The CRF450 cam chain is used in built engines because of the increased tensile strength. It basically the same chain, at a cheaper price $35 vs. $75, and a much higher strength. It's not going to stretch as easily as the stock cam chain. You'll notice some side to side play, that's normal.

It is also wider, meaning it has more links, which make it probably 30% stonger than stock.

now can you put it in a stock bike? and is it a direct replacement?

actually I thought that at first too, but once you put the chain guides in the chain fits in those perfectly virtually eliminating side play!

Pretty sure it's still there on the top of the sprocket. Either way it's well worth the time and money.
