As part of my weight saving plan I am ditching the stock seats and replacing them with a cheap set of lighter bucket seats. The factory seats weigh in at about 60lb each; the cheap eBay seats are about 30lb, plus a few pounds for the brackets I had to make to mount them.
I got the seats off the Facebook Marketplace for $200 for the pair, and spent about $50 on parts for the brackets.
I made a set of custom brackets so I can easily install and remove the seats using four bolts each in the factory threaded holes. A couple of pieces of 1/2″ square tubing and 1″ flat bar stock is all that was needed.
