up for plushness or for agressive type riding. The fork does a good job at either, but probably not both. The midvalve on the '05 fork tends to get harsh with high speed compression spikes, but a company like smartperformanceinc can help with that.

The SSS fork is able to be plush, but can switch to agressive riding due to its dampening being speed sensative. The SSS fork will work better over a wider range of conditions than the '05 fork. The SSS fork will allow you to run much softer dampening while still retaining big hit capabilities, and that translates into a better overall ride.

The first thing I noticed when I rode the SSS is its much better at taking big hits without bottoming hard. My first ride out I blew a timing section and came up short on a little double and with my old forks it would have sucked, but the SSS took the hit without jaring my body as much as I was expecting.

The '05 fork was great in '05, but suspension evolved in '06!

For the price difference between a '05 and a '06, which is nill, I would try and find an '06.

Give this thread a read, it answers your question better that I can.

      Hey guys, 
      I've used this forum as a "guest" for awhile now and I thought I'd share my build now that it's all coming together.  The primary purpose of this project is to help me train for roadracing my 2009 R1 at lower speeds as well as giving me a cheap alternative to racing the big bike. 
      Here's what she looked like when I picked it up from a local shop.  Paid $800 cash for the bike as you see it with 17' rims, FMF pipe, EBC 250mm front rotor and clip on handle bars.

      Fits PERFECT!

      Shake down run at the Herrin Compound last summer:

      As she sits today:

      i bought my yz125 from a dealer and they said that the clutch was broken so i bought it and it worked fine it would run move and everything and then it started to act up and now only first gear works barely though. when you put it in first it acts like its bogging down but its not and when you go into gears 2-5 it wont move i dont know whats wrong with it im assuming the clutch is slipping or something if you know please leave me a comment

      Hey guys, I have a 2003 cr125 I bought a couple weeks ago and I'm having a problem with it. The spark plugs die every about 15 minutes, with hotter plugs it will last about 45 minutes. I herd that if the timing is off it can over heat the plugs and burn out the the resistor. Is there any truth to that? The reason I thinks it's not fouling is because when the plug dies it gives no spark no matter how much you clean it, And it shorts out.

      Hi all, First post here. I need some help.
      Ive just bought an 05 yz 125 for a good price but it needs some work. One of the forks has some pretty severe pitting of the chrome on the stanchion towards the bottom near the brake caliper mount.
      Ive found a pair of good condition forks from an 04 yz250 for a very good price, from the research ive done its seems that both the 04 & 05 forks are 48mm but are different, with the 05 fork regarded as being better than the 04, but not as good as the 06 + sss forks.
      Im looking for the cheapest way to get me riding, Will I be able to make the 04 forks work with my 05 triple clamps, brakes, wheel, axle, spacers etc? If not does anyone know what hardware id need to make it work?
      Finally, as a last resort, does anyone know if i could swap the stanchion from the 04 fork into my 05 forks?
      Thanks, Andrew

      I bought a 2006 YZ250, have ridden it 5 times.  It needs some tuning, but I am not sure I'm keeping it so don't want to spend much on it.
      Has fmf gnarly expansion chamber and turbine core silencer.
      I ride about 1000 feet above sea level.
      I'm going to clean the carb and check the jetting.  What is a good jetting for me?  85 main jet?
      Also check the reeds.  Is there a big difference between getting aftermarket reed cage and reeds or just getting a cheap aftermarket set of reeds that fit the stock cage ie.  Boyesen Power Reeds?
      The other things I'm going to do is permatex all the joints in the exhaust system and a compression test.   It was 220psi 5 rides ago so I'm guessing itll be fine.  Its bogging a bit but I'm thinking its carb and definitely exhaust joint related.  
      Let me know if I'm overlooking anything that could make the bike run crisper and more bottom end without throwing much money on parts
