Stock tire size vs. 120/100

Looking at putting a new tire on the X. Going with the Maxxis, but I cant decide if i should put the stock size or go with the 120/100. Are there any negative effects from going bigger? Is the 120/100 just wider? Is there a possiblity of the chain tearing the tire up?

Thanks!

Keep your chain a bit tighter than you think it should be and you'll be fine with the 120/100. Might rub on the mud flap but you can cut it down.

I run a 120/100 Desert IT and have no issues, as long as the chain is tight.

120's, depending on brand, may or may not leave parts of the left side nobbies on your chain. Be VERY careful when tightening your chain.....don't overtighten simply to keep it from hitting, as you will then be putting excessive stress on the counter shaft, this is a bad thing. If you have your chain tightened correctly, and it still hits the tire........you should either live with it, go back to the OEM, or put a spacer behind your countershaft sprocket.

I ran a 120/80/18 on my 03' R without any rubbing issues and loose worn out chain.

Somebody was talking about this recently, and mentioned the variance between manufacturers, and then listed the 120's that were slightly smaller and would fit better. Anybody remember the preferred models?

I've used the 120/100's with no issues. However, if you're concerned about it, just us the stock 110/100 size. I seriously doubt you would be able to tell any performance difference, they cost a bit less, and you eliminate the possibility of interference issues.

Bigger is not always better.

Thats not what "she" said....

Seriously- I agree- I like the 110 on the CRF.

The 120 is necessary on the 6fiddy (and it still looks like a tractor tire).

I used to run a 100 on my little KDX and it felt great.

If you add a ultra hd tube and a 120- the weight is noticable.

Thanks for all the info!!!!

      Hey guys I could really use some help. I bought a 2005 CRF 450x that has an aftermarket air filter, full FMF exhaust system (pipe and header), removed backfire screen, and removed air snorkel. Bike idles and starts just fine, but when I hold the throttle anywhere from barely at all to about 1/2 it bogs, wants to die, and backfires. Seems like lean running conditions to me because if i leave the choke on the problem mostly goes away. Additionally, if i move the air screw out almost all the way (to the point where it could vibrate off), it seems to clean up a little bit. I am trying to determine whether bigger jet(s) would fix it or if its something else. My dad thought it might be the float level, but I'm really not sure. Thanks in advance for your help!

      hi, I'm buying a crf450x and this is the first 450x I'm gonna own but i was a bit confused on one of the pictures. i checked on other crf450x pictures and could not find this on any of the others. There is a gap right below the air filter and above the swingarm and I was wondering if it was normal. 
       
      Thanks!!!

      I have a 05 CRF450X that was just rebuilt that is not starting via its electric start. I can start it with the kick starter as well as a rolling start down a hill though. Once started it seems to run just fine. I have it at a bike shop right now and they are stumped as well. So far I know the battery has been tested/replaced, the carb has been cleaned, jetting is good, and they have also tested the starter motor and things all look okay. Any ideas where to look next?
