Hello, I am looking for a used 125cc dirt bike. I am puzzeled because I do not know what I want, what would you guys recommend and why would you recommend it. Also where could I get performance mods, specifically suspension and which of the bikes have the most tuning capabilities. I've narrowed my choices down to Kawasaki kx,Honda cbr/xr, Yamaha yz, and Suzuki rm around the 2000-2005 range. I'd rather hear from people who owned one of the bikes but advice from any of the experts is welcome 

 

P.S I'm sorry for any mistakes like the wrong "sub forum" or grammar as I'm on mobile

Probably get more replies by asking this over in the dirt bike "what bike should I buy" forum..

For the KX, look at 2003+. 2003 was a new model with major changes.  The 2004 /05 got updated suspension and some orher smaller changes. 03 had the best suspension for trail riding, imo. Kawasaki made a very nice 125, probably the best.

Yz's and Rm's are a good choice as well, but I'm no expert on which years were best.  Between blue and yellow, I would go RM for a 125. 

The Honda CBR/XR you mentioned are not the same types of bikes. You meant to say "Honda CR", and I never liked them personally. Other people love them. 

What is your experience, and what sort of "performance mods" do you need? What riding type do you do? These are all purpose built race bikes, and for MX will work very well in stock form, after you sort the jetting and spring for your weight. They get more mods for woods, but its mainly about wants, not needs.

The mods will be moving this to "what dirtbike should I buy?"

I'm looking for suspension mods mainly after that I'm going to do some internals and maybe a rev box. I ride on dirt trails up hills and roads mainly. Thanks for the responses

If you are looking to "do some internals" and install a rev box on a YZ, KX, or RM, I think you may need to do more general reading about these bikes. Tell us a bit more about yourself, and your riding experience.

For me, none of the 5 speed 2 stroke bikes have ANY appeal.  As for suspension,  the two major players supply the suspension parts for all the mx bikes you mentioned.  There are shops all over that do suspension modifications.   You can google it and probably find someone in your area that is a suspension tuner.  We even have them in Anchorage Alaska.  I am guessing that your experience is just past zero,  so your needs to modify your suspension probably are not there yet.  The exception would be if you are extremely short.

If you want to buy the best suspended and lightest (and currently produced) japanese 125 mx bike,  that would be Yamaha.

      Hi there, i got me a problem. my xr400, about a week ago i heard a slight ticking in the right hand side of the head, the sound kept getting louder as i rode the bike to and from work. i figured it was the valves. so when it got loud enough to hear without listening for it i went in and checked valves for the first time in my life. did a fair job. in spec now. but as i didnt know much as it was my first time, in all my wisdom i turned the flywheel clockwise trying to find tdc. (Which isnt where it should be, not on the T marker) i heard a clicking/snapping noise when i did this, ive read now that it could have been the manual decomp? but now the noise is so loud its almost drowning out the idle. i checked the cam chain tensioner. its fully extended itself. is this my problem? or did i break something?

      I've wasted my stock pipe, but don't want to spend $200+ for a new Gnarly. Lightly used but not abused is acceptable to me. I believe the part number for my bike is 025087. I am open to other part numbers if it can be verified that it will fit my bike. 
      If it has a guard, I might be open to paying a little more for it. But I already have a brand new Moose Pipe Armor guard waiting to be installed, so it's not necessary. 
      Thanks in advance...

      Hello, gotta say sorry for my bad English in advance, im just a confused swede
       
      i have a 2010 kx450f and i need new spokes. a friend of mine have a set with spokes but he is unsure if it is complete . he had 30 spokes in a package i could buy from him.
      anyway, my dirtbike is 2 hours away from where i live right now so i need some help here. How many spokes are there on a 19" rear wheel on a original black rim kx450f-10?

      Here is my "new to me" 2006 CRF450R.
      Just did new valves/and adjustment as soon as i got her along with a new plug, and all fresh fluids.
      She will kick over first or second time no problem when shes cool. .. but if i stall it out after I've been riding for a while its an absolute nightmare to get her started again.
      either way I love the power of this bike. shes amazing. BUT next bike will have an E-start.... Im lazy.

      Today I blew/ lost a head screw on my new-to-me KTM 150 XC two stroke. The bike runs, no odd noises, but lacks compression. My friend and I ran a compression test after the ride. It read around 100-95 pounds. However, when my friend and I did this test, we did not replace to screws or torque them to spec, as one head bolt was lost. Could our reading be off? The P/O claimed a new top end... 
       
      Thanks!
