- The front and bottom two mounting holes are dimensionally identical
- On the NC450, the CS sprocket is 9mm (.35") higher than the NC250.
So, in terms of a drop-in replacement, I'm not sure there's an extra 1.5" under the gas tank to accommodate the NC450 height, without some modification. And we would have to make sure the chain would clear the frame. There may be other frame fitment issues too. |
The rear mounting hole is also in the same location relative to the other mounting holes.
The top mounting holes are in completely different locations; on top of the 250 head and behind the 450 head.
I found the 450 sprocket to be about 2mm higher and about 13mm rear-ward of the 250's.
