The previous owner had already bought a Sargent seat and ridden on it for maybe 10K miles, so maybe that's why mine seems to fit a little tighter than yours. Pat is right about those fiddly front tabs, and compared to the stock seat (which I also got from her first owner) it does not fit as tightly or go on as easily. Of course I also have totally maxed out the amount of stuff I carry under the seat which adds to the difficulty of putting it back on.:yesnod:
Having said that, I have ridden both in the last month and MUCH prefer the Sargent. I also really like that document tube, which I am using for a 1st aid kit as well as documents.
