I have been wondering the same thing as well. I have about 10 hours on the stock 120/80/19 756 and it is just about time for a new tire. After looking at my rear and my buddys rear 756(110/90/19) on a crf450 I couldnt see much of a difference between the two tires as far as dimensions go.

It seems to be much harder to find 120/80 tires than regular 110/90's.

What about the 120/90/19's? They seem to be easier to get than the 120/80's but wouldnt they be slightly taller?

I am soo confused on what to buy next.

A 120/90-19 tire is made for 500cc 2 strokes. It is a big tire. The new thing is to get more rubber on the ground with a 120/80-19 sized tire. A 110 will spin easier than a 120.

So a 110/90 and a 120/80 should be about the same diameter/rollout as one another with the 120 being slightly wider right?

And the 120/90 would be the same width as the 120/80 but with a slightly larger diameter/rollout correct?

Has anybody put a 110/90 on their 08 and did you notice a difference? I am thinking that this 120/80 tire might have a little to do with the bikes incredible traction and hookup qualities under acceleration.

A 110 on my bike seems to be a little quicker handling than the 120 thats about all I notice

Matt - If your wheels came off of your '06 450 you are going to need a different brake side spacer for the front wheel due to the new axle/bracket.

I called white brothers today about mine, and a new spacer is in the mail - free of charge.

the 110s gonna be lighter, and you want as little spinning unsprung weight as you can get. the 120 may hook up a little better, but really on a 450 who needs to hook up more besides RC and JS7? I say go with the 110, the size wont affect the length of tire life. I've got a 110 on my 250f, just because with me on that bike, it needs to hook up better.

I disagree, I'm no RC ...but I have spun the 110 on my '06 plenty. I think especially on blue groove tracks a little extra "hook up" is good.

Actually the 120s are 30grams lighter (the main reason Yami chose them) according to MXA and they do cause more frontend push but better traction in loamy soil and sand. I think a better choice is to go with the 110s for better overall hook up for mixed soil types

As with any tire selection, it's going to depend on the soil type to a large degree, and to an even larger degree, what you like. The difference in width will affect the way the bike rolls into a turn a little bit, but you get some variation in that already just within the different profiles of 110's. The only solution is to try a few things and see what you like best.

I haven't used any 120/80's, and I don't see it happening soon, since there is such a limited selection in that size. I have used 120/90's, and they make a good desert tire, but their weight is noticeable in MX.
