Yamaha’s YZ250 is one of the most important MX bikes in history – and it happens to be the longest-running production dirt bike in the world, as you can still buy a new one from Yamaha today. Here we’ve got a restored example of the 1991 model, in which Yamaha debuted all-new rear bodywork, “bold new graphics” (not in the sarcastic way that I usually say it), and some motor/suspension upgrades.
The ’91 gained a Deltabox swingarm with a new Monocross linkage, plus Kayaba “works style” cartridge forks up front. The engine got a longer stroke, upgraded cylinder liner coating, and an additional boost port in the cylinder. The seller of this example says “chassis, suspension, engine, body work, and more are all new or restored to new/show condition” as a “factory replica” and that it doesn’t need anything.
