Made my TW200 much more rideable
With the stock 50T sprocket, I was already in top gear at 25 MPH and was uncomfortable go over 45 MPH... With the 42T sprocket I can now comfortably cruise at 65-70 MPH all day. However you will need washers to use the stock bolts since this sprocket is thicker than the stock one.

Bolted right on, except I had to add 3 washers to each stud because the inner portion of the sprocket with bolt holes was at least an eighth-inch thinner than the 48- tooth sprocket I was replacing.
