03 crf450r chain length? please read!!

i bought a 112 link chain for my 450 and am gonna have a 13t/53t sprocket combo. the stock chain was 112 link but it was really stretched and i had a 51t rear sprocket and the tire was adjusted the whole way back. the chain is on its way so thats why im asking. i was planning on goin to my local track to ride saturday but that might not happen if this doesnt fit. any feedback will be appreciated. thanks a billion

get a new chain and cut to fit over the sprockets.. simple.

The stock chain is 114 links. To handle a 53T sprocket, you are going to need a 116L chain.

I always buy 120L and cut it to fit.. saves a little headache when doing gearing changes. Plus a chain breaker is a necessity for any bike riders tool box :smirk:

:smirk::smirk::foul:wat if i just left my 51t sprocket on there?

+1 on the 120. I'd try to return it and get a full refund. I got a did 120 x ring chain and I've got 20+ hours on it. Zero stretch. Love it

Do not know if it helps or not but I installed a DID 520 X-RING Chain 520x116 on my crf 450r 2011 with the stock sprockets rear 49t front 13t I think. And with the 116 chain it puts the axle in the middle of the swingarm settings.

you will need a chain stretcher..

JK :smirk:

you will need a chain stretcher..

Is that like a tile stretcher :smirk:

and your new chain will wear out to the old sprocket, always replace as a set

I have a chain stretcher its called a crf450

thanks for the reply and all but i could care less about my sprocket. i ordered a new one and its here now. its a 53t and if it doesnt fit with the chain and my old one does im using the old one. im sol:bonk:

located on the same isle in the store as a "tube of clearance" for when a head gets milled too much and the gasket isn't thick enough for adequate ptv clearance.. :smirk:

using the old chain on a new sprocket is a fast way to need another sprocket. It kind of depends on how worn, and i have stacks of older sprockets i use on bikes when we need a different drive ratio.. but when the teeth begin to slope even a little, it gets replaced. Im a big fan of the steel sprockets for dirt/harescrambles. $20 is awesome as vortex cut back on rider support (used to get lots from them for roadracing). THey last a good while on roadrace bikes, as they just are not running near the hours, nor in horrible conditions like a dirt bike.. so aluminum sprockets last a good while on them.

*new chain on old sprocket...not old chain on new sprocket

might as well call it an old chain after you use it on old sprockets

yup, chicken-egg, tomato-tomoto..

Would like to see a few PHOTOS of the old sprocket before we condem it to the recycle bin if he is on a major budget ? It has been a very long time since i had to really worry about $20 for a dirt bike, but can totally understand it can eat up every spare penny if not careful.

If I was you I would run the old set and send back the chain and get 120 link and cut to to size if you dont have a chain press you can grind the head off the rivet and drive it out with a punch

agree -

Back about 15yr ago I did the new chain and old sprockets :smirk:

Did not turn out to good and was a lesson learned the hard way.
