I’ve read the main info page for the Hawk 250 on this forum and it mentions that you can get JTR279 sprockets in up to 42 teeth for a 520 chain. I can’t seem to find any of that specification. I’ve found a few that have six holes for the studs, but those won’t fit on the hawk, since it has four in a square pattern, and these sprockets wouldn’t fit the snap ring that holds the rear sprocket on either. I have found one that would fit on the hawk, but only has 30 teeth. I really would like to have 38 at the very least, preferably 42. I’ve found a couple weird, one-off 42 tooth sprockets that may fit, but they are either out of stock, being sold overseas, or on a very shady website. Does anyone have a link that I could use to buy a JTR279 38/40/42 tooth rear sprocket? The attached links are: the 30 tooth, which has the right position for the sprocket stud holes, and the 40 tooth, without the right sprocket stud holes.

The 42 tooth sprocket I have only ever seen sold overseas. It can be ordered, but not through US companies.
The 40, 39, and 38 sprockets are on Amazon. The first image with the 6 hole sprocket is just a generic picture and does not represent the sprocket. The second image with the diagram of the actual sprocket is the correct one to go off of, and is actually correct. For whatever reason the seller only put the right picture on the 30 tooth, but all 279 sprockets are the same in regards to hub and hole pattern. Basically, you already found what you were looking for, minus the 42 tooth at least.

Firstly, thank you so much, I realize now what you mean.
Secondly, I just goofed as hard as I possibly could. Not much of a gear head, but I now realize that, for more speed, I want a smaller rear sprocket and a bigger front sprocket. With what I was originally going to do, with 42 teeth, I would’ve lost speed in favor of torque. Biggest goof of the night. Thank you so much though! |
